Help needed! converting 202 to delco

[Charlescrown]

I'd just try with the standard VN program. It can't be too far off the mark.

i did try the straight 6 tune on there but it seems to be corrupted in some way? im no expert but maybe i dont have something set up right. Ill attach a photo of the spark advance table.

You are using $5D xdf, which is incorrect.
You need to look here viewtopic.php?f=27&t=356

thanks, have figured it out now. I should be alright now, unless i have any issues with installing the NVRAM. Thanks for your help v6bucket

yep definitely start with the tune v6bucket linked, it was run on a stock blue 202 with VK manifold and injectors so it should be a pretty good starting point.

my recommended approach, disconnect the injectors and then jumper the diagnostic link plug to get it in diag mode, then wind it over and adjust the dizzy till its on 10 degrees advanced (and hopefully your balancer mark hasnt moved) then you should be in a pretty good position to fire it up.

Thanks for that. That was actually a question I was planning on asking!
Cheers

Hello again, two things this time. The first being, how do i "jumper" the diagnostic plug. Im not quite up to date with the terms yet.

Also, im not quite sure how to wire up the coil. I am using the standered one that came on the vk efi engine so its different to the one that you had in your photos. Just wondering exactly what should be connected to the coil and where the destination of the wires go. Ill attach a diagram to show what i mean

I am not sure what the wiring colours on the VN loom but the + PNK pink wire is switched ignition and the brown BRN C is the coil trigger. Make sure you ground the HEI module. I would go to the wreckers and grab a VN coil with the connectors to make it easy.

[v6bucket]

The HEI coil is fine, connect the Pink wire to the + side of your coil & Brown to the - side.

There's a pic of the plug half way down the page, use a paper clip to bridge "A" & "B".

Thats a good result then.
