M6B Tragic

Thanks for the compliments Leon and ditto to your build also. It's magnificent.
I also want to thank you and Andrew for your responses on my Distributor issues. It has got me thinking, and one of the critical targets of this build was to have a strong reliable car that at the end of the track day I can come home and give it a clean and a service and park it up ready for the next outing. I didn't want something fragile and temperamental that I'm constantly fiddling with.
So, after reading your feedback and having a long chat with my One Man Technical Advisory Committee ( Clayton ) I have decide to look hard for somewhere to cram 8 coil packs and start pulling it apart. It's the way I should have done it to start with, but "Oh No", I had to have that authentic Magneto look.
I will still have the look by stripping the dizzy bare and have it sitting there doing nothing.
Plus a very nicely tuned engine.
You win Clayton, I should have done it to start with. Hindsight, Hey? Now, to find some space.
I look forward to seeing how you jump this hurdle. Not something I had to worry about with Old School injection and to be honest, Thank goodness because I have NO skill when it comes to electrical wizardry.

Cheers Leon
Hi Udo,

Thanks for the update - sounds good. Out of interest, what approach are you planning to take to get an accurate engine position signal for coil near plug ignition.

Cheers, Andrew


Hi Andrew
I’ll jump in for Udo, we used the EFI connection kit that is also marketed under the Chevy Performance banner.
It uses the LS crank and cam sensors in a custom front cover to suit the 572.
The injection is already setup for sequential fire and will now use batch fire on the coils (only 4 outputs from the Haltech 950)
Have a look at post # 135-137 for pictures of it fitted.


I'm back. Sorry Andrew, but no residual interest. ( thanks anyway )
Okay Leon, here is how we over came this next hurdle. I purchased a set of ICE LS 4300 coil packs and they pack a wallop! Managed to mount them out of site down low on the chassis. Then we pulled things apart and Clayton de-pinned and re wired the computer end while I wired up the coil pack end. You can see by the pictures.
You're not going to believe this, but after checking the timing I hit the ignition button and it burst into life and sat there idling at around 1,000 RPM.
Not a splutter or a pop, just a crisp clear idle. Both Clayton and myself just stood there open mouthed in amazement.
Even when giving the throttle a blip, it was without hesitation.
I took a video of it, but do you think I can download it on here?

Wahouuuuu ; excellent news UDO !!
congratulations to you and the "wireman" Clayton" ;) for such a good work in finding the solution ....
Do you have now a long list of small jobs to achieve ???
are you planning soon to do a first track checkdown ?
Can wait to watch you driving this beauty on circuit tarmac !!!:p
Just watched the video some mn ago ; excellent Idle , now need some new one with some more revs !!!!! LOL
Superb !!!! Absolument excellent
merci Clayton !!
Shame you where not close to me to help ; when year ago we tried to fire up the Le Mans Lancia Stratos ( we had simlar issues until we did something similar to you and suddenly roarrrrrr she started for ever !!!!
Hope to read soon that udo and you are on the way to go to track !!!!!!!!!!! LOL
Great job Udo, what a moment to savour.. 572 cu of awesomeness.. at full song it will be quite something..
One thing I can’t recall you mentioning, are you going to have any engine interupt on the liftless upshift gear change.
…regards. Andrew..(the other 1:))
Wow!! what can you say that hasn't already been said, just an amazing quality build in every aspect. That Electonic injection has alot to do with the great starting I imagine. Mine does start and Idle straight up like that now but not with out a lot of setting up on the dyno to get the fuel right and then there is still the guy with the squeeze bottle of fuel manicly squirting down the injection while the other guy works the starter, but isn't that part of the magic of these car's ???. I'm pretty much living in WA now but will go back to NZ a few times a year to make sure my wife hasn't changed the locks or there isn't a completely new family living in my house and she is in the Bahamas. So send me your phone number and we'll have a catch up.

Cheers Leon.
Thanks a lot all of you for your nice comments, it's appreciated.
Regarding your liftless upshift question Andy, I hadn't even thought about it. My Prosport Mulsanne had it via a micro switch on the gear stick, but I never gave this any consideration, guess I should have. Maybe I'll just do it the old fashioned way and use the clutch pedal.
Hey Leon, are you up in the Pilbra? My number is 0418840279.
