S52 finally!

2" to the roundel, 1.5 to the lip.

1.5= 38.1 mm, thinking I don't want to be all the way out so 30mm?

Looks great out in the daylight!

Thinking I need spacers, how can I tell what size?

Drop a plumb line off the fender lip (can tape it on), and then measure from that into the wheel/tire.

It runs! Feels great!

[parkerbink]

99% there! Should be driving today!

I just put in the trans & differential fluids, all that's left is running the hoses from the PS pump/cooler to the reservoir & adding fluid. Taking a break & then I'm dropping it off the jackstands & going for a ride.

I'd think like anything eventually they fail. Not a lot of humidity in Phoenix so I doubt it's that.

lol

[Panici]

Glad you got it sorted out.
I wonder if the MAFs can go bad with time? Maybe humidity in the air?

[parkerbink]

27 year old MAF is the issue, verified by removing it & it idles. I had a cheap Amazon on hand & it runs fine. Ordered a new OEM.

Whoops I completely misread that.

I think a bunch of people make BBTBs, I don't know if it's worth it for an FI car. Probably should have a tune adjustment for TPS enrichment if you do.

[parkerbink]

Tuner has not responded. But I'd love to know if I should get the 9% biggerr TB.

Stolen from bf.c:

There are THREE Bosch 3.5HFMs that work in the E36 Cars... the 800, the 803, and the 806.

The software Dinan (and all the other chip tuners use) will drive the 800 (BMW 540/740) and 806 (BMW Euro M3) HFMs. The 803 is one Porsche uses and most Turbo guys run that as it has a different voltage/metering characteristic.

If it's just the MAF itself, it's likely going to be one of those two.

If the tuner says you need a MAF, I guess you need the MAF. Otherwise I'd be looking for vacuum leaks.


Edit: derp you said throttle body, not MAF.

[parkerbink]

I was offered a DInan high-flow throttle body. Does anyone have any input on them?

[parkerbink]

Nope, OEM.

[moatilliatta]

Did you do big maf?

[parkerbink]

Starts right up but does not idle. I emailed the tuner asking if he sees anything in the file needing attention.
