OFT Openflash V4 tunes released for 2017+ with Launch/FFS

[GrizzlyAlex48]

Hey I'm pretty new to the tablet and tuning in general, as well as new to the v4 tunes compared to the v2 and confused about the advanced multiplier. I am currently running stage 2+ and after 15ish min of driving my AM stays at a solid 0.70. I am running shell 93 octane and everything else seems good across the board to me atleast. Tried searching the forums to see if anyone else doesnt notice a climb from 0.70 and if it's an issue that it stays there on 93 octane. Most people seem to see theirs climb to 1.00, thanks!

Do a 3rd gear pull but slowly (70% of throttle)

Sorry for the late reply, have been at work all day. Tried doing a couple pulls on a couple different sessions of driving tonight and the highest I got it to was 0.82 however it never went under the new set value. As it went up it stayed there, I have noticed the FLKC has gone to a maximum of 1.00 at some points but have seen .72 here and there while accelerating

Not sure why IAM isn't climbing faster, but positive FLKC is good.

With iam at 0.7 is to keep it on safe side, if you have good 93+ octante fuel the iam will increase

Thank you, to the both of you, for the information. I will try another gas station and see if my logging changes at all. I appreciate it, just want to keep this beast healthy

I'm going through the same nonsense. Always put 93 in it.

When I'm cruising in the morning to work barely goes up sometimes to .84 in that range.

After work I get on it a bit more plus its warmer out. Will eventually get to .94 - 1.

Though outside temperature could have something to do with it but don't know what else determines where it goes to and how long it takes.

Going to suck at the track when you turn off the car in between sessions and it will start all over again at .7

Would be much better if it could at least remember where it left off

This is why 99.9% of the tuners provide separate tunes per fuel type and set the IAM equal to 1.

this is why you dont understand logic of advance multiplier.


it goes up when it doesnt sense knock during open loop higher load pulls, if you "cruise" in the morning trip to work and keep it low rpm low load it doesnt have a change to go up
and anyway, knock correction A map (ignition advance in Ecutek) modify timing higher loads column anyway, so it doesn t change timing in the "cruise" zone ergo you don t even need the higher timing) as soon as you push harder, if it doesn t knock it goes higher


and it s pretty obvious it s not convenient to go on track with a 0.7 IAM map
but even if you do, few minutes and it goes up, if you have good fuel for that track day


if you people can t understand how it works and why it could be convenient to have IAM at 0.7... DO NOT USE IT nobody is forcing you and nobody need your complaining


just use other things

I have mine set to start at .9 on every startup since I always use 93 octane. I live in a community with a speed limit of 25 mph. The road my community is on is a 55 mph road. My IAM will go to 1.0 about 90 percent of the time before I even shift into 6th gear and reach 55 mph when I first pull out of my community.

If it's like older Subarus then it will only advance the IAM when the advance table is greater than a certain value. Hence only at certain RPM/loads.

Exactly what I wanted to say, thanks for being specific
Normally one reach the >4.9 degrees cells on the ignition advance map during harder open loop pulls so if one just cruise to work in the morning with cold oil, IAM stays pretty there

Most tuners will assume if your getting a tune your a car enthusiast and you will run your car on premium grade fuel or the grade fuel that the tune is set for at all times.

If the tuner knows your going to do that they can set IAM to 1 and run the tune at its most aggressive ignition timing at startup.


Stock tunes are set up for the average person who maybe doesn't understand fuel types/grades and will dump in low octane fuel cause its cheaper. ie the manual says it will run on 95 so they use 95 ron cause it cheaper.

Setting the IAM to 0.7 as in standard tune slows a bit more safety margin for people who may run lower octane fuels or countries where premium fuels are not widely available. In this way at each startup the tune is in a less aggressive mode until the ecu detects minimal knock and will advance timing via IAM during driving.

It also makes it easier to do consistent dyno runs as you dont have the iam resetting to 0.7 each time you switch off car or reflash, save you having to do several runs to get iam to 1

Best thing to do if you're using 93 is to just set it to start at .9. Still safer than starting at 1, but should go to 1 pretty quickly.
