Advancing the timing on the 3.8 January 11, 2008, 10:12:37 PM Just wondering but has anyone here advanced the timing on their 3.8 over the factory 10* BTDC? I'm just wondering if the 3.8 in my 95 would like that or not. Since the 3.8 in my 95 is similar to the 88 3.8 I was wondering if any of you 88 V6 guys had done it. I know 5.0s (like the one in my 88) respond well to a timing advance up to 14* or more. BTW I know how to advance timing and listen for ping and such. All the guys over at tccoa tell me how to do is advance the timing....... http://forums.tccoa.com/showthread.php?t=108382 Quote Selected

Advancing the timing on the 3.8 Reply #3 – January 12, 2008, 10:55:41 AM You might consider finding an aftermaket chip/computer for it.I ran one in my '96 for a few months back in '05. It altered a few things, including shift points, timing, etc.The car would burn the tires off if you stomped it from a stand-still, and it got sideways during the 1-2 shift at WOT. Of course, I removed the lower spring in the 1-2 shift acspoogeulator which had already firmed up the shift, so it was kind of a double-whammy.It felt so much faster over stock, but I eventually removed it because it was too much. Driving it in the rain was really annoying.However, it may be exactly what you're looking for with the 3.8.In the mean time, I strongly suggest you install a transmission cooler and upgrade the shift acspoogeulator pistons in your 4R70W.Sorry to hijack your thread; I thought you may find this information useful.

It might help with the shifting. I swear the AOD in my 88 respond to changes in throttle position better than the 4R70W in the 95. I have a feeling that is caused more by the engine in the 88 than the AOD being a better trans;) . In reality I would love to put a 4R70W behind the 5.0 in the 88 if it wasn't so expensive to do so...... Quote Selected
