Haltech tune

[9c1vs]

Hi, i'm new to this forum and I am researching as I am leaning towards getting rid of the haltech sport gm that is currently running my car and putting the delco back in.

My engine is a 355 stroker with small cam. The haltech runs the show fairly well and I have become quite good with haltech's ecu manager as it is quite easy to use.

I wish to go back to the delco as a lot of the features of the haltech i dont use such as all the boost stuff. I also miss out on a couple of features including lean cruise, correct fuel consumption data and knock sensor, which are all things i want back.

My question is if i were to install an nvram chip can i use my current ve numbers and be pretty close? And can i enable the knock sensor using an nvram?

Cheers

yes you can use a nvram.

If it is VS Series 2 or earlier you will need a V8 knockboard on a memcal to fit onto the nvram. If it newer MAF style then it work with the delco ecu.

Ok cool yeah its a series 2. I have a memcal with knockboard. Do i take the emprom out and put the nvram in its place on the memcal?

If you have one of VL400's nvram boards all instructions in PDF, but yeah nvram on top & knock board hangs off back with correct jumpers selected!
