Hey guys,
I've been having some issues on my car:
1)Idle Issues
2)Turbo starts charging at 5,000 RPM
I have a 97 Eclipse GS-T with a recent engine swap (previous owner had it N/A) 4G61T and a TD05 16G turbo but the ECU is from a 4G63T, i am wondering if the ECU is causing these problems and what are the pros and cons of running this.
Thanks in advance.
First of all, I'm sorry that someone did that engine swap, because that's a major downgrade in performance.
Secondly, the symptoms you're describing probably aren't caused by the ECU. It's normal for a 16G turbo to be pretty laggy on the 1.6L Engine. I would do a compression test to make sure the engine is in good shape. Idle issues are extremely common on these cars. You should find out for sure which injectors you have, because the car will run funny if it still has the smaller 390cc injectors that come on the 1.6L engine. Swapping to 450cc's from a 2.0L should help somewhat, but it's likely that you'll always have idle problems with the car. Trying to troubleshoot an idle problem is usually a huge pain in the ass, it could be caused by hundreds of different things.
