What chip(s) will work with a 2.7 SETA bottom and an "i" head?

[phenryiv1]

Are there any chips that are shown to work better than others for a SuperEta-based 327i build? I have a 1988 M20B27 bottom end and the 885 head from a 325i.

I see a lot of chips that will raise the rev limit and open up the M20B25, btu I don't come up with much for the Super eta with the i head.

I have 19 lb./hr injectors, as well. I have the stock "i" 14 lb. ones available, but I'd rather go up to the 19s.

TIA

Yeah, Im interested in what you come up with, I'm running stock 173ecu with stock maps, but got a split second MAF conversion that really straightened things up on my b28. I still want the car tuned professionally though...

I am running a similar setup, with M30 AFM and injectors. Would really like to know what my options are for chips.

Here I get all excited in thinking that I have 2 suggestions...

Well, gentlemen, it appears that we wait for an expert to chime in...

Did you go straight to the M30 AFM, or did you run the B25 one for a while? My local JY has an M30 with an AFM that I could get for cheap. Does it use the stock B25 intake boot? Is it a direct bolt-on at the I'm side, or does it need an adapter?

Also, what size are your injectors, 17.5 or 19?

(It is my thread, so technically it isn't thread-jacking!)

there isn't going to be an off the shelf chip for any 2.7i

but it doesn't matter that much, if you have a working O2, and a 2.5 chip for the injectors you're using, it will run just fine.

I went straight to it, because I bought the car with all of this done to it, but I think it is a direct bolt-on or it might need an adapter as I know the M30 AFM is 3 inches on the filter side and I believe the M20 is around 2.5, not sure what it is on the manifold side honestly so I can't tell you. M30 injectors I want to say are 19lb.
