ok if you load that one with $5D xdf file you should have the following:

F1 SAMAIN: Main Spark Advance vs MAP and RPM = main spark advance table.
KFCORPML: Run A/F Param - Hi RPM fuel cutoff - LOW limit = fuel cutoff lower rpm .....
KFCORPMH: Run A/F Param - Hi RPM fuel cutoff - HI limit = fuel cutoff upper rpm .....

pretty much leave the two numbers for the fuel cutoff the same distance appart ... ie. if you change the upper limit be 500rpm change the lower up the same amount.

fuel curve is altered by adjusting the following table:

F29H: Volumetric Efficiency (VE) as a function of MAP and RPM

I havnt looked at the bin yet but noticed it is 32K .Arent all $5D bins 16K .

Thanks Holden202. So I adjust things the correct way,In the VE table ,eg.if I adjust from 78.13 to 80.08(5600/70 intersection) on the table does this increase fuel(Richen) or decrease(lean)?

[delcowizzid]

yip higher ve is more fuel

[v6bucket]

Ok. Thanks. I'll see if I can confuse myself.

Yep. VE 'volumetric efficiency' refers to how efficiently the engine can fill the cylinder with air. Depending on vaccume and rpm, the cylinder might get say, 80% full of air (it pretty much never gets completely filled before the valves close), so this table tracks how much air has made it in, so that the correct fuel can be delivered. More % efficiency = more air in the cylinder = more fuel delivered to get the right mixture.

Well, I tested a couple of chips in the last few days.The 2 bar chip has done the same thing as the previous one, engine starts then stops.I used the same chip as before so maybe it wasn't erased properly?. The n/a chip runs ok but seems a bit to lean,I used the VE table from the Crow cams 284 bin,but its not right for methanol.Back to the drawing board.

I'll be away for a couple of weeks so wont able to reply. Merry Christmas

[Holden202T]

if your running a 2 bar bin and it doesn't run but a 1 bar bin does are you changing map sensors to suit the chip ?

[v6bucket]

Yes the 2 bar sensor was used with the 2 bar bin.
