GST -supposed to be a Turbo model/

07-11-2010, 05:56 PM
I had my local mechanic change the ECU due to driveability issues, now it only runs about 3 min.s then dies? The car is a USA made GS-T, 2.0 liter. Is it supposed to be a turbo model? (car doesn't have a turbo). Could the prob. be due to incorrect ECU? I paid this guy $1000.00 to fix it and it has sat a year now. Any help in how to identify proper ECU for this car would be much appreciated. I'm thinking of running an OBDII scanner to see the codes myself, and do the work myself. thanks, tom pauly

Whats the year, make, and model? The vin number could tell you exactly what it is too. Since you mentioned obd2, I'm going to assume that it's a 2g (95-99). And if that's the case and there is no turbo, then it's got to be a 420A. I may be wrong but you could always post a pic of your engine bay and we can tell you exactly what it is. If your standing in front of the car facing the engine, what side is the tranny on? If it's on the right, then it's a 420A. If its on the left, then it's a 4G63. Only the GST and GSX came with the 4G63 and they were turbo as well as the TSi Talons. The 420A came on the GS and RS Eclipse's as well as the ESi Talons.

Hope this helps you in figuring out if you have the right or wrong ecu.
