The Holley wasn?t bad for drivability but it?s not the OEM in terms of addressing just about any condition.

What brought me back was:
Durability and Warranty, If the Holley PCM goes your out...

Thanks BS, that helps validate whats going on.

I tried Holley and decided to use OEM/HPT for this build. I'm looking forward to using OEM/HPT again and not afraid of digging into some tuning....

So I have a tune from a cammed 6.0, building a replica combo ( accept I "need" to use a LS1 style FAST 92mm intake vs a truck intake, yes I know but wanted to hear about fuel first) and I'm planning...

Guess I'm being stubborn and stupid at the same time.

After a few runs I didn't get too far with eliminating the lean spike on PE/BE transition. I'm pretty sure that condition was not present...

Certainly not a MAF expert but I'm gonna run a MAF. This is a daily driver and I'm shooting for the whole experience. I get there are tons of guys running SD out there and super happy with it but I...

Thanks for the PE tuning tips. I just added them and will check it out tomorrow and see if it helped the transition lag in PE/BE.

I went with conservative timing and will get after that in a bit,...

Working thru tuning my Gen 3 turbo 2 bar build.

Failed the MAF and setup OL
Tuned the VE tables to a reasonable point up thru ~10psi (street tuning)
Flipped the MAF back into play and left it in...

Just read the link,

Never mind that spark question!

I have a MAF.

I have the idle in the ballpark VE is +/- 5% in the 60kpa/800rpm column @14.3 AFR, holds pretty steady around 925RPM.

To get it running safely is it just repeated test and learn...

Learned alot yesterday, primarily how to use the scan tool!

went back to stock VE
Idle rpm to 1000
set advance to 15 degrees thru idle range
turned off STFT

I also configured the Russ K...

Should I revert to the stock VE or should I start with what I have? note: the stock VE required me to remove 30% just to get it to fire.

Put a 4.8 together with a cam (585/585 228/230 112) and SD80's. Has a 2bar map installed and the Turbo is plumbed but charge pipe is open so I can get it running. I'm a first time efi tuner using hp...

I'm starting to think that the additional channels I saw were user defined some how? I guess I would have thought something like IFR was standard?

Hey guys,

Real new to this and searched for what I thought I needed but didn't find what I was looking for. I recently started working on a swap using a 4.8 liter with 4L80E out of a 2004 Chevy...

My friend has a 2009 VCM Suite standard and I'm thinking of buying it since I want to start getting into LS1 Swaps as a hobby. He used 2 credits to tune his 2008 Pontiac Soltice GXP with it and it...
