Really? I thought it didn't matter what kind of fuel you used when tuning the VVE and MAF as long as you had a actual ethanol sensor installed and enabled in the tune. I did however top off with 10...
Yeah, I always assumed the sensor was more accurate than those test tubes. I put 5 more gallons of 93 in this morning and it brought my ethanol content down to 17%. I just know that my fuel trims...
I've been working on getting my tune dialed in over the past month or so while running pump e85 and had my part throttle fuel trims within 1-2%. My ly6 gets a lot of spark knock on 87 so its just...
Update- Downloading the latest beta version and I can open that.
Just recently updated to 5.0.4 and now when I try and open the editor I get the vcm editor has stopped working message. VCM scanner works fine though. Running windows 7 Professional and a 64 bit...
Thats what I don't understand. On the 2008 and newer e38 pcm fuel trims cells 0-7 are evap purge on. Fuel trim cells 8-15 are supposed to be evap purge off. If I use the filter [6310]>7 (only allow...
In the middle of trying to fine tune my MAF and VVE using the GMVE method and I'm having a issue understanding fuel trim cells and when the purge solenoid should be open or closed (EVAP purge messing...
When trying to submit a support ticket I keep getting a HTTP 403 Forbidden on the next page. Any idea what's up with that and why I cant create a support ticket? After updating to 5.0.4, I am getting...
I tried doing that but I didn't notice anything. Is there any special procedure?
I'll have to check but I did try replacing the throttle body with another used one I had laying around but that did not help.
I swapped a stock 2009 ly6 into my 2011 GMC Sierra and I am having a issue with a higher than normal idle (commanding 600 but its idling at 800-1000) and I am seeing near zero timing when its in...
Unfortunately I have spent the 4 credits to license both vins but it still for some reason wont take the vin. I have tried it every which way I can possibly think of. I tried changing it through the...
Awesome, thanks!
When swapping a pcm on a vehicle, must I license both vin numbers or can I just license the pcm I'm swapping in and then change the vin to match the vehicle? I'm having issues changing vins on a e78...
I purchased 2 GM credits because when trying to flash a vehicle it said I had zero credits. After purchasing two more gm credits it was now saying that I have 10 GM credits under my devices when...
Hey guys! I'm looking for some help setting up filters when street tuning running open loop and using a wideband. I would rather do one long log containing both part throttle and WOT runs and then...
For anyone wondering, it was the MAX FAIL under the effective throttle area in the idle airflow tab. My guess is when you fail the MAF it defaults to these maximum areas at idle. I doubled the MAX...
Can someone take a look at this log and give me some ideas on where to start. It starts fine once up to temp but cold starts with the MAF failed are surging real bad and I'm having to give it some...
I've actually wired in a ethanol sensor so the virtual sensor has been disabled.
Also, here is a copy of a older tune of mine when I had a shop tune it. This was running the older operation system if you wanted to compare the two tunes and see the differences between the two. I...
Will do. I haven't seen it start pulling a ton of fuel yet but as soon as it does, I'll post a log.
Yup. My operation system didn't have the 2 bar SD option and I was tired of messing with the VVE. I could never get that thing to do what I wanted so I found a OS that was supposedly compatible with...
So I drove the truck again today. I stopped at a gas station to re-flash the truck and I took a before and after log. There is clearly a good 20% difference in STFT's before and after the re-flash of...
They are.
I should have probably mentioned that it is a return-style fuel system with a boost referenced fuel pressure regulator and the fuel pressure control module has been removed. They are Fuel Injection...
