I have a 4plug ECU with an extra board fitted but I don't know what it is!It has two big chips on it with a sticker hand written STINLO8R 18R M10 and STINLO8R 18R M20 it also has 3 wires coming out of the extra board red white and blue.Can anyone tell me what it is please?Many thanks Steve.

 

JGM any idea?

 

Picture may help.

e.g this is one of various boards that have been fitted to early cars

ScoobyECU

 

This is it

 

Power engineering did one similar to this you'll find its a piggy back board providing a modded Map. Is your car modified, usually these board are used for cars with basic mods, such as decat and exhaust, uprated fuel pump, and air filter and possibly a few other minor tweaks. Usually run approx the 300bhp margin.

 

Yes my car has a full de cat,air filter,fuel pump.Will it be ok to run my car with this ECU?Do you know what the 3 wires are for?

 

Can this ECU be remapped?

 

I do not know what the wires are for mate, you may want to ask one of the mappers what its for.

I think you'll find the mappers will not touch these as they use machine code which isn't mapper friendly (takes to long to programme) hence why majority of these chips and boards are a bulk manufacture therefore pre-programmed.

You could ask the question though, i only got to ask one mapper and my car got written off, so never carried out any further enquiries.

 

Anyone know what the three wires coming from this ECU do??? Thanks Stevie.

 

JGM anyone

 

Can anyone help to ID this????

 

Bump

 

Could be a 2 stage switchable board, The 2 chips would have 2 different maps and the wires would allow you to switch between the 2

 

You have 3 choices:

a] Fit it, and take the car to a knowledgeable rolling road and have it checked.

b] Fit it, do nothing else, hence risking the engine. (unknown map)

c] Remove the board, rejoin the J1 and run the 'safe' OE map.

RE the wires.

Didn't Superchips do something similar to that? I think in their application the wires went to a fuel cut defender...
