Hi Guys/Gals
picked up my wifes 2002 wrx sti type uk today after her type ra was stolen!!!! I didn't notice untill i got it home but the MAF is not connected and 2 wires have been cut from the connector. These 2 wires have then been wired into some sort of sensor on the underside of the intercooler any ideas WHY????? and what i should do about it?????? Thanks in advance

cheers
Tim

 

If its got and aftermarket ecu that doesnt use a maf, eg simtek. The wires could be connected to an air temp sensor, and its easier to use the existing loom back to the ecu.

Is this a replacement car newly purchased?

 

Hey Andy

Yes got the car today other than after market lights its totaly standard even got a mild steel exhaust!!!! I havn't checked the ecu but everything else looks untouched

 

bttt

 

I would recon the standard ecu is using charge temp sensor instead of measuring temp at maf which maybe quite a good idea

 

I reckon on it having a Simtec.

Does the sensor look something like this:



If so then IMO its got a simtec

 

thanks for replys
should i get it looked at? i havn't had the time to get a good look yet but will remove intercooler later in week to get a better look. the car feels a bit flat but i'm used to a daily drive with much more power so i can't tell!

 

i can.t see the sensor its on the underside of the intercooler but from what i've seen it looks like the one you show but it's black. Looks like a temp sensor to me

 

this car is totaly standard from what i can tell

 

have you got any contact details for the previous owner then? maybe they could help you

 

not yet only got car today so won't see log book for a week or so. its only done 29,000 mile but has limited history but it was cheap

 

I see where you coming from. But why would you have a simtec on an otherwise standard car. Unless ofcourse its been put back to standard. I have a similar sensor to that picture in my intercooler but its only there to measure charge temp on a gauge

 

you would have thought that they would have removed the simtec when putting back to standard

 

bttt

 

Not necessarily as they may have sold the old ecu on. IMO you`re best bet is to try and get hold of theprevious owner. Thats your best bet of finding out what exactly is going on. Alternatively, take it to a tuner that will have some idea of what it is they`re looking at

 

If its a simtek, you might need to remove the ecu casing unless someone has written on the outside of the case.

 

If it is a simtek, I will gladly swop my standard ECU for it.
