here is mine
around 50 km done since the flash, 3rd gear pull

http://datazap.me/u/walla-walla/stag...1?log=0&data=1

is it me or it seems like my pull is a bit more lean than the one from silver ignition?

waiting from comments of someone who understand all those parameters!

Its actually a bit richer higher the AFR number = leaner, lower the number = richer.

As @Malt said ditch the VVT intake and VVT exhaust cam parameters and replace them with FLKC (fine learning knock control) and FBKC (Knock correction). it looks like you have a bit of knock but its much easier to tell if you log the correct knock parameters. ;).

If you read the links below will help you understand more

Does the BPB show any gains on an OTS E85 map? Even without any changes to the map itself? Or is it a waste of time.....

In theory the bpb should shift the peak power lower in the rpm range, by shifting the volumetric efficiency. You may loose a bit of peak hp above 6500 or so, but you should still have the benefits of E85 and bpb below that.



So unless you chasing peak hp at high rpm should still be of benefit. Although shiv's comment in the first post in this thread puts a damper on that.

@nelsmar did a good writeup on them http://www.ft86club.com/forums/showt...t+power+blocks

But he was using his own tunes and on petrol but somewhere else i think he got some pretty good results on E85







.

that log was only about 20-25 miles on the fresh reflash…I'll put some more miles on it, add FLKC and FBKC, and log another pull

here, i've registered the required parameters

http://datazap.me/u/walla-walla/stag...-3rd-gear-pull

i think it doesn't appear within the 3rd gear pull, but prior to recording, on highway cruise (6th gear, 115-120km/h), i saw at least once a fl knock correction of 0.38 degree, and after the pull, still on highway cruise, i saw a few knock correction, at around 0.35 degree and 0.62 degree. so.. is it bad?

Your afr look fine fuel trims ok . The odd bit of 0.7 or so knock correction is almost inevitable. hower the -3.5 your getting at high rpm and load needs some action, either run better fuel octane booster or pull about 2 degrees out of the BASE TIMING B table for you ROM at engine loads 1.2 & 1.3 & 1.4 from 6200 to 7400 then see how it looks.
You could even try fuel from a different manufacturer as some blends are better than others

thanks!
i'm not sure i could find better fuel around the area (i'm currently using shell Vpower, wich seems to be the best we can have around here)

so, just to be sure i understand correctly, if on Base Timing B table at "1.2 engine load" at "6400rpm" i have the value 25.20, i should lower it to 23.30. is that right?

also, fl knock correction, does it means my engine knock, or that it pulled a few timing degrees to not knock?

thanks for the help, I read a few of your thread also, very helpfull, but there is so much to learn on this! :)

Yes you got it correct for table values

any flkc or fbkc knock correction means your ECU is detecting that amount of knock and then making adjustments to timing to correct the knock you logging the adjustments the ecu is making. There are limits to the correction the ecu can make.

I am learning all the time as well :)

@Malt @Shiv@Openflash @steve99

how does this one look to you guys?

Your on 93 octane fuel ? with 93 octane tune ?

reason I ask is your IAM=0.55, so its been knocking quite a bit somewhere outside that log.

Their is some positive FLKC so the ecu is returning some timing.

If that IAM has not recovered to 1, just plug in your OFT and log on screen . then it looks like you might be better on the 91 octane tune.

made the suggested correction, and it really helped!

http://datazap.me/u/walla-walla/bpb-...0&data=1-11-12

i removed 1 degree at 6 000 rpm on 1.2/1.3/1.4 load, and 2 degree at higher rpm on same load!

thanks for the help @steve99, now as I understand, it's doing great! (even if i sometime have knock correction, but it think it is not a dangerous situation under .7?)

Yes that right if its just random spikes of 0.7 or less its ok, if its consistent and at same rpm/load point it might be worth pulling 0.35 or so if your rearly keen.

every time that it knock, does it go to a "safe map" ? if so, i should better try to track down all those spikes? or is it kind of overkill to tink of that?
