Has anybody else run into problems boosting above 1.6 - 1.7 bar with (3071R Turbo) the standard Pulsar ignition system.
If so what did you do to get round it ??

was talking to dooie about this the other day , dont believe he does have an issue uses the standard nissan system
you can always buy a hks amp for it anyways

get a decent dizzyless set up, theres plenty to choose from, its the future...lol
this one looks very good, is standalone so would work well with powerfc,e-manage etc.etc

Well, bearing in mind I've just had a mapping session with Ed, and using the standard coil with Denso IK27 plugs set at 7 thou, at around the 1.6 bar mark we got slight misfires in the higher rev/peak torque range, we think it's the standard (14 year old, designed for under 1 bar) Nissan ignition system spark not strong enough. Ed mentioned that Stu's car did the same thing after 1.6 bar.mattygti-r said:
I did have the MSD Blaster coil fitted last time Ed mapped my car but that did the same sort of thing only it was far worse and we had complete spark blow out in the same sort of place. At the time we thought it was due to the Nissan system not being strong enough to saturate the SS Blaster coil and thus the coil not producing a significantly stronger than standard spark and in order to work efficiently it needs one of the series 6 MSD Ignition boxes http://www.msdignition.com/ignition_4_6200.htm
Anyway despite the fact I have changed back to the standard coil, I was thinking as I already have a MSD Blaster coil I would get the matching above MSD Ignition controller box. Has anyone else here used it ?? as all the reviews and forums I've read have said they had good results.
Thoughts anyone ?
Steve
Yeah, I had the SS Blaster coil when I had the Power FC and the smaller turbo (GT28RS) and ran a max of 1.8 bar without a problem. I think that becuase I have upgraded to the 3071R and it runs that much more air that it blows out the weaker spark at higher boost.
In fact nearly all the people I know that swapped over to using just the Blaster coil on it's own have now swapped back due to misfire at high boost problems. It needs it's Ignition power pack thing as I mentioned above to work 100%.

Yeah I might try that, although at the moment I'm running about 1.55 bar and it's ok.ashills said:
Would like to see what happens when you do use the complete MSD kit though :-D .
What doe's Loui run ??

I have had lots of pulsars begin to get unreliable at 1.6 bar+ @ 11.9-12 afr. You can cure the missfire and run higher boost if you lean it out as the spark required to ignite this is less. (fuel is an insulator)..
Steve as I said if you get a driver that will correctly saturate the blaster coil then it will be a non issue, and you wont have to run silly close gaps that ultimately can cause a non fire due to other reasons....

I plan on getting the MSD 6A control box and the air temp sensor Omex use then make another appointment, so we can get rid of that MAF sensor and wind the boost up a little more :-DFusion Ed said:

Sounds fun 
May need to at some date arrange a Fusion battle of the best of all the 400bhp+ pulsars haha!!

It should work well, mine arrived this morning ;-)
