your specific strategy
I know that is the code on your ECU, but what does it exactly means? I know from my awful Siemens Mercedes ECU that if you do a binary read out of different cars, the maps are located at different positions or offsets in the bin file. Is this comparable?

Basically the same effect between strategies. Tables and PCM data will be slightly different across each strategy

I am so jealous of making live tune changes lol. The hardest part of tuning with SCT PRP is having to reflash after each revision.

Annoying and unique "feature" of the manual transmission is that you cannot release the gas pedal and press the clutch simultaneously as all other cars I drove before. If you do this the engine revs up by it own, so release first, then press clutch. No idea why.

Interesting feature. Does it only do that when the car is moving?

I haven't heard of this as a default "feature"....sounds a lot like RPM flair between shifts which could be an issue with the Dashpot preposition being set too high in the tune. Does it happen everywhere or just while moving?

Yes, if you shift from 1->2->3...... It is on the factory tune and all other tuner tunes I had. The S550 does the same.

I mean there will always be some sort of delay in throttle input if you are literally just taking your foot off the throttle pedal and clutch in at the same time that would cause RPM flair...because the clutch has to travel to disengage while the throttle has to travel to close. If the RPM flair is really egregious, it can be adjusted in the tune via dashpot tuning.

Curious to see if anyone has mapped this out. For the Ford Racing Hot Rod cams, I am looking at updating the injector timing to account for the earlier IVO + longer duration. Has anyone successfully mapped out the exact Fuel Injector timing that is optimal for the Hot Rod Cams? I can't seem to find the full cam specs + IVO to be able to input the Fuel Injector timing away from stock (345 crankshaft degrees). I have seen some post 331, some as early as 311 degrees, others mention 350 degrees.
