Not sure where to start...you have some serious fueling problems, your MAF curve is all over the place. Timing is being limited with preignition cut ...

This is a basic LS2 with a single 7875 and you've maxed out a LS7 MAF in a 4" tube? Does that sound right?

As far as I know you can't change the duration of the timing pulled during the shift, so the solution is to make the shift complete before the...

Although it's really not recommended and I can't believe I'm even suggesting it - it is more tune-able or beneficial for you to just skew your...

Aren't those the LNG/LPG(?) injectors that are known to go weird when you try to put hot (relative to what they're designed for) liquid gasoline...

Yea. So I had my 18 Colorado v6 tuned and the dod was “disabled” but it still happened. So I found a thread/video (can’t remember) where it said to...

Here's a pic of the back, any idea which one is the culprit? Everything else works on the unit.

Purchased the MVPI2 anyway, I'm going to need it. I can sort out the PCM issue on the backend.

Could I possibly get a copy of the standard L86 A8 3.23 tune? I had mine tuned recently and they didn't save me a copy of the base file. Thanks!...

6,500 rpm is a hairr passed the power band. car should run quicker when shifting at between 6,000 and 6,200 rpm,... unless you have a different...

Your fuel cut-off is set to 6,400 rpm Also your trans shift scheduling / part throttle 1-2 gear your 75% to 100% is at 46 / 47 mph... i'd lower it...

Dropped the injector flow rate down to around 28 lb/hr . That brought the ve numbers into realistic figures. Re abled the MAF and added some fuel to...

I've read that once the tune is done writing, you want to turn the ignition off, open the door and wait about 20-30 seconds. Then start the vehicle....

thank you :pray: yes I know its a Frankenstein puzzle piece of vehicle. I will get a wide band asap I know it will be required. I will check and...

here is the updated tune. it did not like the other one at all so I went back to the 5.3 tune I originally had with the old engine. and that log I...

you wont find anything to drop in and call done. your going to have a hard time finding the right stuff in one spot. the engine parameters, cam...

I fired it up tonight and let it idol for about 10 mins until the temp got up to 140 or so. It sounded fine, so I think I got the seals back in...

hptuners does not offer the capability to switch tunes on ecotec's that i am aware of. Trifecta flashes an overlay file over the top which allows a...

you ever get bluecat to work?

These tune up very similar to Coyote. Increase TQ mgmt stuff, add spark in MPs, change target lambda, and on the trans you can increase shift...

ive been sitting on this for a day or so now and came to a conclusion on personal opinion for the scalar value. the second calculation i made uses...

I have a boosted LV3 as well, and I haven't found a direct bolt in 2 bar yet. A 12592525 is a 3 bar that will bolt right in place, and the Linear and...

Ill give that a try
