heres one for you all,
can the simtek ecu on a 95 engine check the tempreture of the intake air flow, and work I/C water sprayers to regulate said tempretures?
thanks,
phil.

Cant help you on that year but my 97 sti with simtek runs auto intercooler spray with a sensor in the intercooler pipework, im pretty sure yours will be fine, best sending a message off to one of the mappers on here.

thats good to know it works on the later ones, looks promising, i did have a sensor in the pipe work, it was connected to the maff plug with 2 wires, any mapper know if it will work to the earlier ecu's, and will it need a mapper to sort it once fitted?

MartynJ

Yes, it has a water spray output on the early ecu too.

thewhitewarrior

very good, thanks :-D what wire from the ecu is used for the sprayer, and does it need a mapper to set it?

MartynJ

Yes a mapper needs to set it, I don't have the pinout info availabe at home, so I'll try and get it across to you tomorrow.

thanks very much, ill have a geuss at the pin out being one from the maffs old plug as its only used for the air temp sensor?

Can the 'auto' function be mapped on the Prodrive ECU?
if so, whats the function linked to... Boost, Temp etc?

Only wire connected to ecu in maf plug on early car is the maf input and now its air temp input.

Should have pinout here. Will check

thewhitewarrior

ha ha shows im not that good at guessing, when i get sprays fitted and wired up using the correct pinout, will the ecu already work to a set tempreture or does it need programing?

In my base maps I have them setup but your ecu wasnt one of mine so will have to check as if I recall correct I had to load a particular base map to suit this ecu as it had had an altered firmware on it.

thewhitewarrior

very good, did you find which pinout i need to hook the positive to, ill source the parts and get them on and you can work your magic simon :-D
