Using Holden202's $12P Methanol Tune In A V6

[Jayme]

yes it does lol. go open up the VE table and type in 120 and save it and open it again... 99 VE is FF which is the max.

I've think I've had a bit of a win. I've got it revving ok, but it's now running pig rich. do I adjust the idle afr in the VE table or somewhere else. This is the latest log.

you probably don't need to adjust the AFR tables, generally you want to look at the 20-100kpa VE Table and make the changes there.

After 20 litres of methanol, I think I've got bin to test in the car.

Here's a brief log.

[Holden202T]

did you need to change much to get it working ?

[v6bucket]

I had to change a few things around to get it to idle & rev. "Idle A/F Ratio vs Coolant Temp"& "Initial Run A/F Ratio Offset vs Coolant Temp" needed changing as it was idling at 4.3 afr which is way to rich & filling the sump with methanol. I don't know how many times that an eeprom can be erased & burnt, but the one that I'm using has been played with at least 18 times. It would be handy if I was using a real time tuning set up that VL400 sells(hopefully in the near future).

how much did you have to change the values to get it right ?

[v6bucket]

The Idle AFR was changed from 5.2 to 6.4. Wasn't huge changes but very time consuming.

[Holden202T]

well actually that is roughly a 25% change and yes that is pretty major, if your needing to change that much then you really should be leaving the idle AFR tables alone and adjusting the VE table!

I don't know how many times that an eeprom can be erased & burnt, but the one that I'm using has been played with at least 18 times.

Generally more than 10,000 times so I think you will be fine
