Temp related knock

I will have a look in the next few days the amount of timing adjustment is very small and may be difficult to actually see in the logs

I don't think he is down with that. If you want to mess with the tunes you'd be doing it at your own risk. People get paid big money to mess with this stuff, if you catch my drift. Just try to understand the 'what why hows' before you start changing stuff. Same goes with anything else. I do this because I like tinkering with this stuff and I have at least a basic understanding of how a car and a car's engine works. I'm learning a lot of this as I go and I fully understand/accept the risks. If you don't, then don't mess with it.

+1 on that were all learning and using open source definitions and software ie romraider, their are no guarantees here, i dont mind sharing what i discover but if you choose to use stuff guys post up here it at your own risk, like SolidONE im a tinkerer not a tuner some of these tables we alter have not been altered before ,dont expect shiv to help out when we are messing with stuff that he has not touched, just make small changes log it check the results and try again its all part of the fun and learning experience.

I understand the "what why hows", all I'm wondering is whether the percentages Steve changed in one romraider table are adding or subtracting timing, because it's not clear. Not asking for all of the secrets of the trade here. I do respect what he does though
and understand if he doesn't want to help.

the more i look at it after seeing the ecutek version i have the % table arse about,

That's exactly my plan, after I do some data logging in the next 48 hours to see if it is indeed temp related knock. I've already pulled .35 in quite a big chunk of places, if it's not temp related I'll be pulling .35 more where it needs it. Will share my findings, hopefully it will guide some people using socal 91 gas.

Mate that was a stock A01G ROM in ECUtek, open the same in RomRaider and post the table. That should be an easy confirmation


*EDIT* - Just checked a B01C in RR and it has -100% where ECUtek is 0 and 0% where ECUtek is 1.

and 0% where ECUtek is 1.

This is stock tables in A01G

So RED would mean more compensation (more timing pulled)?

Nicely confirms my idea, RR is a bit arse about face. -100% is 0 correction applied.

Yes, spot on. 0% is full correction applied.

Okay thats what I thought. I was looking at the -100% thinking hmm..why would there be more timing pulled at much lower engine load.

[steve99]

Looks pretty convincing , @Td-d could you look at the scaling on that table for temp compensation please

[Td-d]

Guys - I know Ecutek is awesome and all, but this scaling has been on the IAT activation tables used on Subarus for time immemorial. Maybe I'm just used to reading it, but -100% makes sense to me - 100% of the compensation is removed, in other words no compensation is applied. 0 means none of the compensation is removed.
