92 4g63 turbo ecu in 89 4g61

[Hiitman]

I sold my old ecu out of my 92 tsi to a guy with an 89 mirage (4g61 motor with the 11b). He said he's having idle problems so I was wondering what pins he has to switch and if those ecus are even interchangeable.

Send it to dsmchips

That link show it working from a 1990 into a 1991 and up dsm ecu not a completely diferent motor,Im not sure if taht will help?

read it closely "I now sell a small tach adapter, which will convert the 1990-style tach pulses to work with a 1991+ ECU", you still need to swap pins 6 and 14 when using a 1991+ ECU in your 1990 DSM

I didnt know that the 89 mirage was called a 1990 dsm thats all Im saying .Diffrerent motor and turbo and still wrong year.
with an 89 mirage (4g61 motor with the 11b).

You can use a dsm ecu in a mirage if you get the right year,for example an 89 mirage can use a dsm ecu from 89-90 or use the 91-94 if you do that pin swap & tach adapter

Even though they have a completly diffrerent motor?i know the EVO guys are using dsm ecu's but thats still a 4g63 plant same liter size and all.But I guess It can be done then.

The 4g61 is a replica of of the 4g63, almost everything is the same but the only thing different with the 4g61 is that it's 1.6 instead of a 2.0, 4g61 and 4g63 parts are compatible to use

Yep the computer doesn't care what the displacement of the motor is. As long as the sensor read the same.

Nice info good to hear now Ive learned something as well!

We call them CSMs.They ecu will run a little lean .As the stock 4G61 injectors are 390cc's.Also the MAF has the lower half covered.The 61 has no BS.Where do you think the OEMs BS removal kit come from?
