I take it using a Nissan control system isn't an option?

Not without tedious reburning of ECU chips etc.

I will be temporarily using the Nissan Ignitor module. But the coils are apparently quite unreliable after 15-16 years of service. This could also be my problem. Buying the Nissan coils new is a $1000 exercise. I can go full CDI for just a little more, and start using less-expensive/better coils for the same purpose.

I had a bad experience with the CA 18 coil packs when I used to own an EXA. They went one after the other. $265 each + tax at the time.

My thoughts on the problem is the location of the coil packs, being fastened to the head, surely cant be a good thing. The amount of heat was rediculous.

hay ther r u shore itr ur spark letting u down.. i hav a sr20 with a microtek mt8 in it is just a stock sr20de standard everything and i waz playing with the coputer and i got it 2 brake up at like 2000rpm. it waz over fuleing and fowling the plugs...try remapping ur timeing and injection pules might hav 2 not run as rich..like i had 9ms at 2000rpmm and it just wouldn run..maybe try running a hotter plug..like thers no way u need 2 run that sort os injtion system wen i hav seen 200+kw running standard injtion systems...

Thanks for the help, But didn't you read the original post?

I'm not running the standard ignition. I'm running an unusual config by using the stock coils with a 2 channel Bosch ignitor and wasted spark method.

I am going back to using the "standard ignition", to see if this fixes it. (which it should for 98% of the problem).

Holy Crap Mrsr1200 from memory I run about 9ms injector pulses at about 12psi +ve pressure. No wonder it wouldn't run.

How good are autronics??? I'm contemplating going an autronic or a new microtech ls10. Can anyone help pursuade me?

Cheers

yes i did read ur original post.. but i still cant see y ur running it.. unless ur running avgas or sumthing like that.. and u 100% shore that its the spark leeting u down.. coz over fueling can casue it 2 barke down..hav u checked 4 cracks in the coils and in the baker light? hav u changed the plugs? im just trying 2 help coz sumtimes its the littlest thing that get u. ild start with the basics and then go from ther.. check 4 arking..

i wouldn no bout the autronic but hav heard good and bad things bout them.. but cant remember wat they wer... if u hav the $$ put a motek in it..

Hey guys. Time for an update.

I've had to learn about ignitions over the past week or two.

I now understand all about it.

I've found that my SMC dwell board is not working on all 4 ignition outputs. When you get a dwell board, you sacrifice ign 4 output on the ECU for tacho. You HAVE to run wasted spark using IGN 1,2 for 4 cyl, and 1,2,3 for 6 cyl.

Anyway, my dwellboard is faulty after all my efforts to get it working. IGN2 is overcharging the coils with 67deg dwell, and ignition 1 is doing bugger all with 4deg dwell. I found when I "enabled" special dwell control option in engine setup on the v1.92, that the dwell angles dropped to 45degrees and 3 degrees respectively.

Hopefully my ECU will get fixed and I'll be able to start running in my engine properly soon.

Cheers,
Chris

ps. I am going CDI, this dwell board crap is for idiots with a lot of time on their hands. So I'm also needing to remove the dwell board from my SMC.

pps. If you ever choose autronic, spend the extra money and go CDI from the beginning. Otherwise you'll be treated worse than a leper, and finding answers will drive you crazy.

Hey Chris, Glad to hear you are making progress. I have heard from others that tech support from the Autronic guys can be pretty ordinary at times, I hope that hasn't been the case with your situation.

I found that Autronic Lincoln in Newcastle is a top fella. He's sorting out the removal of the dwell board, and the supply of the R500 kit and 4 new high energy external coils.

Should be roasting the tyres in less than a month, maybe as quick as 2 weeks.

Let the Sun start shining for again! With the car running I might have time to find a religion.. or a life.

Lesson: Never get an SMC without CDI. The dwell board can really stink. I was unlucky enough to have a partially buggered dwell board. The dwell board needs to be removed by a specialist not a backyard job.

The SM4 has everything I wish the SMC had, software dwell support!! yippee! But with the external CDI unit, the SMC can get on with what it's good at.

Why have I been quiet lately?.. it's because my autronic ECU and it's ignition probs have been killing me for the past month or two or six.
