does anyne here have a holden v8 tune for 2 bar on ose12p.

Hi guys,

I rang 2 dyno shops and after telling them the combo, one said he doesn't know how to use the ose12p and declined my offer to sit in the car with him to show him how to use my laptop.

The other shop was too scared to even touch it.

I have just got my car back on the road after a transmission meltdown back in February and It looks like i'm on my own for getting the timing in the right spot.

I'm looking for more power to try an get into the 7's down the 1/8 mile. although the car feels strong I still think it has more in it with the spark in the right spots.

as is, the 0-100 kpa map is filled entirely with 28 degrees and the 100-200kpa map is filled with 28 degrees but reducing 1 degree per column for each 10kpa boost. seeing 11.5-11.8 afr on boost.

I have cheapo head gaskets with stock head blts and have not blown a gasket yet with upwards of 15psi. (2 bar map sensor but goes over the 200kpa row in the logs)

Another thing is the fuel pressure. Running standard fuel pressure regulator but I'm wondering if I'm losing power due to the smaller pressure difference between the injector and the manifold on boost.

does any one have any experience with a boosted engine switching between a standard regulator to a boost referenced one? would i get any more power from this mod?
I have 80lb injectors so I am still getting good afr's.

I've ust looked at a 2 bar v6 tune on this site but the timing in the 100-200 map in that tune is a LOT less than what i have in mine. wonder if i'm losing power from too much timing?

does someone have a good v8 2 bar tune i could look at of preferably a 383 stroker 2 bar tune?

here's my bin file for ose12p, 2 bar petrol adx.

if the AFR's are that rich and your injectors arn't maxed then increasing fuel pressure is not going to do anything.

why are you running 28degrees across the whole map ? the whole idea of the points in the map is to give it what it needs all the time.

i don't know alot about boost, but i know some n/a motors will not handle that much timing!!

I'm running 28 because i don't know what the motor wants and 28 just seemed like a nice number....

without a dyno how are you supposed to know what timing to give it?

0-100kpa should be able to be left pretty much totally stock apart from any low rpm timing changes for a cam

I ust opened a stock tune bin and clicked select all on 0-100kpa map and "copy" as soon as try to copy the map is closes the program..?

That stock timing map looks a bit inconsistent. there is 35 siting right next to 27...

I thought it was supposed to go gradually and smooth? (maybe not so smooth as mine...lol)

I have the idle timing set by getting best vacuum, do you blokes get a mate to go for a drive and go for best vacuum to set the 0-100 map or do you's just normally leave it stock?

I'd love to weld a set of truck axles under the ground and use that for a dyno... maybe hook it up to a big agricultural grain drying fan..
