S300j problems Car running in permanent limp mode
Posted: Thu Aug 16, 2007 7:22 pm
I just got back with my GSR ecu which i had the S300j installed in.
When the guys installed it they had a problem with the laptop reading the ECU on 2 cars but when they reinstalled the software then the laptop reconised it. However/while it was giving this problem they thought it was the socketing, so the guy took it and did what he called a "circuit test" and said that the ECU is fine.
During the testing process I saw a solid red light, but when i asked what it was they told me that i would see a red light before a program is uploaded.
Now that i have gotten home and plugged the ECU into my car i still see the red light so i uploaded a program but the check light stays on, then i start the car, it idles at 1500 rpm and limits at 3500rpm. I tried different programs, and nothing. The CEL stays on constantly. I cant datalog or nothing. nothing works. I dont live close to where i had it installed actually i live thousands of miles away ( in different countries) and really cant afford to ship it out and be without the car for extened periods since i just finished my vocation and i am goin back to work nextweek, and the car is my daily driver.
Is there anything that i can do here that could solve my problem?
In the install manual it says remove J4 resistor and transfer to J1 ? does the resistor need to be there or can there be a thin wire acting as the jumper?
Is there anything else i should look for/look at ?
Can i test for continuity between any contact points to check to see if the board(s) are working correctly?
The ECU was working perfectly before, so i know it works.
Need Help ASAP
