60-2 trigger wheel setup in VEMS

[chaloux]

Hey all. So I've already put in an email to Marc but I think that this is good information to have on ze forum, and perhaps the community can answer

What settings need to be changed for a front pulley mounted 60-2 trigger wheel? I'm assuming almost all changes will be in Primary Trigger settings?

I'm also using the CPS, which was not in use before with IIc (wasted spark).

Quoted from Marc on S2forum (I lubsdainternet):

Vemstune makes the process pretty easy. just go under base setup->primary trigger settings.

at the bottom of the page where it has a drop-down that says "defaults", select 5cyl_60-2. it will set a bunch of things on that page. burn the settings.

Now go to your ignition outputs visual page and make sure all of that stuff makes sense.

Next up is the really important part, which is zero-setting your ignition timing. where your flat teeth are can vary from setup to setup, so to dial it in go to tools->ignition lock and set it to some small value, I usually use 1 degree (you'll need a dial advance light set at 1 to make it line up). alternately you can edit your timing map so it cranks over at 0 degrees. entering "0" into the ignition lock disables the feature. Grumble.

so with timing locked at zero, go to the base setup->primary trigger settings visual page. flash your #1 wire against a known TDC cyl #1 reference mark (flywheel, balancer, whatever). if its off, adjust your "TDC After the trigger" setting until it does line up. If you have to move your value under 60, or you run out of adjustment on the top end of the field, you'll need to shuffle your ignition output order so that it can be within that range.


dont forget, you need a cam sync for this to work. no wasted spark 5 cylinder possible on vems due to a firmware limitation (only 8 ignition phase entries. you need 10 minimum to do waste spark on a 5 cyl. I've asked for it, probably a coming soon feature).

before any of this matters, you need triggers first. if you dont get any spark check your triggerlog to make sure the wheel is being read properly by the ecu.

Is ANYONE using a 60-2 setup? I'm wondering if the fidanza flywheel has a reference pin on it.

[Marc]

lots of people running 60-2. my instructions you found are still valid, follow those.

Yep, that is how I set up my VEMS on 60-2. If you were able to look at the config off the IIc offline, you could just mimic the setup he had on that and import that figure into the VEMS.... Of course you can't, and so that is hypothetical talking

I rotated the trigger wheel on the pulley though. But yeah looking forward to firing it up today!
