Q: If I buy an ECU from you, what else will I need? I mean, are there any hidden extra's/costs that I have to buy after I've got the ECU, e.g. a relay board? A: As long as you have all the
usual hardware and sensors needed for a Fuel Injection System then NO,
you will not need anything else other than a laptop, some time and patience.
The ECU's I sell all come with a one meter long, fully labeled wiring
harness, an RS232 cable (for connection to your laptop) and a CD
with all the relevant software, drawings, etc. Q: I am running a Lotus 7 style kitcar with a 2.0 blacktop Zetec installed, basically in standard dress, except for exhaust manifold and a front facing inlet plenum. It is running a standard EEC V ECU. I am looking to run a MegaSquirt system, to extract some extra power and learn about mapping. But I want an easy solution to plug into my existing sensors or even Ford loom. I have looked through your site, but i would like some more information please. I know I will need a Tacho output, and would probably want to run the existing MAF unless MAP is a better option. It obviously needs to meet current emmissions so maybe a switchable map? A: You can use all of the Ford sensors, the
idle valve and the coil packs, etc, with the MegaSquirt's I sell. I
don't sell an adaptor to plug into your loom but the wiring diagram
is easy to follow and all you have to do is splice into your loom or
get an old Ford ECU and turn it into an adaptor between the Ford and
MegaSquirt loom. I have done this for several installs and it is a good
method of keeping the wiring in the car as close to original as possible.
You dont need the MAF sensor, we have a built in MAP sensor on the ECU
and this is the best option for you in my opinion. It's only a case
of piping it into the intake manifold (engine side of the throttle plate)
Q: Can I use my standard temperature sensors that I already have on the engine or do I have to buy special sensors? A: Well some engines have their
air temperature sensor built into the Air Flow Meter. As these meters
are generally removed to increase the breathing capacity on a lot of
engines then you would probably need to get an air temp sensor from
another vehicle or buy a MegaSquirt compatible sensor. So yes, you can
use the standard sensors but it depends on whether your going to remove
it. The ECU and the tuning software (MegaTune) would need to be configured
for the sensors. I can set up the ECU for your sensors for free, but
I would need 3 resistance measurements, see HERE
for more details on the measurements. I may already have done a set
of sensors for your engine, please download this file HERE
and check if your engine is in there. Just give me all the details when
you order and I will do it all for you. Phil Q: Can these ECU's be run without a Lambda Sensor? A: It is perfectly possible to
run without a lambda sensor but it's not recommended unless you're not
worried about the efficiency of the engine as the ECU will have no feedback
from the exhaust so it will not be able to correct the fueling. You
will have to have a lambda sensor to tune it in the first place unless
you're going to use a Rolling Road, as these are used to tell you what
Air:Fuel Ratio (AFR) the engine is running at. They are cheap enough
to buy (around £30 for a good Bosch sensor or £130ish for
an Innovates LC-1 Wideband) so I would
fit one if you don't already have one. The bung that's needed for them
to screw into the exhaust can be found in the scrap bin at any exhaust
replacement garage and they are usually given to you free. Phil Q: Do I need an MS2 ECU? Ive heard these are better and faster than the MS1. A: MS2 is basically a daughter board that sits in the socket that the original MS1 microprocessor lives in. It is indeed a faster processor and it has more ram. As it's a daughter board that replaces the MS1 microprocessor then an MS1-Extra ECU can usually be upgraded to MS2. See HERE for more details on MS1-Extra and MS2-Extra comparisons Phil Q: I am building a Fiesta
Mk3 with a 2.0L Zetec and just wanted to know how hard it would be to
use your system with throttle bodies, how hard it is to fit it and would
i need to have an old loom in the car to start with, thanks very much. Q: Hi There, I've been
thinking about one of these units for a while. I’m running a 1955
Buick V8 with an old Hilborn mechanical injection system that I’m
going to convert to EFI (They do parts to convert these including the
TPS etc), the system would only be capable of using the standard points
distributor. Do you know if the Megasquirt will work with this type
of set up? Ohh and nice work on the Cobra. Cheers Dave Q: Hi, I am currently modifying my
kit car to take a 2L Ford Zetec with bike throttle bodies, would the
MegaSquirt you have run this? Do you need to fit a separate relay board
or any other parts? Finally is it difficult to set the items up or is
it fairly straight forward when using the software. Thanks John. Q: Hello, my name is Kevin. I think
your the man to answer my questions & maybe help to get my project
underway. I have a BMW M535i, with Motronic 1.0 & Mass Airflow Sensor
etc. It will have to be built on a budget, but I have just bought a
secondhand, Eaton M62 Supercharger & I want to fit it to the car.
I am not going to do any mods to the engine internally, as I have been
told that I can may get away with about 8 psi boost? I am guessing that
I will need a complete programmable ECU, what do you think? Or do you
think I can add a couple of extra injectors & a boost retard sensor
with a piggy back computer of some kind, to sense boost (retard) &
add extra fuelling? I am very serious about doing this project as I
think it will be a very good Street Sleeper car. I will want to also
Drag race it at Santa-pod & get some 1/4 mile times. Thanks Kevin Q: What would i need to set up launch
control, shift lights and the switchable map tables. Also you say you
fit these how much just for an idea would it cost to fit this . Thanks
very much. Q: Hi, I am thinking of fitting an EDIS based Megasquirt to my Rover V8 EFI to run on petrol and LPG. What would be the best Megasquirt module for this and how much would it cost for you to supply it? I know this is a very large subject but I am just trying to get an idea of what I need and the cost. Thanks Ben. A: Hi there, the EDIS system is a very reliable setup that is not prone to noise, etc, so is a good way to get wasted spark. As for LPG, the best option would be to have it wired for switched tables (so you run one fuel map and spark map when in petrol mode and a completely different one in LPG mode) this will allow you to tune the 2 fuels virtually independently. For adding a switcheable input I would charge £8 more, so its not very expensive. Good luck with your project, Phil Q: Hi there, I have read your FAQ's and have seen the one about the 2.0L Zetec and bike TB's (throttle bodies). I am very new to all this, so I need help, I want to purchase this MS system but I don't know what else I need. I'm running a kit car with a Ford CVH engine, I'm changing to 2 liter Zetec with Yamaha R1 ITB's, what will I need on top of this package as far as wiring goes? A: Hi there, as far as wiring goes you need the relevant plugs for all your sensors. You should already have all the sensors needed on the engine, Air Temperature Sensor, etc. Virtually all original equipment sensors will work fine with the MS ECU. Your Zetec would have a crank sensor on it and a 36-1 trigger wheel which can be used directly with a V3.0 MS. You should also have a coil pack sat on top of the engine, this can be directly driven from this MS ECU V3.0 too, so you'll have fuel and ignition control in wasted spark mode on your setup with this MS. Phil Q: Hi, I am building a BMW 318is M42 with throttle bodies, high cams, etc. With this system, can I get rid of the MAF so I can put on a DTM carbon airbox, so the ecu controls the air mixture? thanks A: Hi there, yes the MAF (Mass Airflow Meter) can be thrown away if the hardware allows it, as some setups have the MAF built into the inlet manifold. The MegaSquirt ECU's have a built in Manifold Air Pressure sensor (known as Speed Density mode) which you can use or you can use a Throttle position pot (that's what's called Alpha_n mode). It can even be adapted to use a MAF if it has a 0-5V output signal (e.g. a Ford item) so yes, the restriction of a MAF can be removed if you so desire, Phil Q:Hello, how much is shipping to Greece? I know everybody asks you if this ECU will work on their car, so just to make sure, I'll do the same. I have a Renault 19 1.8lt 16V and I want to install ITB's. What else will I need besides what you're selling to make this ECU work on my car? Could you have it programmed if I gave you all the info you need? And finally, if I have a professional ECU tuner have a look at it, could he get the best out of it? thank you (for your patience). A: Hi there, the postage to Greece is £15, that is fully insured postage that has to be signed for. You'll need all the relevant sensors that a normal EFI setup needs (Air and Coolant Temperature Sensors, a Lambda sensor, a throttle position sensor and compatable trigger input from a coil / crank sensor or a distributor) If you want to keep the original sensors that came with your setup you can. There are instructions on the CD that I supply on how to use different sensors with the ECU and the software or I can do it for you if you give me the information, see HERE. I can't preprogram an ECU that's ready to be used without tuning. I can pre-load the ECU with settings for your engine with a base map, etc, but it will need tuning for your setup. If you can find someone on the MSExtra forum that has an engine the same as yours you may find that a lot of help, but the best thing to do is to read the manuals I've compiled and learn how to do it from scratch, its all part of the fun of it. Any good professional tuner should be able to tune your engine with an MS ECU, but you'll need to take the software (supplied on the CD) with you for the tuner to use. Phil Q: Hi there, do you build these in house or do you get them made elsewhere? We have an on (and on and on) going project that requires radically re jigging the Zetec engine and then running a supercharger on top. I looked at the old V2.2 MS units about 18 months ago and they looked very good value and the spec/drivers pretty impressive to say the least. If your building them can you supply the ECU only as we have full loom build facilities of our own. Thanks. A: Hi there, I build the ECU's myself in my workshop, I'm an Electronics Engineer with over 25 years of experience. I will supply them without a wiring harness if that's how you want it. The upgrades I do are the uprated Idle Valve output (FET) so it can directly drive 3 Amps to the valve, this allows us to control Ford valves and the like in PWM mode. The original transistor simply isn't up to the job of driving an idle valve directly. I can also offer numerous spark output and input options, etc. Basically I'm selling the ECU's ready for use so the end user doesn't have to modify them, Phil Q: Hello! This is a great system! Can I use it on a motorbike? I have a Honda GL1000ccm, flat four engine, 61kW@7500rpm, watercooled, waste spark ignition with two coils (so each of the two coils supplies two cylinders). But the ignition system is fine, I only need to control fuel. I can build an intake manifold as I am a good welder. Problem could be that I have no sensors on the engine, so You would have to tell me what I need to make it working (sensors, throttle plate, fuel pump, injectors, wiring diagram). I have 12V negative ground electricity. Thank You Ray A: Ok, thats a great project. Fuel control is easy to do, well its not too bad lets put it that way. Take a look at the drawings section, there are drawings in there for you to download that would help you get a feel for what is needed. But basically you need a lambda sensor, a throttle position pot (TPS not needed if you have a plenum but you need one for ITB's), a high pressure fuel pump capable of around 40psi, 4 injectors, an air temperature sensor, a coolant sensor, fuel pressure regulator and fuel rails. I would think the easiest way would be to get them from a scrap bike with injection already fitted. Phil Q: Is this ECU a plug'n play system for Peugeot engines (both MI-16 and 106 GTI)? What other modifications are needed to put it in a Peugeot engine? A: Hi there, sorry these items are not plug-n-play ECU's, they all need to be tuned for your setup, etc. I supply the software to do this with and it's not too hard to do. I have fitted MS's to a few Pug 106's and to several RV8's and Zetecs, (as well as other cars) and none of the same engined cars have the same map in it as every engine is different, the base map should help get you running but they need to be tuned for your setup. They also need to be wired into your engine, this isn't too difficult in fact most people are surprised how easy this is to do. The 106 should have a suitable 60-2 wheel as standard, we can use that to feed the MS ECU. Phil Q. How do I tell if my distributor's sensor is a Hall Effect sensor or a Variable Reluctor (VR) sensor? A. Generally if you're sensor has
3 wires then it is a hall sensor, if it has 2 wires inside a screened
cable (cable with a braided casing around the outside of it under
the insulation) it is likely to be a VR sensor. To check this you
can turn the ignition on, ensure the sensor and original ECU, etc, is
still connected as it should be, and slowly turn the engine over (remove
the distributor cap so it doesn't spark) If the voltage switches from
5 or 12V to ground (0V) then you have a hall sensor. It is important
to know if the voltage is 5 or 12V when it see's a tooth or if its see's
a gap between the teeth. |
