If you upload a new tune to the slot with the "*" on it its no longer the tune in ecu. the "*" just flags the last slot written to ecu OFT does not actually check or compare :-)

So its probably a good thing that I reflashed it right?

If you own an Automatic running E85 in the US check this out.

Any way to log injector duty cycle on OFT? direct and port

if it will log injector pulse width then you could use this info from moto mike

DI 6ms and PI 15ms max for 80% duty cycle

DI duty is very dependant on a number of factors so isn't likely to be a logable parameter. Its not like normal injector duty at all. If you could set up to use multiple parameters then it may be possible to do one of at least calculate it. You would need RPM, DI Timing, spark timing and injection pulsewidth to give you a value.

Is there a way to not lose my throttle response every time i reflash? Or do I always have to wait for it to relearn ?

So i can log my injector pulse width at a given area? thats only thing i have not been able to find in oft logs or tunes. ill be going turbo in a while and i want to know were i stand on maxing out my injectors so as not to cause a lean condition. those 2 links are very helpfull

My oft has log parameters
inj time DF
inj time PF
suspect these are injection time port and direct fueling, if you dont have them make sure your oft is up to date and you using the latest ofm software

i use tactrix for logging injectors as it samples at 20 times a sec as oposed to 5 , but oft should be sufficient

on E85 which is actually 85% my di gets to 5.8ms at just below 7200 (afr about 12.4) at full di then at 7200 where the 20% port kicks in and reduces it back to about 4ms over7200 rpm , this is NA though

as @Kodename47 said di window is not jist related to rpm , the romraider calcs are for port only, heaps of other factors come into play, i just stick to moto mikes recomended di max injection times which a couple of other tuners confirmed

excellent thanks alot..i just want to have all my info before slapping on this turbo.. ive learned about rushing projects on my last two bolt on turbo cars lol

Any tips on deleting multiple log files at the same time? I'm starting to log again and I had 5 files that I had to delete individually. Normally I wouldn't mind but I can't delete the file until it fully loads, which takes about 20-30 seconds each..

mine lets me delete while it loading

@steve99 what would be your opinion on which AVCS maps should be used for this P&L header?


I think it'd be somewhere in between a short runner design such as stock/HKS and a long tube one such as Nameless, but with the added restriction of a cat?

Or should I just run OTS stg 1 AVCS maps?

@P&L Motorsports is on this forum, they might be able to supply that.
