Well, I was hoping to have screen shots & everything to prove the fact but will have to wait for me to update this tomorrow...

but a couple of months ago I tried using the VX L67 enhanced file to tune a car on the dyno & couldn't get my head around the change over point & wasn't gaining power it was just a lot of heat soak...

... last time I put a new bigger throttle body & Gen3 MAF on the vehicle & picked up a heap more torque down low but lost top end power & thats serious, I tried everything made it rich & still had to pull timing & lost torque down low so leaned it out a bit & run best min & had to let it go...

... I had another chance on the same car with more mods....got the vehicle back to fit a insulator & cooler thermostat & it had water injection in between which stuffed with the AFR's a bit but tuned it up this time & got the changeover point sorted for the enhanced file & gained 20rwKw with not a hint of detonation & had AFR line flat as where I wanted for best torque & obviously got the power up top!

WHAT THIS SPACE I WILL UPDATE SCREENY's

Screeny's...

cool! 1 degree makes a big difference at the top

Yeah it certainly does on the FI systems, you might notice the 1 with det has 10% more air & this is due to being on the road open air & morning so fresher & dence!

But still results are on dyno & got fuel line flat & 100% to commanded!

Not bad for a gen3 maf on vehicle it's not made for big thanks to Yoda for help there with making it scaled to 12 instead of stock 8!

does it break 10000hz? atleast the larger maf will help with flow though.

So we have extened spark on the flash PCM's now aswell?

atm only on S/C pcm's vt-vy
