Question about reprogramming ECM

[AllenF]

Hi Folks,

I am in the midst of modifying a 1956 chevy pickup to morph onto a 2001 Tahoe chassis. I need to add the electric fans and update the ECM to take advantage of the 2 speed and temp features, but what other mods are possible or make sense? I don't need any high performance mods (I don't think???)

Any suggestions as to what to do or where to send it?

Thanks!

Allen

you can send it to my house when your done with it .
since its going to be pretty custom it wouldn't hurt to have blackbear performance poke around with the tune a bit. maybe if you hit them up they can also offer some other suggestions.

No suggestions, but it sounds like a really cool project.

Wonder if my floor pan looks that good. Doubt it!

Interesting project, Allen, keep posting up pics, maybe start a build thread.

Cool project..Blackbear would be good for tuning the PCM. I would go with an 03+ PCM if possible as this will give you better fan control. Hydroboost would be nice and EZ to retro fit into your setup as well to ditch the vacuum booster..
