2006 Mustang GT auto - U7140 r.35 - JLT Cold Air Intake

[mikel]

does it do it with the stock tune as well?

No. Stock worked no problems.

Started when I loaded the first tune from the predator.

-- First tune was 87 performance when I had stock air intake and 87 fuel. It started doing it. I though no big deal I'm adding JLT intake soon...

-- Then when I was on empty, I added 94 oct and switched to JLT II intake and loaded JLT 91 performance and bumped global timing adder up 2 degrees. Still does it but more noticeable now because of extra power.

Searched this forum and found this thread. It describes my symptoms perfectly.

Anyone know what Cole did to fix it for rpettit?

[mikel]

whatever cole did (5 years ago?) was fixed in the newer revisions....

post up your backup and last tune written files from the tool please.

Hi Mikel

I posted them in my first reply to this thread. Let me know if you need anything else.

Hope you got my tunes ok.
I was doing some data logging this weekend. I have no idea what logs might help but thought I would drop this in here anyway.
You can see just after 3rd gear it bogs down. A little cooler today and it doesn't seem as bad, hardly noticed from 1-2

Looks like agingtech reported the same problem here also: http://www.diablosport.com/forum/viewto ... =9&t=40464
I pm'd him, but he hasn't had time to send the logs but says he still has the problem too.

Hope this helps.

can you please simply repost the tunes here so I dont have to send our ford tuner digging all over the forum to sort this out for you?

Thanks

Sorry I thought it would save time by posting them in my original reply above.
Here they are again.

[mikel]

Try that and see what you think.

Ok, bog is fixed. But not a lot of power... Is this a 87 tune? or detuned a bit?

[sohfast94]

One more time.

[maverick214]

One more time.

Thanks for your quick replies sohfast94!

Tested.
It's not as fast as the JLT 91 tune doesn't seem to pull as hard, but no bog.

Is it 91? If it's 91 I can run 93 and boost the timing.

[sohfast94]

I didn't change anything to do with the performance of the vehicle.

Ok so is this still a 91 jlt tune?

[mikel]

its based on whatever you posted as last tune written...if you want to set it up for 93, add 2* of global spark...
