Thread: I'm like Ricky Bobby, but my car says no, you don't wanna go fast.

So you can see my KR is gone (used to be bad) and cell 316-320 is downshift kr that I can't get rid of (yet). The misfiring is gone too, but the problem is lines 352-357. I can wot but I have my boost disappearing and now power. It has done this a couple times now. Once I stopped gaining speed completely. It doesn't feel like a rev limiter, its just all of a sudden no power.

First time I'm posted on it. Could it be tune related? Maybe try importing my trans, timing and fuel tables into a new bin and doing a full write?

I wanted to go fast from lightfoot3b -- Scan Depot dot net

two things first, your shiftpoints are so low! and your 02's are so high!

Looks like some tq management to me, i was going to say wicked belt slip but after closer examination i threw that out.

your shiftpoints are so low!

I know, I have been having shifting issues (I count this as a shift issue since once I'm in 3rd gear it did this). Once its right I will take it up a little higher. (I accidentally took her to 6300 in first once, that was an experience, didn't know rpm table did the shifting back then, thought that table was a rev limiter!)

What would you suggest I shift out of first and second at? Have it so I see about 5900 as the max rpm in each gear?

and your 02's are so high!

If I try to get close to 920's I have kr city even with low timing. It is like my O2 sensor is -40 on its readings. If I sit 960-980 the car runs like a dream. That took a lot of maf above 7.5k to get right, but it works!


Ok the problem was solved by me mass importing the performance shift table, shift time table and torque management table into my current tune. Then I did a FULL WRITE and walla, I did 93mph and proceeded to stand on the brakes.

My car only works after I post questions. See: me posting a lot more questions

So we can call this one fixed?

Sorta, but not until it is tested a couple more times with raised shift points (and some people tell me what they think the best shift pts would be).

Okay, lemme know then cause I'll make a cliff notes version and mark it fixed. The goal being to eventually have some area for troubleshooting information. So everyone coming across issues like this will have some reference point to begin.

Grr. It is fixed, but now the car feels funny shifting into second. It studders and pulls all timing.

now i know that youre having other problems, but could your s/c belt be slipping.

I'm going to go with a "no". I have wayyyy more problems then this now. Now I have 2-7* of kr (on the same tune as before) over 50% throttle. If I'm rolling like 25mph and go 75% throttle I see 15* of kr. Yeah, go figure. -7* out and I have mad kr on 970 O2's.
