^^^ What he said.

Cool. How close was the table?

Checkout the fuel tables I posted a while back. http://www.diablosport.com/index.php?na ... ic&t=27915

To get from 11:1 to a more ideal 12.15:1 you need a fuel adjustment of -9.5%.

The only difference between 91CAI and 93CAI is +2 degrees at all three ranges at WOT.

I find I need more enrichment the lowest rev range. Be aware that any knock in the first range may "linger" in to the mid and upper range. Look at the chart, work on the range that the knock first appears first ...

???

Yeah, try adding more fuel. You have not added much. I am at +14%, +12%, +12% with my tune! You might find you can leave spark at zero once fuel is right, assuming lean running is the cause (often is). Increase to 6% then try 9% - 12% until knock is gone.

0101 is Mass Air Flow fault. Can't advise on that, but it's a good idea to pull the engine fuse after loading tunes to clear the adaptives. Some people have reported other weird issues after loading tunes without resetting the Engine management computer.

I am running 93 CAI tune, I removed the Helmholtz resonator and also the front vent blocking plate, although I use the stock paper filter for now). Much cooler air.

Go in through the guard in remove the blanking plate behind the vent shown here:

you can compare the files and see

simple timing change...

Hi Mike,
How about sharing the details with us please?

Yep, you got it.

Makes you wonder why the 2 sets are provided if they must be the same...

Perhaps one of the gurus can explain further?

My 07 300C with the same tune does this also. If you go for half throttle initially, and then floor it once above 4000rpm does it help?

I suspect this is torque management at play. I can see on my logs the bog just after the initial lunge.

Thanks. I am already running 93 CAI with 2 degrees out across the range, but still suffer ST, mostly at part throttle.

My fuel is at +8%, +12%,+12%.

Hi, my Predator u7135 shipped with only 93 tunes.

Can someone please post up both 91 tunes for me please?

I am running 9r28.

Cheers.

And you have not dialed in more fuel?

The latest Predators don't support 9r12. I too experienced this. You need to install 9r28 using the instructions here: http://www.diablosport.com/index.php?na ... ad&id=3944

'click here if tool says application missing or corrupt' is the answer.
