Fuel Only Setups
GM HEI Based Setups
The Fuel Only ECU's allows fueling to be controlled on virtually all types of engines, this can be modified at a later date for ignition use if needed. The ECU will give you control over your fueling with a 12x12 table (16x16 on MS2), allowing you to tune the engine properly.
Note: This ECU doesn't control ignition as it is Fuel Only

This ECU is designed to read the signal from the GM HEI module and trigger the HEI to fire the coil through the distributor.
This ECU will give you control over your ignition map (12x12 table) and your fueling with a 12x12 table (16x16 on MS2), allowing you to tune the engine properly.


Distributor Based
Setups
Toyota VAST
(2S-E, 22R-E, 22R-TE, 4Y-E & 4A-GE)
The Distributor based ECU's consists of a single
direct coil output for use in a distributor based setup
suitable for even fire 1, 2, 4, 5, 6, 8, 10 and 12
cylinder applications. It is ideal for engines with a single coil (Distributor). These ECU's will give you control over your ignition map (12x12 table) and your fueling with a 12x12 table (16x16 on MS2), allowing you to tune the engine properly.
How to tell if you have a Hall sensor or a VR sensor in your distributor

This ECU is designed to read the input from the
Toyota VAST trigger wheel and then fire the
original ignitor.
(It can also fire the coil directly if you wish)
This ECU will give you control over your ignition map (12x12 table) and your fueling with a 12x12 table (16x16 on MS2), allowing you to tune the engine properly.
This includes a Tacho Output as standard

See HERE for more on the VAST setup.


EDIS 4, 6 and 8 Setups
Electronic Distributorless Ignition System (EDIS)
Ford TFI Based Setups
Ford Thick Film Intergration
(TFI)
This ECU is designed to read the very popular PIP output from the Ford EDIS 12 pinned module and drive the SAW input telling the EDIS module what angle to fire the coils at. It is ideal for a wasted spark setup when wanting to use the Ford Edis module and coil packs. These ECU's will give you control over your ignition map (12x12 table) and your fueling with a 12x12 table (16x16 on MS2), allowing you to tune the engine properly.
Also see my used EDIS6 and EDIS8 kits
(Used, Crank sensor(VR), EDIS module, coil packs, HT leads, 36-1 ring and connectors)

This includes a Tacho Output as standard
This ECU is designed to read the very popular PIP output from the Ford TFI module and fire then send a signal to fire the coil through the distributor. This ECU will give you control over your ignition map (12x12 table) and your fueling with a 12x12 table (16x16 on MS2), allowing you to tune the engine properly.






Wasted Spark
4, 6, 8, 10 and 12 cy Setups
4 Cylinder Coil-On-Plug
(COP) Setup
This setup has either 2 spark outputs (4cy), 3 spark outputs (6cy), 4 for a V8, 5 for a V10 and 6 for a V12 making it perfect for running a wasted spark configuration with coilpacks. This is also suitable for use with a single coil (distributor based setup) when wanting to upgrade your engine to wasted spark at a later date, please let me know if this is the case. It is an ideal system for Distributorless setups that have a crank sensor and wheel.
These ECU's will give you control over your ignition map (12x12 table) and your fueling with a 12x12 table (16x16 on MS2), allowing you to tune the engine properly.
10 and 12cy wasted I mount the spark drivers seperate to the ECU, see here.

This includes a Tacho Output as standard
These setups have 4 spark outputs (1 for each Coil)
Wasted Spark COP: This ECU is designed to run on a 4 cylinder engine with COP's.. This means that 2 x COP's are fired together and only needs a suitable crank signal (e.g. 36-1, 60-2).
Sequential COP: If you have a suitable cam signal (1 pulse per revolution) and crank signal (e.g. 36-1, 60-2) then we can now use both these to give a Sequential COP setup, that fires one plug at a time.

These ECU's will give you control over your ignition map (12x12 table) and your fueling with a 12x12 table (16x16 on MS2), allowing you to tune the engine properly.
This includes a Tacho Output as standard

4 Cylinder
Sequential Fuel Setup
6 and 8 Cylinder
Semi-Sequential Fuel Setup

This ECU has 4 fuel injector outputs so it can run each fuel injector in a fully sequential operation. See HERE for more on sequential fuel. This allows you to tune the exactly angle during the ENGINE cycle that the fuel is squirted into the engine for each cylinder. The ignition can either be coil packs (wasted spark) or COP sequential.
Please note: A suitable cam signal is needed to run full sequential (1 pulse per cam revolution) and a suitable crank signal (60-2, 36-1, etc) the code for this is still experimental.
These ECU's will give you control over your ignition map (12x12 table) and your fueling with a 12x12 table (16x16 on MS2), allowing you to tune the engine properly.
This includes a Tacho Output as standard

This setup has 3 (for a V6) or 4 (for a V8) fuel injector outputs that can run the fuel injectors in pairs in a Semi-Sequential fuel pattern. This allows you to tune the exact angle the fuel is squirted in during the CRANK cycle, so half will be squirted in during the exhaust stroke (inlet valve shut) and the other half just before the inlet opens, see HERE for more on sequential fueling.
Please note this needs a suitable crank signal, e.g. 36-1, 60-2, etc.
These ECU's will give you control over your ignition map (12x12 table) and your fueling with a 12x12 table (16x16 on MS2), allowing you to tune the engine properly.
This includes a Tacho Output as standard

These ECU's all come with the standard options
Take a look at the Extras section for more options

Add on's :
Some of the following can be added depending on your setup, see the tables below:

# NOS - Nitrous control (An output to drive a relay coil that's triggered by a minimum RPM, TPS, etc; It also uses an input that switches to a new timing map or fixed ignition retard. Can be used as an Anti-Lag for turbo applications too. Buffered, flywheel protection circuit +£12 Please Note: This is counted as 2 options, 1 for the input, 1 for the output, so only 2 more can be added) See HERE for more details

#NOS - Nitrous control for MS2-Extra Only (up to 2 outputs to drive a dual stage or single stage NOS setup that's triggered by a minimum RPM, TPS, etc; It also uses an input that switches to a new timing map or fixed ignition retard. 2 x Buffered, flywheel protection circuit +£15 for 2 outputs or +£12 for 1 output Please Note: This is counted as 2 or 3 options, 1 for the input, 1 or 2 for the outputs) See HERE for more details.

# Dual wheel decoder/2nd trigger input (For a second hall sensor input opto protected circuit with hall conditioning +£15 For a second VR sensor input including separate VR conditioning circuit +£35)

Up to 4 additional items like, launch, prog outputs, knock, etc can be added. For more info on these functions please contact me.

- This code is experimental although some people have had some considerable success with the system.
- These options work for most installs, but as there are so many variants of rev counter it is impossible to say it will work on all setups. You may need to add a few components externally, but full details are supplied in the drawings.


How to Order

I accept PayPal, cheque or postal order as payment.
But please contact me with your setup details before purchasing so I can advise you the best ECU for your project.
I can then setup the ECU with a base setup to give you a slight head start.
I'd rather you bought what you really need and were 100% happy before going forward with your purchase, thats why I don't have a basket/shop function on the site!

Please Note: Generally there is a 2 week lead time between payment and dispatch, this can vary a little depending on current work loads, stock levels, mods you require, etc.
