Steve @slivel , Have you ever had issues with ‘floating timing’ with your HPV-1? I stumbled on a thead on the bird board where a notable race engine builder discovered some HPV-1s have an issue with timing retarding at 5000 RPM instead of holding or advancing. I think that is my issue, and the cause of my missing hp… Problem is still that my mech wants to cut a hatch in the firewall so he can put a timing light on the pulley mark to verify/compare with timing what the HPV-1 displays while on dyno. I still don't want to cut holes or relocate the coil boards, so were at a standstill… which is fine since I’m still dry on $$$. I have no data recorded that would show timing over an extended period of time - just the few times that the car has been on a dynamometer. My car has been consistent in power - at least as far as my butt dyno can determine - and lap times at the tracks that I used to frequent. I too, dread the thought of one or both of my Electromotive units failing. I haven't researched it but maybe there is an aftermarket crank-fired ignition that could use or be adapted to use the toothed wheel and pickup from the Electromotive. This would be my choice for an ElectroMotiv replacement: https://www.clewett.com/index.php?main_page...&cPath=1_71 |

Yes, this is what I’m considering, although the website says “sold out”.
My mech wants me to go COP, but I don't think I need to spend the extra $$$. |

Actually, for others that may be interested, I had a brain fart and forgot about the 1-2-3 distributor. Fully programmable and probably less expensive than an ignition-only Microsquirt setup.

Fully programmable and probably less expensive than an ignition-only Microsquirt setup. https://123ignition.com/product/tuneplus-4-r-v-porsche/ I looked into the 1-2-3 and on the advice of our very reputable race shop (Rothsport) passed on it. They've had nothing but trouble with them. If I were to retain a distributor system (rather than crank fired) I'd look hard at the Mallory. I'm not sure about a 6 cyl version. For my application it would be basically a T1 unit, which will work in a T4 engine, or so I'm told... I should add that I did leave the trigger wheel on the engine along with the pickup bracket - should I ever find a suitable replacement for the ElectroMotive. Give Clewett a call. They're old school - phone is best. Really nice and knowledgeable people. Talk them through what you're doing and they'll hook you up. |

I've been running the Megajolt system from Autosport Labs for many years with success. Its a wasted spark system similar to Mega squirt. I've only run it in a single plug arrangement but others claim to use use it in twin plug arrangements.
