Help with my Dyno results (charts attached)
Right now, all I have is a MBC and cams (272's). The power is obviously dropping alot, and I want to get the right tune. I have tried to read my ECU with ECUFlash and is says "Unkown ROM Image". I'm extremely new to all of this, and really need some advise as to what to do. I will not be doing any of the work, and I have about 1k to spend on mods and labor. Is it possible my ECU cannot be flashed? How bad do my charts look? Any input would be appreciated...thanks.

If u still have the stock exhaust that isnt too bad. But why would u have cams and no exhaust unless u bought the car used like that. U are also very very rich on the top end. I would say if u have a flash that it is set up for alot more mods and other hardware thats not on the car. AFR should be mids 11s not 10.1 thats almost if not as rich as stock.

I dont think ur low end and midrange are too lean unless alot of knock is present. Im that rich on spool up as u r. Usually a completley stock car is still leaner then that on the on sight of boost.

I've been trying to get it tuned, but the "Unknown ROM image" message we get is stopping us. I think there could be a chance of frying my ECU if we "attempt" the tune. The tuning options available to me are ECUFlash, ECUtek, or an Xede. I can't afford the Xede route. If I got tuned properly, I assume my power increase alot on top, right? What would be my best tuning option, and how much power could I gain? Again, I'm really new to this, but need as much help as possible.

Overall, I don't think it looks that bad considering you have the stock exhaust. If you add an exhaust and get it tuned, you will pick up a few ponies. As for the ECU being locked, you might want to check with MalibuJack. I seem to recall reading that someone had a method for getting ECUs to accept a flash even when they were locked. I'm not 100% sure it was him, but he'll probably know about it.

If the profile looks identical to stock, I'm assuming it does not have a tune now. Is there anyway I could find out for sure? If ECUFlash can't read my ECU correctly, would DynoFlash or another flash / tune be able to unlock it for me? I'm thinking catback or tbe, and tune for my 1k to spend. I just want it all done asap!

YOu need a TBE, fuel pump, bov, and tune. You could get all that for $1200 if it were a mail-in flash. We need to figure out why it doesn't recognize the ROM, though. Have you asked (or searched) in the EcuFlash forum. I'd bet that someone else has encountered this and knows the solution.
