I have had some quirky issues with getting my 4L80 to lockup as well. There are some parameters that we have no access to via hpt, I.e. "In order for the TCC to lock, the transmission temp needs...
Fixed it! Just needed to increase the Wall to impact Factor table a bit more. Yeah, that how-to was very informative (some of it was over my head lol).
Thanks so much for the help guys!
Thanks for the input gentlemen.
Well last weekend I finally went through all of your suggestions, and surprisingly, nothing seemed to make the hesitation any worse or better.
-I maxed out...
Yeah I know, I couldn't believe it the 1st time I saw that either. (I bought already built, tuned, broke-in,) The afr looks pretty good across the board (14.7 light throttle to 10.9 at high...

Hey guys, my Silverado (in sig) has always had about a half-a-second hesitation whenever I hit the throttle harshly. I say hesitation, but actually it falls on it's face a little and then the rpm...

Thanks again!!!
Got one in mind?
You guys aren't gonna believe this! PROBLEM SOLVED!!! I pulled the ABS fuse like DStech suggested, and the sputtering vanished! I even put the fuse back in, and it still doesn't sputter. ...
Thanks Mike I'll give it a shot.
DStech: I'll try pull the abs also.
10_ss: Yeah I have known about the pulsewidth split, but I'm pretty sure I have encountered the sputtering several times,...
Thanks for the info Mike, I've been working on dialing in the MAF only, this week, and finally started to ease into boost today. Started rich of course and leaned out to where I wanted it.
But...
Lol, that's what I thought, until carlrx7 said "VE and Maf are both enabled, tune one then the other.", maybe I am interpreting his statement improperly though.
I guess if I knew I could take it...
Thanks Carl, I just spent the evening tuning the MAF with MAP unplugged. It was not very cooperative. Very difficult to tune in boost, maybe it's my Delphi maf sensor. I got it as close...
Well I have spent most of weekend working on this thing. I bit the bullet and licensed that tune from DStech. I thought about copy and pasting, but I was kinda concerned that the tune might...
Well I hooked up the MAF and it started out great, but it had it's own set of problems. I got it dialed-in from the bottom end, up to heavy throttle. As I got up to heavy throttle, the fuel...
Hey guys, I appreciate all the input! Cash talks I guess! lol I combed through you guys suggestions and I'll try messing with it a little tonight. I'll probably post again tomorrow.
...
Hey guys, I'll send $75 (via paypal, or snail mail if you prefer) to the first person who can tell me what needs to be done to fix my sputtering problem (after I see that it fixes the problem, of...
Anyone?
Finally I'm getting some clues!!! Since I've been getting nowhere, I decided to go back to my 1bar map and tune, even though that's how it was setup when this whole problem started.
But...
This weekend I finally got a chance to try what you said. I got the STFT's looking a little better, then I swapped coils, then injectors. The problem seems the same and is still on bank 1. ...
I finally borrowed a fuel pressure gauge and here is what I saw: Pressure was rock steady @63 psi during regular driving, but when I got into boost where the engine starts to sputter, fuel...
Well I don`t really have much faith in my "sotp" testing abilities, but I do know that running the most timing possible without detonation is ALMOST always going to mean more power. Plus or minus...
I couldn`t really tell a difference by the "seat of the pants" feel. Last night I continued the saga of raising timing, and got to 25 deg (24.5) and still not a even a blip of knock! I still...
You're right, sorry. Here are some more details: IAT around 105 deg, WOT from about 3000-6000rpm, 10.9-11.4 afr, ported 243 heads, long tubes, no cats, hooker muffler. I do not know the CR. ...
