I setup alerts on OFT yesterday and noticed the IAM alert going off while driving on the highway. Normal street driving was fine, this was just on the highway.

IAM drops to .98, FLCK hits -1.2 and -1.3

Cheers!

Looks like your getting some knock, You need to tell OFT to log ignition adv. can't tell much with out it.

Thanks jvincent!

No probs, I'll log ignition adv. when I have the chance. Thanks oldgunfan!

So I compared the OTS stg 2 to the new stg 2 rom modified by shiv that enabled the MAFv and IAM readings. I seen that there were additional tables from the modified version and there were a couple of changed tables. It looks like he used the new OFH rom but applied the OTS stg 2 values into it but not quite all of it. There were a couple of tables with the modified rom with identical values as the OFH but different from the OTS stg 2 rom for example "Manifold Pressure Sensor Limits (CEL). What I did was copied the values from the original OTS Stg 2 to the Modified rom. Basically I copied over every single value from the the original OTS stg 2 to the modified rom but did not touch any other parameters that was identical with the modified rom and the OFH rom (I guess the additional parameters that were missing in the older OTS stg is what allows the OFT to read IAM and MAFv etc) I hope I'm making sense because I'm having a hard time making sense to my self the using the proper terminology aswell lol

So every table that both the original OTS and the Modified had in common I took the values form the OTS and paste it in the modified rom (modified rom had identical values as the OFH) All the new tables or parameters what ever is the correct term that are in the new OFH and the rom shiv modified that are missing in the old OTS I had left untouched.

Now, do you guys think it is safe to flash this edited rom to my car?

Yes wayno tunes include the low midrange tweaks but are far less agressive top end as they are for our 98 ron fuel which is about your 91.

correct you wont be able to load them directly but you can copy the tables accross in romraider

Their is no way i can say yes, as i have no idea whats been done, dont take rom editing lightly, a single mistake can cause car to run erraticly or brick ecu. Somtimes oft guys modify roms internally to change calid.

Ill say this unless you know the effect of all the tables you changed and your confident that you made no mistakes and you used the correct defs for the roms as different tune versions require different defs even though the name or calid appers equal. If you did not check the roms with a hex editor to see if it was calid adjusted, and checked all the source and destination tables to see the axis and scaling was correct, i would say no dont flash it

You need to talk to steve99 or Wayno they know everything about Australian fuel and how to make these GT-86 engine's run on it

So after fiddle-faddling with the OFH beta maps for a while, I ended up porting all of the tables from the OFH beta map into an existing modified map that I've been using with slightly modified DI/PI tables, among other things.

http://datazap.me/u/jawn/ofh-maps

There's a tiny bit of FLKC at the end there, but it's seemingly not consistent. Let me know if you see anything of concern. I know I should probably scale my MAF a little bit.

This is with the Gruppe-S header.

You didn't log one of the most important parts KNOCK CORR. how can you tell if you have engine knock without it. other than that it looks like its running rich at WOT and really erratic.

Don't bother logging FBKC.

Yeah, they've been heaps helpful. Actually running Wanyo's UEL 98ron tune. Which is super smooth, just starting out with alerts and logging, so lots of learning to do still.

I guess I really need a custom tune or our 91 gas is shit. Just did a short drive around no hard pulls just cruise. Is my car running shitty?

Looks like you're getting a good amount of knock under high load at low RPMs. 91 octane is shit, but high load at low RPM is also a good recipe for knock.

Either that or not all the altered knock correction values have been copied to your rom and it's using the stock values which over-correct on knock.

Since when is 0.6g/rev high load?
