Jorge was using the Maf for low voltage part throttle and then it went to Map to add some IPW back in. You can use a flash in conjunction with the emanage and many people are doing this so that all the timing maps on the ecu match in all positions(see ecu stabilization thread). 8-9 psi is the max for the stock fuel system and also the maf. That is why the flashes are for that. Not the reasons you speak of.

Otherwise, its alot of reinventing the wheel finding and fitting larger MAF's, remaking intakes, sorting out the wiring, scaling the voltages, etc etc.

My post was saying yes you can. He won't be able to run as much timing down low but it can be correct up top. The ecu adjusts the timing even when the maf is maxed out. His flash can make the timing whatever he wants. The timing is somewhat related to the MAF but not to the extent you are implying. As long as you know where you are clamping/maxing out the maf voltage you can get your desired timing via reflash and then fine tune via emanage. I agree it's not ideal but remember he also ran the car with the stock radiator for awhile and living in florida it does get extremely hot and humid. I think it is more of a heat issue but that is my humble opinion.

ok here's the deal....I have the TS Greddy TT timing map on the ECU, but not the fuel tables. I had the greddy turbo map flashed onto my ecu in order to stablize the timing maps. When Sharif tuned the car he had a consult hooked up and determined that no further timing need to be pulled so he zeroed out the timing cells on the EU. The flash is not controlling the a/f the EU is handling that part.
Thanks for all the support guys! This feeling sucks! Especially since this is my second time experiencing it in the past 6 months. I got to drive my car a total of 5 months this year.

I picked up the car from the shop this morning and drove it home. They cleaned all the oil off the driver's side plugs and it runs fine now. It does not backfire or hesitate......pretty much leads me to believe it is the ringlands on the driver's side pistons.
Sounds pretty much like what happened to 350zDCalb and failsafe306.

gurgen - a proper MAP based system has a much broader range than that - using a 5 bar sensor for example, gives you a TON of zones to tune for on the positive side. While you are a bit limited on the vaccum side, it is more than enough on every standalone I've ever worked with to make idle and cruising speeds as well as light throttle/no boost situations as smooth as can be.
I think the primary reason for lots of the failures is the fact that you are not dialing in fixed timing figures, with set parameters, but rather a blend of the ecu and emanage under boost.
The key lies in the systems that have been used to date IMHO

If i were you, i def. keep the car, it's your project so keep it, def. get a beater and transform this to a summer only weekend warrior, thats my plan anyway, i am just waiting till the warrenty is over and i'll take the same path you have taken, good luck with your car and hope everything turns out for the best....

Adam-"not dialing in fixed timing figures"! IYO, are you saying that is the reason most boost applications are failing and that's why a standalone like the HKS FCON is needed in mid to high boost situations. I'm not trying to put you on the spot, just trying to justify my spending habits.(I've recently switched from eManage to HKS- installation going on now)
Thanks for sharing your vast knowledge!!

I had a leakdown test performed and cylinder #1 had 22% leakdown and #3 had 11%. We went no further. Most probably the driver's side piston ringlands gave. I don't know why.
The shipping company will pick the car up next Saturday 11/12. They were going to pick it up tomorrow, but I had already scheduled a complete Zaino detail for next Friday. It will show up in TX very shiny. Should be there before Thanksgiving.

Bro this really sux! I hate to see this chit! I just did a mod to my G. I bought a 700.00 95 Civic. Im going to beat on it until the whels fall off! Its always a great idea to have another car when modding like we do.
