I have a 2012 Ram 5.7. I made my scanner histo as showed in one of the stickies. It's not Populating but part of the Fuel mass vs Inj data. Most of the time it stays in the same box. I still have NN...

I see what your saying on it pulling timing in shift points, just haven't seen it logged in my scanner like that before.

Thanks again for your...

I set stoich back. Where are you saying to pull the neg timing from?

there is no knock retard showing in my scanner at those places. Only those massive dips in a few spots . It doesn't happen all the time and I've been logging every drive. That just seems like alot of...

LS1, speed density, mild cam, 11:1 compression, truck heads n intake, 36# injectors and shorty headers. Everything else stock. I'm having a weird issue where my timing drops way down in a few spots....

Go to the desktop sight and its easier to upload documents. On the reply to thread box, click Go Advanced, there is an option there to upload

Sorry didn't see the post about the vacuum referenced regulator. It has a vacuum nipple on it but I didn't think I should use the vacuum port since the returnless systems don't have a vacuum ...

I got a 99 Vette tune from repository. It doesn't have as many adjustments. Mine is an 02 Fbody OS 12212156. . I may have forgot to change vin with TP and pcmhammer when I originally set this ecm...

The stock tune was supposed to be from 2000 fbody LS1. It seems like everytime I flash a new tune, more stuff changes I didn't even touch. When I switched to the HPT OS to run SD it starting showing...

No vacuum hose.This system doesn't use vacuum to regulate pressure.

Current tune.

I fixed the surge. Issue was my Corvette filter/regulator failed and had my fuel pressure way too high. So I bought an EFI adjustable fuel pressure regulator. It's mounted on the return port of the...

Recap: LS1, 212/218 114LSA cam, 11:1 compression, headers, truck intake and stock throttle body.

Went from return style system to returnless.

New fuel cell, 255lph fuel pump, new 6an lines,...

My new fuel rail does not have an FPR. It's a returnless. I've switched to the Vette filter with built in FPR. No vacuum referenced FPR on the system now.

Could you post or pm the data for the new injectors. 12580426 is the number on the inj.

I about to bolt the tank back in and run the new lines. Hopefully get it fired up tonight.

I used RussK idle tuning config to dial in my friends cam at idle. Google the RussK idle tuning and you will find more info.

I messed with the rails last night. I pulled my return off the tank put it in a gas can and my fp dropped to 62psi. I then pulled the rail off the intake with injectors and found I've got 2 injectors...

Thank you for the info. I didn't even think about return line restriction. I'm gonna drop my tank tomorrow and see if the return line is bottomed out in the tank. I'm almost positive it's against...

Sorry it took so long to reply to you Hoandaeater. I just got around to checking fuel psi. it's at 70psi with and without vacuum line hooked up to regulator. I'm kinda at a cross roads here, I was...

I'm using a return style truck rail. I will have to check my fuel psi this weekend. Honestly I havent checked it at all. I'm using a stock jeep efi 4cyl pump. Which is supposed to be capable of 78psi...

That's what I had set them at to get the cam to lope a bit . Info was from several YouTube videos. I will tone down the over/under. I didn't have a high idle till I started dialing in the VE. It...

I see I had turned off reporting the maf fail. I fixed it that part.

@hondaeater
It has a maf but I set it to fail so I can just run SD. Stock throttle body with 3.5" cai. The only reason I haven't completely removed the maf from the cai is because IAT is built into...

I have an 01 LS1 with truck intake , mild cam and shorty headers. It's in a jeep and not tuning any wot until I get my wide band in. I am tuning with SD using the hptuners custom 1 bar OS. I did my...

Its a shudder when it hits 4th gear. Only under light/normal acceleration. I raised the tcc partial apply but it just barely made a difference.
