Temperature problem and engine goes very rich!
Temperature problem and engine goes very rich!
If i run the engine in Idle and warm up, the ECT temp goes up to 98 °C, until the fan switch on.
In addition, the engine already runs very rich at in idle.
I mean it was not the case in earlier versions (software/firmware)
At this time, the fan switch on: Engine goes very rich at idle: I sent you the calibration by email to support@hondata.com
All connections, hoses etc. were checked for leakage and are ok.
I have these problems only since the last software / firmware versions.
Thanks for help!

Re: Temperature problem and engine goes very rich!
What is wrong with an engine temperature of 98C at idle?
There's no indication that the fueling has changed in recent version but we will look at your calibration.

Re: Temperature problem and engine goes very rich!
Before the Software and Firmware update, my s.trim was at ~-5!
Also in normal driving, the s.trim is now very rich at ~ -16!
Or is this a indication for a bad O2-senor?

Re: Temperature problem and engine goes very rich!
The best thing to do is to compare the injector duration in datalogs from before and after.

Hi Hondata,
I will support him.
In the attachment you will find the requested screens.

Thank you typer86 (Jerome)!
Hondata, what do you think about this issue?
I need a quick solution, because I need the car every day!

Re: Temperature problem and engine goes very rich!
Now i have tested the new Version 2.7.8.0, but the engine goes very, very rich alone in idle up to -20 on cold start:
The engine/engine bay shalls very quick hot!

Now, i have tested with 13% leaner afm-fuel looks like this:

Re: Temperature problem and engine goes very rich!
I have tested your calibration with 2.7.6, 2.7.7 & 2.7.8 and they all run the same, with fuel trims < 10%. I had to change the MAP sensor setting, injector size, AFM conversion and injector table.

Re: Temperature problem and engine goes very rich!
What could be the reason, why now the Map run so rich on my vehicle?

Re: Temperature problem and engine goes very rich!
I'm not sure. I'm waiting to see if there are any other reports of problems with the FG or FN2 before going any further.

Re: Temperature problem and engine goes very rich!
The curious thing about this problem is, that WOT (is still the same), but only the afm-fuel was too rich.
I had to go 10-12% leaner in afm-fuel, to reach the previous values.
Could the problem be related to the changes for my Flashpro, because of the following datalog-problem, which I had:
https://www.hondata.com/forum/viewtopic ... 28&t=20439
I mean, that it is only since these changes.
Or could it have something to do with my ASNU-injectors and/or a software change regarding to Hondata?

Re: Temperature problem and engine goes very rich!
We've made no changes to the FN2 for a while. The problem in the link you posted was related to the FlashPro, which is independent to what gets uploaded into the ECU. I'm not discounting a software problem, but at the moment it is isolated to yourself. typer86 - did anything change?

Re: Temperature problem and engine goes very rich!
I have checked the prev. calibrations which no changes are made in AFMfuel or injector opening time/VTC Profil.Hondata wrote: ↑Mon Jul 03, 2017 8:26 am We've made no changes to the FN2 for a while.

So Im really have not idea what is happen very strange thing.
I have reduce approx. 11% AFMfuel timing to keep S.TRIM OK again. Currently we do a short retune which is finally finished today or tomorrow...

Now, if I compare the same Hybrid-Map from the version 2.8.1.0 and 2.8.2.0, the engine now runs too lean!R-12914 wrote: ↑Mon Jul 03, 2017 7:55 am The curious thing about this problem is, that WOT (is still the same), but only the afm-fuel was too rich.
