So just an update on this...

I found a solution in a reply to a different thread. Long story short, the difference between my Idle Spark Advance table and my Main Spark Advance table (in the...

This is spot-on!
I was having the same issue. I just copied my Main Spark Advance table and pasted it into the Idle Spark Advance table, and it alleviated my jerking/bucking issue SIGNIFICANTLY!
It...

Anyone have ideas?

I'm still getting an occasional P1515 or P1516 from time to time. Either when I hit the rev limiter or when I'm at very low MAP and low RPM (foot off the gas, coasting down a steep hill, in high...

Can you give me a quick explanation on how to do that? Are LTIT and STIT long term idle trim and short term idle trim?

Nevermind, I just watched a video explaining it.

I'm having the same issue. Hopefully someone that knows stuff can help us out.

Hey guys!
Having a annoying hot start issue.
If my car gets up to temp, then I shut it off for a while (5min to an hour-ish)... when I try to restart it, it will take multiple cranks.
I hit the...

I have a bucking/jerking issue at light throttle, low load cruise conditions (almost as if the car thinks I'm making throttle transitions.)
Initially thought it was A/F ratio related, but looks like...

I swear I adjusted the cylinder size once already... I wonder if I grabbed an older tune at some point and started using that without adjusting it again... :confused:
Does that mean my VE is going...

I've got a 2001 Corvette, that I'm having some issues with....

Details;
Manual transmission
LS3
BTR supercharger cam
Vortech T-Trim

Long Tube Headers
Factory O2s in both banks

I also had a similar problem with my MPVI2.

It worked for about a week, scanning and a several flashes... then it would intermittently loose communication. Tried different USB ports and it would...

I have a 3 bar (LS9) sensor in there now (you helped me with the settings for that in another thread). BTW on the MAP sensor, should that thing coincide with my boost/vac gauge? (IE 12"hg should show...

Hey guys!

Vortech T-Trim

Having difficulty getting her to start on her own.

Thanks for the advice! This issue decided to fix itself. I think that B2 O2 sensor was a little bit "fouled" if that's a thing. I drove it for a while and got it good and hot, that O2 started working...

Good idea!

The B2 O2 did eventually start to cycle (around 300-900) and it started running a little better (still needs lots of other tuning), but then every once in a while, it would climb to...

Hey guys my 2001 C5 with an LS3 and A&A T-Trim just got up and running...
Idle needs help.
B1 seems to be doing fine, but B2 is running rich. The ECM is trying to pull a lot of fuel from B2 when in...

I was under the impression that since my MAF is in a 4" duct, I wouldn't need to worry about maxing it out in terms of htz right, just have to scale the g/sec?
I found MAP numbers of 329.41 linear...

OK tuning gurus,

I've got a 2001 C5 Vette that I put an LS3 and a T-Trim Vortech on.
I'm running a medium camshaft (BTR supercharger cam), LS3 style card MAF in a 4"tube and an LS9 3-bar MAP...

I'm still not seeing a reply with my other email account either. I'm just gonna bite the bullet and purchase more credits. I gotta get this car going.

Is it possible that you can give me a brief...

OK, I forwarded my last email to you guys from another account. Hopefully, I can receive your stuff on that account.

Still not seeing anything on my end.
I assume you guys have my email correct because I got 2 messages from you already.
Double checked my junk folder...
Feel free to PM me here if that's more...

Yeah, I got the first automated response as well as his reply asking for more information (original file from the vehicle and an infolog) which I replied back with.
That was on Friday. I've been...

I submitted a support ticket last week (Ticket ID: 158682).
Corey replied back asking for more details.
I replied back with those details, but haven't heard anything since Friday.

I would really...

Any update on this?

I've got an LS3 ready to go into my 2001 C5 Corvette.
It's got a gold blade on it. Since LS2 TBs are sooooo expensive, I would love to make this gold blade work.
I'm not...
