Ah. I thought those were more a matter of clever settings.

i bet vishnu tuning can set you up. they already managed it with the vortech. may as well get the whole setup from them since you have the oft already. As far as I can tell, the only actually bad setup is fa20club.

What, you don't like running ~stoich under full boost?

So I think I know the answer to this question from sporadic reading of this thread but I'll ask it here anyway in hopes one of you wonderful smart people will confirm...I have an OFT coming later this week. Do I need to have my dealer flash my (Aug 2013 build-date) 2014 to whatever the latest USDM ROM is before I install the OFT, or does the OFT not care? I believe the answer is, it doesn't care. Thanks!

OFT will marry up to whatever rom is in car. If you do go back to dealer flash back to stock then you can marry up to any new rom the dealer flashes.

Ok perfect that is what I thought. Thanks!

Full boost? It's much better to run lean, ya know.

It was a joke referencing @nelsmar's FA20club supercharger experience.

I want to use the 93 tune with it comes out, but I wonder about the quality of our (local) 93. What should I look for in the log (eg. afr?, knock correction?) to make sure our gas is compatibale with the 93 tune?

Check AFR at WOT above 5500rpm is no leaner than about 12 (assuming your N/A) most people would say tune for 12.5 or 12.7 but these motors tend to knock any leaner at higher rpm. arroud 11.8-12 is shiv's target for N/A on petrol maybe 12.2 on E85

If your IAM stays at 1 its a good start

Then check for knock both flkc and fbkc, you may have to put up with max of about -0.7 occasionally in 2000-3500 rpm area but outside that rpm range should be clear of knock.

I didn't know which bad tune you meant, but I expected it was from FA20Club. That's why I joked about running lean under boost. Poor Nelsmar, on his second engine. At least he didn't get FA20Club to rebuild his engine. Imagine what a nightmare that would be. It would probably take a year and be done pitifully wrong, or something. Naaaah! Nobody would make that mistake, would they?

Is it normal for AFRs to be hitting up to 20?
Been seeing it on the stage 1 as well as the stage 2 UEL tunes. I'm on 92 octane.

you should only see 20's under deceleration, not partial or wide open throttle
