From Mike at AMM:
Steve,
I did not see a heck of alot of timing advancements, but we never checked the race-gas maps. Next time we'll hook up and check out the high octane map to see what they have if you want.

Who knows? Maybe the ECU was cutting back on the timing when in map B.

This is true.
That is probably why they say to use higher octane. To help reduce denotation so the ECU will not retard the timing, which will cause you to lose power.
I think your dyno proves this.

Not to be on the negative side but if it were mostly due to MAP signal alterations then the VAFC and E-Manage could do the same if enough were taken. I would love to see the maps though as I suspect timing to be a critical part of it.

scalbert -
Maybe you could give UniChip a call a discuss with them the tuning methid that they used to produce the results. Maybe they will tell you if they did it with timing, fuel, or a combination of the 2.

(102 mi. 2+ hrs drive) my preference is to have a baseline dyno done with my existing mods then a second set of pulls done with the chip installed then further tuning done if the tuner believes more power is achieveable.this would allow for all dyno runs being comparable with "same day" atomospheric conditions. the only drawback to this scenario is the timing between baseline and chip install and tuning (doesnt allow for ecu self adjustment) - comments anyone?
I work less than 5 miles from GRD. I called them and set up an appointment for a before and after Unichip dyno for Saturday afternoon on July 10th. I have been wanting to do a dyno on my '02 TLS for some time so now would be a good time.
They said they could also custom tune the Unichip if needed. Cost for the first hour is $150 and $100 for the second hour if needed. Will let you guys know the results.

Wow, you guys were definetly right about Jack.
Got off the phone with him a little while ago after a 20 minute conversation. I explained to him what I had been observing after using the chip for a week, my concerns, some of the weird things it was doing, and asked him my options. We discussed the possibility of a custom tune, although there are NO unichip shops in the area, infact the closest one is Altered Atmosphere in Maryland where steve got his done!
Pretty much what was decided is that I'll sit tight til the revised chip he sent out to one member can be tested, and if this chip works he will reflash my chip for free. This should take care of all lean conditions and any other concerns. He said of course I will get the most out of a custom tune but unless I am looking for max dyno numbers (which I'm not) then it will be enough of a tuning with the reflash just for having some fun on the street.

Just got an e-mail from Todd. They want my car for some dyno workouts on thursday with a friday pickup. I'm in. Still runnin' the stock intake though. Have to hooky a couple of 40 mile rides now. I should of checked the option box for the official Acura fold up trunk mounted mini-bike. Sieze ya.

Hey Ant. I've been waiting for an icebox to come up for sale on the black market. Fat chance. My car has the CT headers and suspension and rolls on 17 inch GT1's and 225 es100's.

just got back from the dyno
car is running way to lean, af ratio is 14.5 w/ chip, 12.5 w/o
car is actually detonating through vtec.
as far as gains though there really isnt anything, like 1 hp and about 5 ft pounds for only like 500 rpms
i put down 250whp w/ the unichip and 248 w/o it
i will post the graphs later i have to scan them....

engine is running alot smoother now that the chip isnt in...
as smart as the people at uni-chip are wouldnt they know that a universal chip wont work, if i would of kept it in any longer my engine could of possible blown up
i'm gonna talk to jack on monday and if things dont work out imma tune it with the greddy e-man

No it would not have "blown up" Your ECU will detect the lean condition and retard timing accordingly to keep things safe, this is why you aren't getting gains. The ECU is cutting timing.

What kind of dyno was it BTW and are those #'s SAE or STD?

I'm assuming you used a dynojet and although they have become the "standard" for dyno testing because of their "reliability" you have to look at these numbers for what they are. Dyno testing only give you an estimate of the power being produced. Now with Darrin's mods, 248 whp seems nuts! That would mean he is pushing over 300 crank horsepower. I'm not saying it is impossible, but the real thing to look at is the difference is stock vs UniChip dynos. It is very possible that Darrin could have his car tested at my dyno and run 25 whp less, or I could have my car tested on his dyno and run 25 whp more!
The factor that doesn't change (at least shouldn't change that greatly) from dyno to dyno is the A/F ratio. It seems as if Darrin's car is right around where mine was with the UniChip. You'll need to get that back around 13.0-13.5 to get it running better.

It would be cheaper to get a custom tune on the UniChip man.

New email from Jack:
Steve,
Thanks for the reply and the additional information. The changes AA made are
what I would have expected from the A/F trace we saw from the first dyno...
what they really did was have the Unichip pull less fuel. Why your car is so
much leaner even before the Unichip was added is a bit of a puzzle.
I don't think timing is a big power factor... if there's not a big difference
between the A-map and the B-map, timing isn't what the car wants. Comparing
Matt's dyno runs isn't ready valid... different car on a different dyno; the
only useful comparison is looking at the before and after charges between the
two cars... his vs. his compared to yours vs. yours. Even then, they're
different cars.
Please let me know if I can answer any additional questions and let me know how
the next drags go.
Cheers,
Jack

When I spoke with Jack on Friday he said to just hang tight til they can get the modified map tested; and if it works he'll offer anyone a reflash who is running lean. But I forget when he said it would be ready and tested, I think the beginning of this week .. has he mentioned this to anyone else?
