M20 AFM to M30 AFM with 19lb injector questions

[CorvallisBMW]

Did you only install the m30 AFM.... cause if so your running lean

No, I also put on rebuilt 17.5lb injectors, 8mm plug wires and a K&N cone filter w/ heatshield.

Is there something I'm missing?

yeah, the M30 AFM was designed for a different engine with a different ECU and a different tune with a different calibration. :roll:

mine did the same thing, weird huh, sometimes it runs good sometimes it runs like poop.

this may be worth a try, disconnect both battery wires, and touch them together. This completely clears any memory in the ECU. Connect the M30 AFM and then reconnect the battery.

This didnt happen to me but I'm just trying to help.

OK so I finally installed the '027' M30 AFM today. Idles like shit every time I start it, then smooths out after 30 seconds or so. Plugged the M20 AFM back in, runs fine. What gives? I let it idle for about 30 minutes after installing the M30 AFM, and then drove it to work and back to give it a good workout. Is there something I'm missing?

i used design three ... which are the thin ones and they work fine

[Kingb]

ok cool. Those are the ones that I am going to buy on ebay. They are $55 with free shipping rebuilt

[E30_fiend]

are these design 2's?

these are the ones that i have

mine have black where yours have silver but they could have been paint stripped. Those are most definitely design 2s

On ebay there are a set of design 3's and there are another set of 19# but doesn't specify what design but they look older so I am guessing those are 2's.
I will look for the 2's

design 2's are the ones that are skinny then fat then skinny

Design 3's are about the same skinny size all the way down

So is anyone using the design 3's or is everyone running the design 2's??
At the junkyard I found a 96 mustang V6. The numbers on the injectors are 9F953. I haven't found anything on the internet as to what these are.

Design 2's are easier to come by and they also work better for the swap.

I am planning providing a 63mm throttle body, 027 AFM, rebuilt 19lb injectors (design 2, heard design 3's are problematic with this swap),

Ok bro, here's the deal, M30 19lb injectors or high impedance injectors. ETA injectors which I believe are 18.5lb injectors, are low impedance injectolrs. All they would do would be mess with your ECU's reading of the fuel injection and most likely not even let the car idle.

Thats why they are saying dont worry about it.

clarity at last!
