how would a car with a bad map sensor run?

it is shifting into second gear at 27mph. on a scale of 1-10 it is at about 5-6

Throttle Cracker - Is there a custom PID and MAP that has been made or that can be made to log what is the desired airflow for the cracker table? (just like the RAFPN AND RAFIG PIDS)?



Missfire...

Ok, I managed to get the shifts to where they are not SUPER crisp to the point they were making my rear view mirror move.

I'll post tune later.

What I did is I upped the torque reduction on...

Another thing I want to add. I suspect part or the greater part of the problem is power (electrical).


Every time when the car is barely turned or several minutes later the car idles and I can...

Weatherman,

I appreciate the help, I really really really do. At this point I honestly dont think I can do a tune from scratch (noob). I would prefer to reseal the fast 90 and double check...

My idle issue are NOT resolved. With the current tune it is better, but not fixed.

I have been suspecting for a while that the car wasn't properly tuned. My tuner did use a wideband, I watched...

I have no idea how it worked. This time around it just worked. I suspect my obd2 port on the car is bad, every time I a bump it looses communication. I will be replacing this.

The car does idle a...

maf calibrations from a z06 or a truck maf is way off from what i have in my actual tune. My current maf is from an 03 silverado, it originally came with a screen, but i took it off. Should i bout...

d1101 2 3 set all the values to -30?

d1107 all values to zero?

will try this in the morning

I have been running on a stock transmission tune. That is what is giving the hard shifts.

I saw the tune, spark is definately way different than mine. Also the misfire tables are way different. What do you guys thing about this tune.

Check the tune out. Should I lower the torque reduction #s that i added on there or should i try those for the 2-3 shift? Those #s along wtih a higher mph.

Let me know

This is what I did. I changed the shift times to higher speeds for 2-3 3-4. It seemed to work atleast anything below 12%tps. Anything above 12% generates to much engine torqe which gives me...

The missfire thing on ls1's is fairly common over on ls1tech. It's also a performance built tranny so it wont shift like stock. It can be something simple like my motor mounts are shot, which i think...

i spoke to peformabuilt. They say the little clunk i get from 2-1 is normal. Since they replace a spring with a steel one or something like that. So im good on that issue.

He said to try to raise...

Joecar - yes im running maf


ls1dragster -

These are my mods, the misfire is most likely the cam. Car runs fine and good, no power loss or anything, its just the tranny thing. Do you think...

This log was from the morning driving to work. Let me know. I checked the fluid level and it was fine when hot and in park. I added a little just in case, it seemed to have ran a little better, but...

one more thing below is a list of things that i think can help let me know.


D0705 (if i lower the amounts below 0 on this table, in theory it should reduce torque right? maybe it has too much...

[QUOTE=LS1_Dragster;128175]The issue is this, your stock settings didnt work, my settings on my 3 vehicles works fine but not with yours and there have been others that have used the trans segment...

what would happen if i put d2801 to yes?
