How accurate is the Delivered Torq-Eng PID

[mustbbrent]

This vehicle being an AllWheel drive has never been on a dyno. I was, pre-turbo getting about 321 at the maximum from the Delivered Torque - engine around 4200RPM. With about 10psi boost, I am seeing 578 Delivered Torque - engine at 4400RPM. And this is not just at a shift point. These numbers are all near the 4000rpm to 5200rpm areas.

Can this really be right? Gaining 256lbft of torque @ 4000 rpm is 195HP gain. Most 1/4 mile calculators show that I am about 410 FWHP with my old 1/4 time and and 425 FWHP with my MPH, making this somewhere near the 600FWHP mark. Surely I am missing the mark somewhere, right?

Huge bump.

I heard somewhere that delivered engine and delivered trans were both surprisingly close to actualy power at the WHEELS, but your numbers there are HUGE gains that make me skeptical...

I'm looking to find out how accurate it is also. Our motors are supposed to make 380ft/lbs at the flywheel, stock. The most I scanned with cam, tuning, all that stuff was about 350-360. After installing headers, I'm seeing gains of 40-50ft/lbs.

I hope it is accurate. I typically see 400 ft-lbs logged, and on cold days I see as much as 427 ft-lbs. Woohoo! I am anxious to hear the answer about how close it is. Particularly on a MAFless tune like I am running.

how are you guys logging your torque?

[marc_w]

In the scan tool, under the table(?) display... I remove one or two things I don't wish to scan... then I right click, go to Engine, Torque Management, and click on the Delievered Engine Torque...

That pops it into the table display.

With V1.5, you can now chart it... The old way I'd check it out would be to export a log to .csv...
