It wouldn't run for crap even with the codes turned off until we put the vats module back in with the correct key and the bcm. It ran, but misfired randomly, even with the codes turned off.

I am having the exact same issue. It's an LS7 in a rock crawler equipped with a th400. Once it hits the rev limiter, the throttle drops to 40% unless you let off and re-apply the throttle. I am...

I have had several V6 3.8 FB both auto and manual trans. It was necessary to install a vats simulator for the engine to run.
VATS will not disable in the ecm. The engine randomly shuts off...

I think there is something in the tune that HP Tuners does not give us access to. I had a 2011 Camaro LS3 A6 tune that the speedo works perfectly, the vehicle speed output is set to serial and it...

part # 12614973 shows as a stock LS1 99-02 FB 1 Bar map sensor.

Looks like we will just have to try the 60 lb injectors and use the rising rate fuel pressure regulator to keep the afr's in line. We will have to pull timing from the 105 kpa parts of the table and...

I'm sure we can physically make it fit, the question is.. has anyone done it or tried it? I'm assuming the transmission tables would all have to be rescaled to maintain pressures. It will need...

Any way to turn off this code? I've had a couple of cars that I had to convert to 2006 LS2 Code to get to run... not ideal...

A friend of a friend is looking for a tuner in the Dallas area. It's a shop that has done an LS install using a Paul Newman Chassis and he needs some help with idle. Please send me a message if you...

I have tuned several of these and I had to do a re-write complete vcm everytime.

All vet's Brake Control Module expect to see about 5/8" taller tire on the back than on the front. There is no work around in the software. You could buy a speedo signal conditioner from Speco, you...

A friend has an issue.

EVERY time I program a 2006 CTSV I have to do a complete re-write.
But first you need to put in the VIN. GM shipped this things with NO VIN in the PCM. Put in the VIN, then you need to do a...

Your VE Table is way off. You need to datalog commanded afr vs actual to see the % error. You need to smooth your ve and spark tables.
When you have your ve table right, there will be no...

Many Forced Induction setups have the PE Enable TPS set to 19%. You want to be in PE before you go into Boost.

Log your commanded afr next to actual afr. Reduce your PE enable down until it's always in PE if necc to figure out why it won't go into PE. There has to be a reason. Turn off Closed loop until...

It is an E67, says it on the case. I'm afraid to try to write it because it's the only one, I don't...

2007 Explorer 5.4 with 6 Speed Auto Support? Any idea if/when you might support this application?
Mark

We usually talk about compression ratio's and use the static compression as the benchmark. Dynamic Compression is what the engine sees and is calculated by when the exhaust valve closes. Here is a...

This thing was really a challenge to dial in. I had to raise the failure rpms ffor the stall speed. Also did the auto scale, then put the tire height and gear ratio back to where it originally was....

When I look at your datalog, at 2209 - 2250 the only time you get cross counts is when the short term fuel trims are -21% to -26%. So it looks to me like you are quite rich. Have you installed...

Cat conv readyness and evap readyness go to yes if you turn the codes off.
In street rods I turn off the appropriate codes so they don't turn on any annoying lights and the status sensors go to yes...

Changed the Idle, idle airflow effective area failure settings. No longer goes into reduced power. Starts right up! EVERYTIME!
