timing is set to about 10-12 - runs like dog **** if I retard or add more it runs like ****
850 red turbo injectors
npr intercooler
3 inch exhaust





so yeah whats next

A failing AMM. I have run into this issue several times with 7-9 series turbos. That is why the problem comes and goes. A 780 I bought would run perfect one minute and couldn't get out of its own way the next. The boost gage would be pegged and the car was producing 25 hp at best. Good luck finding a known good 007 AMM to put on there to see if this is the problem. K-jets has a couple of good 007s if you want to try one. If you plan to keep this car, you should buy one anyway while you still can. They are getting to be VERY hard to find in good working order.

You may have a bad connection. That's what I hate about 2.2, no diagnostics. The fact it comes and goes like it does indicates it is something electrical, not mechanical. Waste gates don't fix themselves.

that was a consistent problem only on Sbbabs ecu. Im just waiting to see what he says

its my understanding that the ezk will do first 1-2 pulls as the base and then adjust accordingly with each on/off cycle and that's exactly what was happening to me

So you're running 315cc injectors and some china turbo at what boost? You could be out of injector at 5.5k when the turbo is making peak boost.

I suspect multiple things coming to play here.

Spark timing is too hot for a B230+16v+t. Really Simon to chime in here on that side of things.
System functions normally on a stock EZK tells me the spark tune is causing the issue.
Pinging up top, your running pretty small injectors for that power level. Also you're beyond the scaling level of the stock MAF. Watching even a 230FT with a K and T3/T4 it was pinging the top load row by 10-12psi and carrying that timing level on as boost built. A stock tune at 25* was not happy at increased boost levels. The larger MAF allows you more scalability to tune for the higher boost and stay on the map.
Injector sizing on 2.2 doesn't play near as nice as 2.4 does.

I didn't think anything related to 2.2 learned anything, unless sbabbs chips are different.

Jack, just to clarify...you were using a sbabbs modified EZK box that emulated a stock 16vT EZK (B204GT?).
Ref: http://ipdown.net/jetronic.info/tiki...p?galleryId=14

Fuel computer is stock B230FT.

THe chip has the stock 16v turbo ignition map on it from the 2.4 16v turbo 208 EZK. It is a conservative ignition curve supposedly I have been told by others more in the tuning know all(MrJayBeeze).

THat being said, there could be something wrong with it say in the soldering of the socket onto the board a bad connection. I did test it in a car and it ran before I sent it, but that was before I swapped in the 16v turbo chip. I guess send it back and I can check the chip bin and I could burn a new chip easy to adjust the timing map to what you want. Say take the 8v map that works good but less timing up top. THere is that development thread where I posted the tunerpro xdf and the files so you can tune it yourself and email me the bin and I can program up the chip. I am not a professional email tuner, that is not my gig. I just program up stuff to do get with the program. Other people have done all the tunes I have mostly. I have cut and pasted maps in other bins. I don't have a 2.2 car to test anything. I'm all in 2.4 but that's just me..

I'd be looking at running out of fuel given the injector size. 315's are pushing it at 15psi on an 8v, let alone a 16v.

Also, anybody know the stock SCR on a B204FT vs a B230F+16v? Different bore size along with a change in compression may be adding to the mix.

Your injector size is way too small. The 16v head flows more air than an 8v head and you've added a turbo to that. IIRC the stock 740 turbo injectors are 290cc and you've gone with 315cc injectors on a head that flows more and a much bigger than stock turbo.

You're wondering what the issue is.....

I dyno'd 209hp/236tq to the wheels with 8v IPD cam/lh2.2 with the Ford brown top injectors I sent him.
