I've recently started to work on my truck tuning and am running into an issue where I seem to be chasing my tail, so I'm sure I'm missing something. I've attached a short scan during initial...

I?m not positive, but I believe DSX Tuning sells the upgrade as a direct drop in/ PnP 2010+ ECM. I?ll need to confirm. I also have access to a Tech 2, but I?d rather have someone do it right the...

Thanks. I am likely going to upgrade to the 2010+ E38 ECM to avoid having to scale airmass tables, if I can help it. That would give me some room in the flow rate tables to do the double stoich...

It sounds like if I lower my base pressure (to around 43.5psig) I may have better luck?

It can be done. My brother has an F1A-94 car with 1650s on the stock ECU

Yes, I plan to switch back and forth from 93/E85.

I have my flow rate vs. press all set to 58lb/hr. That's what I have my regulator set at. I also have my Offset vs. Press vs. IGNV with each...

I was planning to do the double stoich method, but my ECM only will allow 127lb/hr. Half the flow rate would be about 86lb/hr. I was looking at doing the 2010+ ECM upgrade to be able to do that. What...

Installed new Fuel Injector Connection 1700cc injectors and used the injector they gave me. Set my regulator to 58psig, but I'm not getting the car to start. I'm guessing it's because I have...

I lowered the MAF about 15% and it has seemed to help the surge for the most part. Something I thought of while loading the tune was that when I had the initial tune done by MOT he didn't use the...

I'm not sure, I had thought it was accurate though. My assumption was that the 5.3L was 323.426 CI which would be 40.4282 CI/cyl.

Thanks, I'll start with that then. I was hoping to avoid rewriting the ECM until the emissions checks show complete and I pass the emission test, but I suppose a little better fueling will help...

I've recently swapped in a 5.3L SBE with a Truck Norris cam, BTR .625 springs, VSR 80mm billet turbo, forward facing headers (wrapped), FIC 850cc injectors. Truck is a 2013 Sierra 1500 Denali flex...

Sorry...ITT?

I have 850cc injectors from Fuel Injector Connection installed and I'm at a loss as to how to apply the short pulse correction data tables into my tune file. Could someone look at my tune and guide...

OK, I guess my next question is how would I go about adjusting the tune to let the truck idle so I can start working on the VVE table? As a side note, this tune is from a supposed reputable tuner...

I won't say I'm 100% sure, but it was a stock 3 bolt cam. I thought all DOD cams were single bolt? Or am I thinking of a VVT cam? I may just buy a new aftermarket cam and install it to rule that out.

Thank you for the replies and sorry for the delayed response. I've been busy with work and haven't really had time to work on the truck.

I swapped in some NGK TR6s a couple of days ago. The truck...

Hello,

To preface, I am not claiming to be knowledgeable with tuning. I know the very basics and how to navigate the HP Tuner. That said, I recently began experiencing an issue with getting...

What is your PE ramp in rate?

Are you logging throttle % in your scans? It's not coming up for me. Looks like a forced induction setup?

Loaded a file with "sensor" selected and the ECM seems to be reading accurately now. Thanks for the simple fix tip. Everywhere I've seen everyone had kept "virtual" selected.

I'll try that later today. Thanks

I installed one of Innovate's Ethanol % gauges and it's been working properly (I have to believe as it ranges from 7.5-10% on 93 pump gas). I have my signal for the PCM and gauge using the same power...

Thanks for the reply. Is there a way to scale the signal voltage to manipulate the output?
