So I do alot of tuning on V8's and related transmissions, however I had my father ask me to tune his 2010 2.4L Malibu because he said it feels so held back, which is the case as because of torque...

Just realized I posted this in V6 can a mod move to GM L4, I5, I6 Transmission Tuning

So I do alot of tuning on V8's and related transmissions, however I had my father ask me to tune his 2010 2.4L...

Well my first approach would be to fail the O2's so to get rid of that code, then clear DTC's in scanner and do a complete log and post with tune, cause I'm kinda going off of experience.

"IAT...

Yep just as I was thinking, I never got a chance to look at the tune at work.

Not sure but here is a shot in the dark, I had the same type of thing happen when I changed gears and did not rematch my WOT shift speeds and RPMs when I closed the gap on that it went away.

Now...

Right click and save to hard drive somewhere, then rename the file extenstion to .cfg (it is .html when downloaded)

Good to hear it worked out.

Russ K beat me to it, i was missing my system not using beta, but he hit it right on the money. I would say let me know if it dont work, but I learned from his posts, soooo...lol

K, ill have you closer Im pretty sure or fixed, when i get home later tonight. do you have a aftermarket Stall?

Kinda crazy my 04 Silverado had the same issue today. I had put a new battery and starter in, and after startup, ECT read zero, did a Scan and found there was a code for something coolant related...

Well starter and battery are in a doing great, but the change did nothing, its crazy 20+ or -mph roll nail it, and 1.5-2secs later it seems to kick back and leap, like i need to adjust the throttle...

Google is right... IMO a shift kit, is a mechanical increase in pressure and efficiency (least in the case you explain) so to fix your issue correctly id remove 1 washer. At least that way you have a...

Ill get back to ya soon, replacing a starter and battery tomorrow well battery... who would have thought that a battery would loose a cell and the starter go bad at the same time, but i confirmed it...

I can tell you that when i did that with my 04 Silverado 4l60E it was not nice the shifting was not working any better, it actually seemed to shift too soon, like sonner then stock like a fail safe...

Some new updates, I have also been tunning my pops truck with about the same mods etc except, his tires and wheels are smaller and its not a EC, otherwise the same, and his is instant like a cable...

Thats what i have been working with now but still seems to not make a difference... Maybe i still havent hit the right spot.

...well its super crazy i did a log of transmission pids and all, and it even shows that its downshifting to 1st but there is a lag that acts like a carb boging, or a TB not opening then it jumps, so...

Ok not sure the actual tires and gears you have but im assuming that the tune is right, that aside i see something that dont look good.

Auto Shift Speed>Full Throttle Shift Speed, 1-2 Shift is...

Yeah i zeroed them out to try and see if that was causing it, so either way it still lags.

Yeah those settings was the 1st thing i did when i got HPTuners. And adjusted Torque Management

Yeah, I wish it did not.

I have taken the ECT limits away as well under torque management

Here ya go...
04 Silverado
CAI (Homemade)
Exhaust
Still need to install Vette Servo

SO I have a screenshot of a log and the area in the yellow box is the problem im talking about, basically you see the TPS go 100% but almost 2secs happen before the RPM and gear kick back happen. I...

Im going to create a new Config so i can see what the gear and TCC is doing. But basically it feels like to me from back in the day cars ive built like the tranny is not kicking down in gear quick...

Just did a long a bit ago and well its about a 2-2.5 sec lag before it jumps back in gear, TPS is 100% and all but its like nothing happens then bam... So annoying..
