Denny's M62B44 swap (MS2 installed First start VIDEO inside)

SPARK tested and working!


Some good progress has been done recently... very close to doing the first start!

Got the Ignition sorted out.. with the QuadSpark installed the temperature on the little unit went up to 70degree celcius on Key On...so I knew something was not right.. 1 wrong setting in tunerstudio almost fried the Coil drivers. Thank god I build a good heatsink for it and didnt start the car... anyways I checked spark and all is good :) so next is Fuel / Fuel pump relay...going to use BMW relays so

special pic just for JEREMY :) 4 stickers x 5HP each = 20HP more...worth it to me lolll

Also while waiting for my Sparktester I built the shifter nicely centered..

QuadSpark installed with Heatsink best place I could find in the very busy enginebay

sorting out the BMW relay for Fuel Pump and power to Injectors..

here is my new tool.. nice little sparktester works really well

also while I waited for sparktester I worked on intake filter.. I got the biggest K&N I could find that could fit.. (I modified the OEM windshield washer bottle with a little heatgun action. (I will paint it flat black after its 100% done)

almost there for first official start stay tuned..

Oh i was going to guess race sticker. They add like 5hp per.

[Denny]

Well I got a huge scare... I tough I had fried my Quadspark or worst MS2.. one wrong spark setting...5 more seconds and I would of lost the spark battle..but I came threw :)

Very happy right now... so I move the next and FINAL! step before starting this M62b44 with pure all MS2 and new wiring...

whats NEXT!!??

Oh man ...I remember those MAF translator and the DSM world in general which I miss...Had a 1990 eagle talon TSI (Canada they were under chrysler brand called Eagle) didnt take much to bring the legendary 4G63 into the 11`s .. good times... then I fell in love with these little pesky bmw 30`s lolll

They were still Eagle in the States.

It's pretty important for forced induction engines, too, but moreso for the timing calculation, as FI engines tend to run much closer to the detonation threshold than NA engines.

A friend of mine has a '96 Talon with turbo upgrade and full supporting mods. It's cracked 11's on E85. Yes, I know that's not that fast by DSM standards, but it will serve to illustrated my point.

He has a DSMLink, GM MAF and a MAF translator. He wired everything up as per the instructions and tuned it. It ran really well. Then the weather changed and it didn't. We troubleshot it and found that the MAF translator has an internal resistor providing a dummy IAT signal that's always 80 degrees. I was about to go shoot somebody... One of the stupidest things I've ever seen related to engine management.

MS2 V3.57 with all the goodies even the infamous IAT sensor lolll (my experience tuning was limited to Forced induction cars all my life so news to me its needed so importantly for timing in N/A but I would install it anyways for extra protection too.)

I still don't understand it entirely. You've got the power coming from the igniters in the DME and the ground wire. The one I don't understand is the wire coming from the ignition switch. Is it just a constant 12v source for the coil to charge?

I'm actually using some VW coils with built in igniters for my Microsquirt unit, so I've been poking around the wiring diagrams to see what wiring I can reuse in my harness.

+12V current is sourced from the ignition switch, flows through the coils and sinks in the igniters. The igniter is just a high current transistor that can sink the coil's charge current.

The DME does not power the coils... it just *GROUNDS* them to complete the circuit.

"Smart" coils have the igniters built in as you mention. That means they need a +12V power, +5V control signal and ground capable of sinking the charge current.

more wiring...more testing.... making good progress

Calibrated the TPS to perfection.. I connected Starter and Cranked engine over to check for RPM (means the VR is reading correct :) Got 150 rpm and 3inches of Vaccum which is good but not great and I was wondering what the problem was ...well I found it :) The ICV was open so that creates a a vacuum leak hence why my vaccum test was just ok... I`m going to wires the ICV and tested it....closed it and recrank few times to re-test.

Also in the works going to built a heatsink for the quadspark...cause spark will be my next step...and finish with Fuel and then start the engine, tune for Idle....so on...

[Denny]

Awesome progress can't wait to see you get it running.

Very interested in the MS2 results. Keep it up!

Last night I plugged in my laptop to read the sensors done so far.. gave 12V to MS and everything looks good so far expect my TPS... (can only read from 20% to 70% so I will check this tonight and update..

You've probably got it figured out by now, but here's the wiring schematic for the E36 M42's which also use three wire coils. The M50 (which uses the same COP as the M62) diagram is the same, but the M42 diagram is a little easier to decipher.

I still have to test this out for spark when I do the wasted spark quadspark setup but so far from the ones that I talked too... 3 PINS (Greens=Constant 12V Browns=Constant Ground to heads (other PIN different colors) goes to MS.

Thanks Bro...almost there ... :)

More wiring done...etc....

• MS2 12V DONE(To battery direct for testing purpose for now) + 5A FUSE
• Grounds DONE + Engine
• MAP DONE
• INJ Bank 1 DONE + 10A FUSE
• INJ bank 2 DONE + 10A FUSE
• COP Bank 1 DONE + 30A FUSECOP Bank 2 DONE + 30A FUSE
• TPS DONE
• IAT DONE
• COOLANT DONE
• VR +/- DONE
• Starter DONE

Almost finished:

• IAC
• Alternator
• COP power
• INJ 1 and 2 Power
• Fuel Pump
• Wideband
• QuadSpark

I re-used the bmw M20 Coolant sensor just had to get the ohms-Temp good old fashioned way...beats having to remove and TAP rear coolant pipe..

every wire is Crimped and heat shrink (doing TPS in this picture)

IAT in the stock Air pipes..just did a rubber Gromet for it... factory look.

more to come... at this point (without Fuel and spark) I will start testing the sensor with MS2 plugged direct to battery to see if everything is ok so far.... then I will test SPARK and end with Fuel.

1K worth of Computer Engine management... and all you see is a 1$ socket used as a spacer

LOLLL..ok ok I will at least paint it:devil:

Coolant expansion tank...with some nice mounts :) who needs a 18 anyways

Are you fucking kidding me right now? That is some hard core Fab work right there! :loco:
