I got a SCT tuner from VMP and they could not tune my gt 350 TB so I had to put the stock one back on I have it tuned on e-85 with the stock TB and it runs ok but I?m wanting to switch over too hp tuners can I keep that vmp tune or do I have to go back to stock and start over ? Please help already wasted enuf money
whats your strategy? which VMP tunes did you purchase? Justin did alot of testing with the GT350 manifold and TB, so i am not sure why he couldnt tune that combination that is very interesting to me.
Also, I would like to mention that we do not recommend the GT350 throttle bodies due to known issues with surging and stalling - these concerns are not something that can/will be addressed in the tune file.
We can write the initial tune for the GT350 throttle body, but if you experience an issue that is thought to be related to the GT350 throttle body, we will recommend installing the stock throttle body, and using an adapter plate to pair the stock throttle body with the GT350 intake manifold: https://www.vmpperformance.com/VMP-G...-adapter-plate.
A $49.99 custom tune update will need to be purchased to have the file updated for the stock throttle body.
The stock throttle body will offer more desirable drivability, and there is not a significant power difference between the stock and GT350 TBs.
can you post you tune file or strategy off SCT device?Originally Posted by Smokinrob
it wont attach
me tuning e85 hp tuners having problems getting the 02 sensor bias set up I got it too work with the f150 set up adjusting for e85 but had a target n issue I tap the throttle up past 1,000 rmps it goes up to 2,000 on its own and stays there every time I reflash the cal the o2 sensor are not working stuck on lean takes changing the bias to something else and reflashing get it working but as soon as I flash another change right back to the same problem
So you have Gt350 Intake and Throttle Body Installed, any other MODS besides E-85?
2016 mustang GT
Gt 350 cold air intake
I took off the gt 350 Throttlebody and put the stock one back on
I have a stock manifold
Bbk long tube headers
Straight pipes all the way out no Cadillac converters
MGW sort throw shifter
do you still have your SCT Device?
Yea
[QUOTE=Smokinrob;679748]Yea[/QU]
I can try and send you a file to try utilizing the gt350 TB, but i would need the X4 serial number..
I would like too just figure out this hp tuner and just move forward with that
Anybody?
ii understand thought i would offer, so to fix your tune you will need the MAF Period from GT350 File, Multiple O2 transport delay & Time Constant by 1.10 or 1.15 to make up the time from stock manifolds to LT header.

Did u look at my log and tune I posted about the target N
your LTFT off by 29% and multiplying maf flow by 1.29 should solve your issue
Witch problem?
I cant even get the e85 to work this error is all I get

I missed that part of the conversation but as Small Tuner stated you MAF out of whack.
