AC menu for the V6?

[coolflames]

I am running my GTP motor with a custom made intercooler that uses a 2" thick heater core under the blower and a aluminum tank that encases the AC evaporator. The tank is filled with antifreeze and a 5GPM Flojet circulates the coolant between the cold tank and the intercooler core.Basicaly I am using my vehicle's AC system to keep my engine cool. :huh2:The question- can you add the AC menu for the V6 on the next update, that would really help me get the most of my setup. Thanks.

will add to the list, although i'm not sure if it operates the same the V8 as yet. I can;t promise it will make the next release either at this stage, but it will happen.

If you send me your OS ID (via email) i can make sure yours is first to be done and you can help me with some testing if you like.

I also have another question(maybe you will have to move this one). I hear people talk about the 3 bar GM MAP sensors and I know that my motor i equipped with a 2 bar MAP. My MP112 blower makes about 16PSI boost with the INTENSE 1X cam and ported heads/open exhaust/intercooler. I am also planning on running more boost(up to 20PSI) and the 2 bar MAP only reads up to 14.5PSI. If I do get a 3bar MAP, how can I use its readings? Is the VCM suite capable of working with a 3 bar MAP or should I just stick with modifying the PE and don't bother with the 3 bar MAP?

[Chris@HPTuners]

personally, i would be looking seriously at a speed density tune with an extended VE table and perhaps a boost referenced fuel table. This would all be custom code, but doable.

You probably could get a bigger MAF and still run with it, but i'm not a big fan, although Ken would probably disagree

The issue you have is that the tables are quite small in the v6 code and even with stock MAF and around 12 PSI boost, you are off most of the tables such as spark (which maxes at 6400rpm & 0.92 g/cyl.

My intercooler is now ready and my email is screwed up- I can read messages, but cannot compose and send any. Let me know what kind of testing I can do for you and if you can send me an update.

[Chris@HPTuners]

please post your Operating System ID in this thread and i'll send you an update to test.

about the 3 bar map sensor, you could plug it in and use it but,, you WILL loose a lot of resolution on the map. You would not have to extend the table either. It does not matter if you have a 2 bar or 3 bar map sensor, they both read 0 to 5 volts, all that would be necessary is to apply a know pressure to the map sensor and read what the pcm thinks it is, then make adjustments to your calibration based on these readings.

Really though it would be better to extend the table!

Not quite that simple... Firstly all the MAP based tables and the scanner MAP reporting will be out by whatever your scaling factor is. Also, you need to go thru and factor every single MAP calibration in the PCM, again non-trivial. Internally the PCM limits to 210kpa (without scaling).

Stick with the 2 bar and just wing it with the PE table fuel when the airflow maxes out.

IMO, to truly use the 3bar you need to ditch the MAF and run SD with a 3bar VE table and appopriate code mods to actually use MAP up to 3bar without the need to scale your whole calibration with a fudge factor.
