Working on getting a read from my 19 grom, waiting on adapter. I'll post tune when I can.

Wow! Never heard of any thing like that before, I believe the hour meter is stored on the eprom of the guage cluster along with the mileage maybe a loose connection at the cluster or failing eprom or...

The VE and the MAF work together, you need to tune the maf as well. Put it in maf only mode dial that table in then turn the VE back on.

I'd start with in gear idle tuning, should be an idle tuning guide posted here somewhere.

Okay guys so I've added Snake Eater 850cc injectors to my 2008 Silverado 1500 RCSB 5.3l Auto Flexfuel truck and I want to make sure I've done the math correctly.

Factory truck 105k miles. Planning...

I'm looking for the same...

I changed the speed limiter and added 5% pulse width. That's it.

Old thread but better late than never. I ended up adjusting the startup airflow and the truck runs great now, no check engine lights at all.

Ok, I had some free time this evening so I've made the values the same throughout the entire table and I've set flex to disable. I've taken 3 logs after clearing long terms. My long terms were very...

I've tried disabling flex in hp tuners and setting default to 5%, but I still had high negative trims with it disabled. So that's why I went the Tech2 route and reset the ethanol content. I cleaned...

This truck doesn't use a physical flex fuel sensor, it uses a virtual sensor.

2016 f250 Same issue minor changes and p167f DTC thrown. Any update on this?

Ok, I picked up a 2008 Chevy 1500 RCSB 5.3l Auto Flex about a month ago. I plugged in and found the ethanol content @24% and LT fuel trims approaching -20 on both banks which is way too high, I ran a...

First thing I notice is your engine size is incorrect in the tune file it should be .875 for a 7.0l ls7, Second thing I see is your minimum injector pulse is @ 1.261 which seems pretty high to me....

Probably too new of a vehicle, its not listed in the supported vehicles list. I get the same message on a 2018 Fiesta 1.6l Non turbo also not on the list...

In log "test 13.hpl" your B2S1 02 sensor isn't reading correctly or you have a massive exhaust leak.

Speed limiter lol wow, I saw the ETC set to 256mph figured the other tables were maxed as well, that would explain the TPS reading dropping, thanks for the update!

Your offset is incorrect, your flow is correct, your short pulse adder is incorrect, the min injection pulse deatsch werks recommended is wrong. Maybe you're looking at different injector data than...

Those logs are all over the place, I'm seeing 02 reading all over the board something is way wrong. you need to enter the correct injector offsets, injector data provided doesn't match tune.

I'm still learning this but just looking at your log I'm seeing your tps beginning to drop @ 5750rpm shortly after you move out of the WOT shift tables into the performance table. By this log I can...

Your minimum injector pulse width is at .727, try setting it lower to .400.

As far as I know Edge like HPtuners is going to use a proprietary file format for logs and tune files, so yeah your S.O.L tell MPVI2 arrives.

The all "yyyyyyyyyyyyy" issue can be resolved if HPtuners prompts you to enter a VIN during the read process, however I encountered a 2004 today that didn't display anything in the VIN and didn't...

Ok, I got to play with the truck some more today. I really bumped up the startup airflow from the 3.0g/s stock to around 11.0g/s the truck fires right up now when warm and idle's well. Only issue now...
