I drove the car for about 45 mins to 1 hour and in the end did some pulls in 3rd gear.



I think there is a misconception (or generalisation) about EU fuel. We have (Germany and Northern EU) fuel that is at least on par or surpasses US fuel. Actually there is equally a common misconception here, that all US fuel is crap.

Anyway I run 100 octane Shell V-power (we got 102 octane Aral as well). And I have 0 flkc / 0 fbkc and IAM 1 with Wayne's 1.08.2.

However I will leave it as it is until I see how it's working at the track.

As for how it feels, I can't feel a difference in power as expected. But the pedal tuning feels very nice, more aggressive generally and when accelerating from within the torque dip it feels more linear. Best way to describe it is there is a better correlation between what you demand and what you get (I make no illusions that I am actually getting significantly more power in the torque dip).


Thanks!

How does the MAF look in the log? 12-13 during the pull should be okay?

I will have a closer look at the guide:

Looks fine. Openflash Stg1 runs intentionally lean compared to Stg2. If you want it more in the power band you only need to copy the AU.Rich scale over the top of Stg1. After you add more timing with it rich it may or may not make more power than running leaner.

Not use that file and find/make a genuine D00D ROM.

If you search for ZA1J in the hex editor, what are the other results?

It only appears at the 8000 line thats it.

No, it will appear more than once.

Did you search for just ZA1J?

There should be 3 instances of CAL ID in a ROM, and all will need to match.

Yeah only za1j and then at the 8000 line it gave me za1jd00d

I checked again and i found it again at the 10000 line but didnt find it again

As kodename47 said their are three calid in rom unless something is rearly wrong

just search for ZA1J dont search for ZA1JDOOD, what we are trying to establish is if all three are same their should be ones at 8000,10000 and a bit over 11000

got a bit of an explaination here

http://www.ft86club.com/forums/showthread.php?t=61820



the noise arround 4000 rpm with EL header tunes is normal and due to valve timing\overlap to remove torque dip if you rearly hate it you can reduce exhaust cam by 10 degrees but you will get more torque dip back in that area

Thanks, I will have a look at the link.
No I like the noise it makes. It has a very aggressive sound to it. Just curious what caused it and that I wasn't imagining things.


Another question that is Tactrix related, but not tuning related. For track usage, I could see the logging feature being very useful. Particularly if it would be possible to log either brake pressure or brake pedal travel (probably easier), e.g. via a potentiometer connected to pin 12 via the 2.5mm jack. Would it be possible to define the output of pin 12 in the logcfg.txt?

Hmmm im not sure im following you with the brake pressure, thats probably monitored by the vehicle sability module rarther than the engine ecu i think unless your adding your own sensor.

the 2.5 mm jack on tactrix is set up to monitor inovate wideband im not sure what voltages it expects might be worth emailing the tactrix guys, ive never used it.

Yes, I meant brake pressure via own sensor. Hence, I would think it's probably easier to add a potentiometer to the pedal. Probably not as accurate as monitoring pressure, but probably enough to pick up brake technique mistakes or spot bad habits.

Seems like it would be possible, another project for the winter.


P.s.
I read the link you gave about KCA and now I think I understand what you meant with "be careful with adding timing". Because the ECU can't pull as much timing with Waynes map as the stock one can (lower values in KC Advance Max A), in case one would add much too much?


Again, thank you were much for your help.

[lizbrayan]

So I made a zip folder that has my stock rom from the ecu and the oft stage 2 uel 93 tune that "has" my calid. @steve99 and if some of you other guys can also help me out thatd be great thanks!
