this truck has the TSP 225/231 .631.631 112 lsa cam

I have the idle set to 750 when warm. This truck will exibit this issue when starting cold before getting to operating temp and also when warm.

2014 GMC 1500 6.2 SWAP
TSP CAM. AND BOLT ONS.

Truck runs good cranks and idles fine, makes great power. Has one issue when starting and making small throttle inputs in gear, the truck will die,...

bump

Looking for a fresh set of eyes on this truck. We pulled the 5.3 engine out and installed a 6.2 long block which we pulled from a 17 Camaro. We equipped the truck with a TSP camshaft, L86 intake and...

NO TAKES?:pray:

OK Very very new to the Gen V platform, so I had a reputable tuner send me a mail order tune for this truck. We installed a TSP stage 2 cam, 218/226 .635/.635 113/109IC, AFM deleted, ls7 lifters,...

SO if Fast injectors require fudging is it that they dont flow the flow they are rated or do they flow more than they are rated; just asking . If i had a constant in the MAF then it would be easier...

OK
I disabled VE table and made some other changes to perform some MAF tuning, and after pasting histograms I come up with this scan and tune. Does this look like an acurate account for the MAF...

I dont know what the reasoning was for that, I never actually touched ANY timing tables yet, they are from the starter tune I recieved. I really never paid much attention to that.

And secondly:...

The truck intake doesn't take the short injector, it takes the LS2 style injector. The information from FAST was that they flow 46#/hour at 58 psi, and so I need to change the enable to 200 rather...

Thanks for that info, I will report my findings.

Gonna go out and try this out now and see how far off it is using just the MAF calibration, with the injectors entered in correctly.
Timing is scetchy still because of a somewhat high dynamic...

No One Has Any Ideas Or Help

I inputted the fuel injector table to be correctly represented for the injectors installed, and added 20 percent to the MAF table and got this to get the LTFT's closer to perspective, but have now...

Ok, Here is a rundown;
I have a 08 GMC Denali truck, that I have made some changes in the setup, and they are giving me hell. Here are the specs:
LSX block with scat 4.125 stroker crank, rods, and...

Hoping that with these I am moving the point where I will have the IFR maxed will be out of the fuel pressure range that the truck will ever see.
Maybe wishful thinking!

So when tuning, do you tune for the rail pressure or for the inj delta pressure, when setting up the IFR table, maybe that is the problem. I am actually pulling some injectors out of an engine that...

Oh I see. Well first, that's the incorrect method to go about tuning those injectors. You leave the tables alone for fuel pressure (stock). You then simply cut the IFR table in half (50%) and double...

What I am attempting to do is drive the fuel pressure at a constant 43.5 all the time, since the injectors are rated at 60 lb @43.5, and anything above 63.5 my system will not allow me to input for...

I am not professing to be an outstanding tuner, I have a decent grasp of the basics. To my knowledge best, I have attempted to reduce the fuel pressure in the fuel pressure sytem area to run at a...

NO ONE with an answer to this. I still cannot understand why with the truck commanding a fuel pressure of 43.5 it is still running on the scanner 51 ish. Would this be the recommended way to control...

This is the tune and log from where I am attempting to control the fuel pressure at a constant 43.5. Hopefully it helps you help me!

Ok just tried to another attemp at driving the fuel pressure at a constant 43.5 and after datalogging it looks like it is commanding a 43.5 but pressure is still around 49-52 reading from the scanner...

I have a 08 GMC truck with a 427, and I need some help with the injectors. I purchased a set of 60lb injectors rated at 3 bar for this engine, and am having trouble geting the injectors right in the...
