SBEC to SMEC Conversion ?

:bump:

Actually, the 60-way SBEC connector should physically plug right in the SMEC, but DO NOT DO THIS until you swap the appropriate wries around. Damage to the SMEC will result otherwise. Many of the pin positions are not common and a few of them need to be taken out and spliced into the 14-way SMEC power connector. Compare:

(sorry, don't have the SBEC T1 one up yet, but you get the idea). Observe the power feeds in particular.

That is what I thought but wanted to confirm. I might be able to get you the information about the SBEC pin out, if you don't already have it. My question is what injectors get grouped on driver #1, and #2 since I will be going from sequencial firing to batch firing? Thanks.

1+2 and 3+4.

I can get you some pinouts if needed.
Russ, this goes for you as well, I have access to all chryco fsm's, if you need anything for your site I will be happy to provide it.
Send pm if interested.

I believe you are correct, based on the diagrams I have seen. The SBEC probably has non-volatile memory to store such things.

xrattiracer: thanks for the offer. I have 85-88 and 91, but I will let you know if I need anything.
