93-Octane MarkD chip in testing, feedback

[rwh11385]

Yeah, I just had short time and then came back to my appt. It was at least out of the blue, but not at the 1/4.

Speak of the devil, I am running off to class!!!! Or fuck it, bringing my laptop with me. :twisted:

And I gotta swap the JC back in and compare, and hopefully another pull on film with that.....to compare.

haha, running out the door.

Hey Robert, your clip seemed slow to me, so I made one of my own before I went to class. 2nd gear, slightly uphill.

Take THAT M30 parts boy. :twisted:

[rwh11385]

*cough* stock wheels. :?:

Dude, let me reduce duty cycles and shit.....the idle still hunts, because of the 19#ers. I went for like a couple miles. I'll post a updated video when I get home and the 50 mile drive gets everything right, and engine properly warmed.

Bring it Twin. ;) Race to the 1/4 mile or Dyno?

[Mystikal]

Dyno sounds game, it could finally quiet the skeptics on the forums too. Hard to find the time with school and work though.

Oh, and I am running 195/60/14's. They don't make THAT much of a difference though. :P

Pardon some of my ignorance on this subject.....but they say the only dumb question is....

Anyway - I could be way off base here, but I understood the reason to get the JimC chip vs. the Dinan one is because the JimC one changes the map for all throttle positions, where the Dinan only affects wide open throttle. Does the MarkD work like the JimC or Dinan one (of course, if my premise is off, let me know).

What does the chip change? Red line? Spark Advance? Anything else?

Thanks!

[Stu]

they both seemed slow to me. :?


:P

edit: gearing is similar, both cars are at ~52mph at 6000 rpm

[rwh11385]

Stu, Shut yo face. :P

Jay and he's cheating 195/60-14s......there's a 2.9% gearing difference around-abouts. ;)
When I'm at 60mph, and he's almost at 100kmph, he's closer to redline.......at least to my perception.


jblack, hopefully Mark can field that question, but I felt it was like JC throughout the rev range and throttle positions......just that when the cam kicks in more or less, he's upped the spark advance and taken advantage of the 93 octane,

Thanks!

In my chips, I have changed the following:

- PT and WOT fuel and timing maps
- rev limiter in manual transmission cars
- top speed limiter in most manual transmission cars.

My tuning methods are probably closer to JC than Dinan, who I beleive often changes only the WOT maps.

[jblack]

Good answers! Thanks!

[rwh11385]

Hey Mark, what is the revlimit on my chip? Just wondering. Seems Jay went to 7000 on his run.....

[Mystikal]

6900 I believe, the swing of the tach makes it seem a little higher. The 91-octane chip has the same limit.

[Matt86es]

Eta chip?

Any chance of a 93 octane chip for an eta? I have a 91 octance JC, but it seems a shame to waste the last 2 octane points when using 93.

I've never thought of a 93 octane ETA chip. I could tune up my 91 octane version and try to find a car up here to test in. I don't have any idea how many people are interested in this and don't want to develop it if it didn't really sell. I've developed other chips that work extremely well but don't sell.

Hey, I cruised with a friend (who has a video camera) and got more video.
A 0-100 run, turning onto the road again, then gunning it to ~90.....then 0-60 from a stoplight.
(I *think* 0-60 is about 7seconds now.....)

Anyway, here it is, enjoy. Had to downsize it a bit, to 7XX k bits/sec, as it was 16MB, now is half that so I could host it.

It's so dark its hard to see...what was your 0-60 time before the chip?
