tuning help?

[drift-it]

hi guys,

so i've had success tuning my trans in my l67 vy calais and decided to have ago a getting rid of up to 9 degrees k/r at 5600rpm during 1-2 gear change. so i set the main advance vs rpm (extension) to 0 in the range of 5200-5600 at 850-900mgc.

this worked! i no longer get knock at gearchange. however i started adding advance back in that area and im upto 8-9degrees advance but in the log the advance still goes to 0 in that area? do i need to go higher or am i missing something?

ill add a log of before when i got knock, a log after i zeroed the advance and a log of added advance. also ill add the bin with the 8degrees advance.

cheers,
zac

are you changing both the low and high octane maps?

[drift-it]

just the main advance. so im guessing high.

[drift-it]

ahhhh low octane is on 0 advance in that area. but im running bp ultimate?

[The1]

They call it that but it's not really what's being intended. It's a main table and knock retard table. if you get knock it goes and use's the low table for a period till knocking and retard no longer exist by a certain amount then it will go back to the high table.

so what im trying to do is stay out of the lowoctane advance? or am i able to up the timing from 0 in the lowoctane?

[drift-it]

well i jsut did another log with the low octane advance between 3-5degrees and it still went to 0 at 5,600! starts going down hill from 8degrees at 5,200. and still no k/r.

the only thing i can notice is it corresponds with the trans slip. trans starts slipping, advance starts going down. trans stops slipping advance is going up...

is this at 100% tps or is it fluctuating?

[drift-it]

100% tps, wot as it gets to 5200 timing starts dropping from 8degrees and by 5600 its at 0.

this is the log i just took tonight.
