Hondata

I am having some engine work done (full engine out) and before I get it done I want to unlock the flashpro from my ECU in case something goes horribly wrong with the engine work I want to make sure I am still able to still use the flashpro in the future.

Assuming everything goes well with the ...

says the file(s) are too large. the max is 20MiB?
But the data log is 500,000 KB?

every now and then the Flashpro will create a corrupted logfile that's huge (like 500MB or more). It seems to be a bug or glitch that has persisted for years. I just delete those when I see them in the list because ...

I checked it myself with just using a baseline calibration and then altering it (these files are attached). The compare function in 4.7.6 shows no differences at all. (no screenshot attached, because it's literally an empty table of output on 4.7.6)

On an earlier version of FPM, it shows this ...

By the way, for context, I am running the Hondata Fuel System Plus (with the fuel lobe camshaft) and Hondata 2000cc injectors with a Sirimoto flex fuel system.

I have not had these issues in the past with the 1330cc or 1530cc Hondata injectors but I also almost never ran much more than e60 on ...

Over the winter I had some strange cold start issues with a high ethanol content (>70%). I managed to sort those out for the most part by adjusting the Ethanol fuel adjustment (ECT) and (number of injections) tables.

Now in the hot summer where we're seeing ambient temps in the mid to upper 80s ...

it works okay in a virtual machine but it's slow and can be glitchy (apple m4 pro chip). maybe on intel hardware it would be better in a VM.

As Caustic Gnostic pointed out, your KFMIRL/KFMIOP tables are not in agreement. Correct that first and then see if you still have the issue.

I'm not sure exactly when it happened but some time after FPM 4.6.2 we lost the ability to view all of the torque channels that are being logged. I have to keep a copy of 4.6.2 running in a virtual machine just so I can view my logs and this is very inconvenient.

these are the channels that went ...

Please add boost by gear limits. I assume this is possible since this table exists in the Accord 2.0T calibrations. It would be ideal if the table covered all 10 gears instead of just the first 6, but I'll take what I can get.

can you post the mods you have on your car? Intake, exhaust, header (cat, etc)? I see you have a MAF-based tune enabled in your calibration. If you're using an aftermarket intake this is probably why your lambda readings are off by so much

Thanks!


I am not real familiar with tuning on that 9th-gen platform but I'm wondering why there is a 15% overall fuel trim added in the Fuel settings of the calibration that you've uploaded. Generally that should be set to zero on a flex tune *if you have everything else ...

With your FlashPro connected to your computer (the FlashPro can be, but doesn't need to be connected to the vehicle for this), from the FlashPro Manager software, click the "FlashPro" button in the toolbar. This should pop up the "FlashPro" window. On the Flashpro window, click the "Calibrations ...

When I tune the MAF on the FL5, should I refer to the short-term fuel trim (STFT Geometry Dash ) or the total fuel trim value?


You should use Total Fuel Trim (STFT + LTFT) as your main reference when adjusting the MAF curve.

I tried, but from the logs I found that the short-term fuel trim ...

I just had a quick look at your logs. Yes your fuel pump is spending a bit of time in the 90s around the torque peak, but your fuel rail pressure and lambdas are staying close enough to their commanded values that I'm not seeing a critical issue in these logs. Yes there is a brief moment around ...
