PCM Diagnostics & Tuning - 98 auto plus nitrous
07-17-2006, 03:08 PM
I have a 98 camaro with a ssf 3500 with a tnt 100 shot. When i am running all motor it shifts into second at 5500 but when i am using the 100 shot it shifts at 6100. Also when i make all motor pass no matter what technique i use to launch i cant get over a 1.90 sixty. I think my nitrous times of 7.33 with a 1.71 isn't bad, i just want to get my all motor better. What kind of tuning tricks can i use on my auto. Thanks.

I would say slipping clutches is the cause of the later slip, if you are commanding a shift at 5500 and they are going to 6100, that or i have seen sometimes where the plastic forward accumulator piston is cracked in your trans causing that same issue.
I would check that first. Then add more pressure or get a shift kit if you can. As for take offs, i would have to see a running log on what is going on to give you an insite.

no i have no tune, but the stock one. it used to shift at 6000 but once i got the stall and shift kit it changed on the 1 to 2 shift.

hmm, you need a tune with the shift kit for sure.
It is very important to get rid of a couple things in the tune.
Tm and Shift adapts being the most important.
