Title: Gunni 318i/M42
Post by: Gunni on March 29, 2006, 06:42:21 AM

Hi guys,

nice to have a M42 only forum

I´m running a M42 powered 318i ´88,
I got the engine from a Red 318is that was hit in the back,

I swapped engine, trans, driveshaft and rear end in completely,

Car was hand painted before, but serves as a daily driver now, and
will always, I plan on painting it myself in a form of dark green (E30 original)

I´m runnnig a M20 flywheel, M20B20 clutch and pressure plate,
I had to mod the starter and use 1.5mm shims to put the starter a little more in front of the trans to not get the gear to stick, other then that it was all direct bolt on,
flywheel was lightened to 5.5kg or so, I used the pic Jordan made up in CAD.

I have raced 2 E30 325i´s at stoplights and was even all first 3gears.
I do have a SMT unit lying around, also a M30 afm , maybe putting the things together, who knows, maybe a MAP,

I do have a Zeitronix Wideband I have yet to install to check the AFR,
And this car doesn´t have a O2 bung in the exhaust from factory.

I´m putting it on some "16´s soon, not wide or anything, it´s just my "15 BBS one wheel got a flat tire and I dont´have any more "15 tires ;)

Anyway I guess thats enough from me,
Most of you know me from R3V, E30tech, BEN, or whatever.

I also need my username changed to Gunni :)

Hi Gunni, welcome! You got any pics? Where are you located??

Indeed I am that dude from Iceland,
but why THAT dude??

what are you getting at,

I´ll post pics later on,
It´s got a Mtech I front now but poorly done by a PO so I´ll change it to facelift again

yeah man... sorry, I should have been more specific... yer 'gstuning' on E30 tech? either way, welcome!!

pls. check out our first 'ASK SO-AND-SO (http://m42club.com/forums/showthread.php?t=207)' thread... if you have any M42 questions for the man, they are totally welcome.

enjoy the board!

Thanks, I like individual based forums as it´s keeps more technical and less nonsense,.

I really don´t have any q´s for him, as I plan on running this as a daily
altought, I´d love to do this to it,

but until I have a secondary car, wich will be a 3.5 E30, I will keep hands of any standalone stuff :)

That's awesome, someone swapping in a m42, that's a rarity, finally someone smart

SMT6 install tonight,
ign control, fuel control,
Wideband as soon as I can,
Also MAP swap as soon as possible as well ;)

As promised I´m the best, ;)

I installed the SMT unit along with the wb controller, no sensor in the exhaust yet, but I did connect the MAP sensor and TPS to the SMT unit and WB unit,
Also I connected the MAP sensor into the SMT as a MAP signal and a analog signal, thus beeing able to fiddle with it ,
I connected the AFM signal in as temprature signal but only to monitor the voltage on the graph, I then mod the MAP signal until the AFM signal and MAP signal are identical, then I remove the AFM signal from the ECU and tap in the modded MAP sensor signal into the ECU

I will have to make up a housing for the temp sensor and a resistance for the old AFM circuit, but more on that later,

I noticed I had about 14-15psi vacuum and not so good idle,
I advanced the ignition 10degs on a couple of spots and now
no more hesitation of idle and idle is alot better and vacuum is about 17psi

I´m about 85% way there to a ignition controlled and fuel by MAP sensor controller M42,,

I didn´t solder the wires as I wanted to make sure it all worked ,
Also I need to reroute them to make it look better,

I was VERY pleases with the ignition controll as it´s always been a hassle on other cars I have put SMT units on,

I think it might take me about a week of real hard monitoring to get the MAP output configured for replacement of the AFM signal,

I´m very happy :)

95% way there,

today I and Stefán went on a drive ,, we where able to map out the MAP output to almost simulate the AFM signal identically.

idle is done,
most of lower part throttle, WOT almost, I will have to do some datalogging to finish this up,

then it´s time to simulate the presence of the AFM for the ECU and cut the MAP output signal into the ECU I will have to install the air temp sensor into the intake path also, this is probably the most problem

, I will have installed a Wideband sensor when I do that, to be able to fine tune and make things work better,

NOTE : I was able to monitor the AFM signal, and at about 4-4,5k the signal goes wobbly, probably the harmonics of the intake messing with the flow,

Here is a text file with the Wideband AFR measurements I just did,
http://www.gstuning.net/files/files/m42stuff/m42brakes_on.txt

This is WOT readings.

So you can see that there is some room to manipulate to go a little
richer.

Post by: Gunni on April 27, 2006, 04:41:54 AM

Today might be the day I move over to the MAP signal,
I will not be able to remove the AFM just yet as I haven´t gotten myself a replacement Air temp sensor and don´t want to ruin this fine AFM,

I also am planning on hitting the 1/4 mile tonigh, so news tomorrow

gunni do you have news and spec of your SMT setup? be nice to see!

Post by: Gunni on September 14, 2006, 10:05:44 AM

Hey, not really, I´ve been staying away from this forum to keep me away from the M42 :) , as I need to keep my mind on these M30 swaps I´ve been doing

The engine now sits in my garage and the checkerd interior I have
also the rear end, and front end,

I had the car tossed as it was in the way and dying on me,
I have since picked up another car, a 316i 4door weinrot,
I will build this into the winter daily when I finish a 333i I´m starting to build

I´m really tempted at finishing the map swap , It was all ready , just had to unplug the maf and install a IAT sensor and wire it back,

Also the car has a tow hook :)
I love those tow hooks, they make the car so versatile.

pics later,

Well I´m on my way back in the sattle of a M42,
on my way are headbolts and a top gasket set,
so when that is done the engine is ready for it´s new house

a 4door veinrot e30 with a tow hook..

I´ll post pics as things take shape,

I´m going to use the wideband and proablably SMT6 again,
I really am going to run without a afm to try and see if there are gains to be had with fuel and ignition control + no afm.

ohh a 3,91 IX viscous LSD ,,
and yea pics as things develop
