VT V8 304 MAF NVRAM -> VS V8 MAP NVRAM + M122 SC Conversion
Posted: Thu Jul 13, 2017 2:04 pm
Hi all,
I have a 1998 VT 304 Calais which a little while ago I bought NVRAM hardware for and have been logging and slightly tweaking various parameters with TunerPro RT to learn about the Software and tuning parameters.
I have been using The1's Enhanced Bin, XDF & ADX files for the VT V8 5L Auto which have been great.
I have been observing how Spark map adjustments and AFR target tables affect the motor's performance, and tweaking the auto's shift parameters/pressures has been educational and productive.
All has been going well, but I really want to move into mapping VE tables as I have an Eaton M122 Blower to go on this motor and I believe the current factory TB and MAF arent going to cut it once the blower is on.
The vehicle is nowoff the road and I have time to really play with this motor and trans. I will be building a roller Dyno (no hydraulics as yet, just for safe "Off-the-road" roller tuning)
After I have the Motor and Trans really banging, I may engine swap them into a much more interesting body... but we'll see.
I am milling the intake to house the M122 and will also find suitable Seimens Deka Injectors (maybe 60 or 80lb) to suit the 7-10psi I will be running the Eaton at.
I have looked at Conversion questions (MAF->MAP) and it seems people advise going to a VS/VR V8 304 PCM (ECU) and loom (or rather adapter cable I will build from VT PCM->VS PCM) to gain VE table mapping. or maybe the far more complicated LS1 PCM conversion?
So my Questions and requests are:
1) What model VS PCM should I be getting? BZMT, CKUN, BWFU, etc...?
2) What are the Correct pins for said VS PCM to hookup Wideband O2?
3) Please can someone provide the correct Pinout for VT 304 AUTO CALAIS (MAF & Climate control) & VS 304 AUTO (MAP) so I can build a proper adaptor/Loom with Wideband support? - (I have scoured google but can only find a ton of variants other than the ones I want)
4) Can I use my current NVRAM chip with an updated Bin to suit the new VS PCM, or are they different?
5) What Bin, XDF & ADX files should I use for 2Bar VS V8 304 Auto with wideband logging?
6) Do you want me to do a full Photo/Video writeup as I complete the build?
7) Please advise any things you think I may have missed.
Thank you in advance for help and advice.
