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

I've been playing with real-time VE calcs in The1's Enhanced adx:
MAF is G/S
RPM is R/min
Baro is Kpa
0.287 is Gas constant for Kpa
IAT is Deg C
0.04156 is Displacement(L) / (sec -> min) / (crank rotation per powerstroke) = 4.987L / 60 / 2

Hopefully Baro is actually read by the VT PCM? Or I'll have to setup the VT PCM like 11p to sample baro from new MAP sensor at key on

Now to find time to install the looms back into the car and test both ECU/PCMs

Then to order VR/VS NVRAM, then tweaks

Welding on the Wideband Bung

Nice welding. Just wondering given that the bung looks pretty long, does the sensor protrude far enough past to expose to the gas stream?

[JA2Z]

Thanks,

I did wonder the same, but the MXT-L Manual specifically states that the 1" bung provided will help protect the sensor from damage without affecting readings.


As far as I could tell it does exactly that the readings looked spot on to me at times (14.7 under most idle conditions, etc... )

Looms are back in the car...

Car started.. (eventually, after finding the fuel pump earth wire wasn't mounted on the chassis) and the Wideband shows up AFR as expected.

MAP is plumbed.

VR/VS NVRAM is ordered.

Now to take some logs and wait for NVRAM to test on the VR/VS ECU.

First run done yesterday after installing the loom.

Battery was a bit flat, but enough for a first start.:

Im loving this

Keep the videos coming

[JA2Z]

Battery still flat, but Wideband installed and MAP hooked up:

Reminds me of the days when race was on for first Vt L67 into 11's.

Dicks Electronics were fitting earlier map ecu to run engine & I think still had original computer to run everything else.

Back then had vt ss 5.0 auto with boltons as daily & featherweight lc gtr 195i getrag 3.9's

Looking forward to blower going on!!!
