[Gmecm] Re: How to wire Timing Bypass on 4-Cyl 151 Iron Duke?

[Aphelion79]

Well... for unforeseen events leading up to the lack of spark in my 
Mazda truck and the unavailability of any form of standard parts being 
Japanese and all (lol whatever the reason is) I decided to try to fix my 
Heep ASAP... so... I spliced the tan/black wire.... set the timing to 
zero... at zero it runs like crap.   Plugged it back in... and the 
timing advanced... however what should the timing advance to on a '88 
Chevy S10 Pickup with the 2.5L?  For it still runs like crap and idles 
funny (maybe idle is just set too low? dunno its late to think about it 
anymore)  Any other ideas as to what I would check (sensor wise) as to 
why it'd be idling funny...  so yeah
