Double post.

[quote=Good & Tight;4392699]Those afr's are way to rich, sub 10's are really bad. I wouldn't keep running it like that, you can lift the head with that much unburnt fuel.

With a proper re-tune you will be over 500to the wheels.

What size is your exhaust..?

Thanks for the heads up.

I have a mandrel bent 3in all the way back to a borla race muffer.


I was going to request TRM to take 10% fuel out across the board and another 5% between 4-5500rpm. What do you think?

Here are some pics of the eventful weekend. Dyno day and Chicago E30 Meet.






SO Minty!



Right hand drive 320i Touring!



320i motor.





s52 swap on the red one and an m54 swap on the M-tech 2 vert. Both very clean swaps.















Back in MKE. No problems all weekend except for my tune which needs tweaking.

Dyno run

The zf320 has the 1:1 ratio in 5th gear so this was my car at 165mph!! It was deafening.

While they were programing the Dyno Jet the only option that the computer had was a 2.93 diff setting. I'm running a 2.79. Would this change my numbers?

TRM will send you a tune revision with the correct adjustments. Call Mike and get it sorted out. Your car looks perfect with those wheels..!!

[DrLeadFoot]

Apparently the speed sensor is required to operate the ECU. I need to get that fixed ASAP along with a cam sensor.



How does the speed sensor tweak the AFR?

Vehicle speed is used in a few maps in MS41, like rev limit and heavy throttle vanos activation... Probably more.

What did you pull those codes with?

Thanks for the info!!

My guy has a bluetooth snap-on code reader. Pretty slick.

Really great what youve with the car. Its pretty much what i'm going for in terms of looks.

BTW My e30 swap does the same thing at WOT shows almost the same AFR. I tried connecting the speed sensor but i'm not getting any change. I'm most likely doing something wrong. Interested in seeing what you do to get this resolved.

My speed sensor is totally disconnected. Hopefully that will solve the problem once it is hooked up.

Have you scanned your ECU?

I haven't scanned my ECU but i'm using the non vanos 402 ecu, In hindsight should have chosen a vanos engine. So i don't think it has the same capabilities in the way of scanning, well thats what i have read.

I've run a wire from the back of my dash (greenplug) to the corresponding wire at the x20/c101 adapter, but it hasn't changed anything. I've yet to run a voltmeter across it to check if it is getting voltage (10v, from what i've been told).

I hope you find a solution to the problem :)

How do you like the 2.79 ratio diff with the ZF? I ask because I'm running a 3.73 and have the option to go 2.93 or 2.79 with the ZF. No boost on my car, but I'm still interested in what you think.

In 5th going 65 it holds at 2400 rpm which is cool with me. If you do more auto-x I probably would go with the 2.93 running N/A.


Might pull the trigger on some wheels.

These for the front with a 10/15mm spacer running 245s

For the rear running 265s

I'm debating on the platinum (link for the front) or the hyper silver (link for the rears). What do you guys think?

[MatRacer]

I would go with hyper silver...I like your car a lot! Very inspiring for me!

I'm just about to try a 3.15 with a ZF320... THe 3.73 was horrible on the long run...
