Your idle timing should be around 14 degrees with that cam. I usually set my Minimum spark to 14 degress in the first 3 columns. Max your torque delta and torque delta tables out in the engine...

Copy these values in the engine diagnostic tab. Should make your 3k limit go away

My fuel pump wasn't pumping enough pressure. My own DA attack, I can share my current tune i've been working on to give you a good starting point.

Im not looking for an easy way out, this gen 4 stuff is new to me and im wanting to learn it so I can do it correctly but im not understanding what exact offsets and coefficients you are talking...

I have the proper offsets, im using the red map sensor with the correct offset. What other offsets/coefficients are you talking about?

This is the tune that was in it.

Second tune is using the ctsv spark advance table, ctsv map values, ctsv scalar and throttle body settings. I have the FIC injector data in and the E85...

It is a GMPP crate LS3, I figured it'd be an easier starting point to use the VVE table from a CTSV to start with than the one it had in it.

Figured I would update what fixed the issue. The cam sensor was bad, we replaced it and it fired right up on the Stock OS tune I posted above.

I wrote the stock OS back into it. Here is the logs I tried and current hpt file. Im getting no inj pulse. I dont understand whats going on here

Ill flash the original OS into it instead of the 2 bar. Can you see this file?

I've never messed with a gen 4 before and im having issues getting a SC'd LS3 swap we just finished to startup. Its commanding a 1.8afr on startup on E85.
Any help would be appreciated. 2 BAR sd

What do you mean what was my original tune? Its an E67 Ecu from a LS3 crate engine kit from gm. It was tuned for the hot cam. He wanted a lsa sc so we installed the lsa on the engine and now I need...

I upgraded to the 2 BAR OS so the VVE table isn't there. I did find the IMRC tables, they are all zero'd out so I am trying to input numbers from the VVE on a LSA tune into them to form a table to...

Awesome, thank you very much!

I dont have a VVE table to tune on a ls3 VW swap with a LSA SC on it. Where do I tune the VE on this?

figured my issue out... post can be deleted

Swapped a 5.3 into a 86 square body. Still has 700r4 behind it. Im trying to get in started but its just firing and not staying running. Trying to figure out what I am doing wrong here. P59 ecu, tbss...

Just curious what others run for AFR on there two step/launch control? Also what timing are you running and how much boost do you build?

I am at 15-17 AFR with 19* timing at 4300 rpm at 105 kpa....

It is much better, a lot smoother now also. I figured out that I need to scan inj PW to see my inj duty cycle so now I can get my PE and boost dialed in. Thank you

Im gonna go try this out, should be far better than I had

I could swear that my map sensor data is exactly was he said to set it as.

Its a 2.5 bar map from Dsteck, wow my boost VE was completley off... :confused:

Thank you 👍🏻

I had the tune scaled 50% for bigger injectors since I could not get the Double stoich Half IFR trick to work. I switched injectors to 96# deatchwerk and with the correct data this time I was able to...

Here's my story. A couple weeks ago my buddy bought a modded 2006 pontiac gto (bigger cam, intake, exhuast, etc) and asked me to tune his car. I hook my hp tuners software up to it and do a Read...
