VT V8 304 MAF NVRAM -> VS V8 MAP NVRAM + M122 SC Conversion

[The1]

The1, am I able to do variable based math in the 'calculation' section of the item ADX? as in calculation with variables other than the item itself? or just basic math for that item variable?

You can do what you like in the adx calc

You setup a Value item for example in the ADX as normal, but packet offset doesn't matter for value just leave it at 0

for Calc just remove the X which is the reference the packet in the general tab, but create your own calc, you can also link to other values in the adx, like mine below in enhanced mod which just compairs target afr with wideband input.

I think i remember there was an ADX around that would use a map sensor on an input pin and maf sensor and generate data in history tables, like VE tables, even though the car is running a MAF sensor. If i find it ill post it.

Yeh Map has it over MAF when the intake air path is to long as obviously the MAF is to far away compaired to a MAP sensor in the plenum.

Sweet! such good info.

Good to hear my crazy ideas are potential real things that can be achieved (phase-change IC) I presure the unit would get heat soaked pretty quick without some serious upgrades to the factory External AC fans


I've been wiring the PCM & ECU today:

that ADX if you can find it will be great... I'd have to use the MAP in open air as BARO initially on the VT PAM to calc VE and populate a table... would be an awesome/easy way to get a VE table setup really fast to copy over for when I first run the VS ECU, if I can't get Antus' suggested bin to work.


I'll just have to setup:
D8 as WB, and D10 as the MAF input on the VS ECU, and
A5 as WB, and B10 as the MAP input on the VT PCM

here it is, it was for VS V6 S/C, but you could set it up into any enhanced adx.

Legend! I'll have a play

[JA2Z]

Where is the safest place for me to pull a MAP 5V+ reference voltage from the VT PCM?

[charlay86]

B7 probably. I think it is connected internally to A7 anyway

[JA2Z]

Awesome! was my first thought, glad I'm on the right track. thanks.

Looms virtually done.

At this stage I have gone with a custom wiring switch bank, as it was cheaper than relays, and will look cool.

Maybe later I will change the DPDT switches for relays. For now, at least it looks goods.

The Switches fully Break/Make - Make/Break the whole injector set.. so there is no way I can bridge the VT injector GNDs and cause 4x fueling to occur - either the fueling will work perfectly, or not at all. (no confusing half/way options)

Mmmm, soldered and loomed.

Loom Done! Complete with Wideband Loom

That's fantastic, pretty quick to.
Good work!

Watching with interest.
