Did a log of my cold start this morning to get a better idea of the resonance. Noticed that the ignition timing during that time is -8 and then moves to +20 when the resonance goes away. I am now more than sure that this is related to heating the cat on cold start. Looking into the tables, I found a table that apparently is for Timing after start. The values in that table are negative and I assume they would modify global timing to be significantly retarded. You might want to reduce the negative number in those tables say from -15 to -5. I think that would solve the resonance, but would it negatively impact something else I don't know.

Also the temp vs maf is in g/s?

Do you have the link in romraider you mentioned....I've been searching their forums and only find older info.

The OFT is great for this platform with the available OTS map. These cars are NA so there are much less components that can cause issues like the 335i. Common issues with fuel pump, injectors, spark plugs, and etc are not common on these FRS/BRZ.

We are sold hundreds of tablets as of today and the results are super consistent. Even though 15whp and 12wtq doesn't sound like much in the n54 world, but it sure makes a whole lot of difference on this FA20.

Any questions feel free to let us know.

OFT Price Difference - FRS vs 335i

Hey Shiv/Robert,

Just curious, but what is the reason behind the $100 price difference for the OFT between the FRS ($495) and the n54 333i ($395)?

Hopefully I will be picking one up next month

Thanks!

To save them the time I can let you know it's to recoup the cost of developing it for this vehicle.

My first experiment was raising the idle in all of those tables to 2000 for everything below 50°F. That did work, however I think your right. There is more at play in the early morning resonance. Retarded timing and possibly early exhaust valve opening would make a lot of this noise trying to warm our non-existent catalysts.

Do we need a new thread to share research on this?

Yes, this is the cat light off strategy, retarded timing (and probably late injection) heats the cat more quickly. Messing with the target idle in this area or the after start ignition timing is likely to cause a CEL.

In the past i tried setting the after start timing to 0 rather than -10, but that resulted in large cold start idle speed target errors, a higher cold start idle speed, and a longer wait time before it exits the cold start loop. It did reduce the volume level a little bit though.

Either not all the cold start logic tables are defined yet, or the cold start logic is not exposed to table inputs.

Can somebody please explain to me how this product can help prevent DI seal failure? How do the seals fail exaclty with the stock rom and how does the OFT take measure to correct it?

Thanks

Check out this post: http://www.ft86club.com/forums/showp...48&postcount=5

Particularly this line: The fix in calibration A01 is to move the upper bound remit of the transient spark table from 5200 rpm to 10000rpm (e.g. always) and the actual table itself has been populated with some meaningful spark angles so it does its job up top now its actually activated.

My understanding is that all of the shelf tunes for the OFT have this modified transient spark table.

I experimented again by just setting that timing retard after start to -5 from -15.
I got a higher cold idle, CEL and P050B code. But it is still much quieter
I'll try it again with something in between

Hey guys,

My car is on 1.34b and it experiencing idle dip. When I'm on the break back down to zero the car's RPM will dip for a split second to 500 causing the car to jerk a little. Is this normal? Can I fix it? Do I have to reflash and bring into toyota.

I have stock air intake and evo 3 exhaust.
