I dealt with the same **** for almost 5 months already.

I don't have quite as much power as you, but the car drives like stock (except for the noise level from the exhaust, fuel pump, and HKS injectors). PM Hal - he is a magician with this unit.
+1...if you don't have WBs, with a car like yours...why don't you just get them? I'm running dual WBs (which the haltech CAN control each bank independently)...there wasn't HUGE variation...but up to like 5% difference between banks...enough to think you've got it tuned for 11.5 but be breaking into the 12's!!!
anyways, with the WBs in closed loop...my car is running like a champ. Call up greg at Injected, they've got some wicked good deals on the Innovate WBs...they'll really take care of you!

Also with my factory NB it would throw a CEL. Haltech modded the board for me and all is well.

I have to let off the gas for seconds at a time to almost "reset" the throttle or something-that is what it feels like at least. I also have WOT hiccups that occur when gunning it starting from 5000rpm's or so. The most frustrating is the cruising A/F's that gradually get leaner and leaner eventually turning into sputtering and making me let off the gas then get back on it. I cant even set my cruise ciontrol the car hiccups like crazy.
This is the main reason why I havent really been driving my car at all this summer, it just hasnt been enjoyable and spending more $$$ at this time to make things right *again* doesnt seem like an option anymore. I did drive another Haltech on an almost identical setup that didnt experience so many issues. Maybe one day I'll have a car that runs the way it should.

For me I'm wondering if getting the ECU re flashed would make a difference. I'm guessing the ECU is trying to learn around the new tune and there for jacking things up? I don't know if thats true but something has changed and its not the utec tune.
I'm hoping a re flash, Hal and a Haltech will fix all my problems tune wise for good.
Good luck it sounds like there is some really good support on here for the Haltech, I had considered the Fcon Vpro, beings there is a shop close by that is able to install and tune it for me. But with the Fcon being locked, I'd be screwed if this local shop went **** up. Then I'd always have to trailor my car to a HKS Pro dealer. And that's probably along ways away.
I'm hoping to get it to Hal soon, and then in the future I can always have someone locally tweak it if needed.

The ProEFI is the most impressive aftermarket ecu I have seen to date. Incredible stock like drivability, tons of options, O.E. quality. What more can you ask for. Can't wait til I can afford a turbo kit...

werds thats pretty nice...
Raj, what else would you use the osiris for though(along with haltech let say)....i mean if getting rid of cels is the only goal for shelling 500+$ then i personally have no real use for reflash in this case other than a little annoyance of a harmless cel
about the other guy, he need to be more patient, and ovbiously listen to his tuner.

The reflash for fixing CELs is really the most valuable part if it works... I already had Cipher, which is invaluable as a dx tool, so it wasn't much more for Osiris. The UpRev folks did create a map with AFR targets that mimick my Haltech tune. It didn't help entirely with the closed loop CELs though. If I stay under 4k rpms, I can run several hundred miles without a CEL (this is how I passed inspection last year, with test pipes no less). Besides the cam timing differences will always throw a CEL in the mid to top end of the rpm range. Now I'm trying to just eliminate all the CELs I have logged over the last several months of driving.

2. A CEL sometimes provides important clues that something is wrong. It is nice to have it actually mean something when it lights up.

I am also very curious about eliminating CEL codes via flashing the ECU. I know two of the big shops do it, they just won't say exactly what codes they eliminate.

The rev limiter in a RevUp is controlled by drive-by-wire and none of the Engine Management Systems (that I know of) can change it.

Oh i was curious too about eliminating cel codes, but its not worth 500 bucks to do so....
I am not really a fan of just jacking up idle rpms for unnecesarly wild cams...thats why i liek cams like the one raj has and my personal preference then BC stg2
anyways getting the thread back on topic......
did the OP go for the haltech yet?, if not...what ever his choice is think its worth the jump to a standalone if he an affort it.

This only apply to Revup?

I was relating to that particular posters situation being similar to mine.
Since you seem to know my situation so well I have sent you a PM.

If this works for me, I will post all the details (if UpRev has no objection)!
