Fuel/Spark tuning for LH 2.4/EZK with TunerPro! - Page 94

EFbI4 · 02-08-2021, 02:56 PM

Finally I'm tryed to live tune LH ECU and... There is something wrong basically.
I disable lambda regulation, upload my firmware, adjust AFR on idle, low loads and high load. But how to adjust medium loads? I can't find a good recipe for it. Maybe you there can give me some advices?
In TunerPro I can't find a logging for RPM/LOAD table (mail fuel map) and I have no idea how to log tracing (and as we know trace is slow and sometime wrong).

Hi

LH can absolutely not be "live tuned" per se !

You can actually fry the ECU by changing parameters with engine running.
It is not possible to log the tracing in Tunerpro until someone makes a plugin for that.

Tuning of medium loads is same as all other LH tuning, it is primarily done in the main fuelmap.

Perhaps I'm misunderstanding, but I've been able to live tune using the Ostrich, and upload the tune to the ostrich while the engine is running.

I have been able to do it most of the time too, but 0.01% of the time the car will royally **** itself and flood or crash the computer or go into weird unknown states. I don't do it anymore

I've had it crash the ECU but not anything weirder than that.

Just a quick Update!

Sometimes things are not as they seem... I found the Issue. The FPR was faulty and it pumped fuel right in the Intake... Fixed that, and now it is running like it should! Thank you all!

And yes TÜV is only once all 2 years =)

Finally got my junk on the dyno, using kyle's (klr142) every day mapping as part of the setup, in a later bin file with the e-fan compatibility. I also updated to include the later lambda constants, as I made a comparison sheet for those. The tune got put in a 984 casing and ran on the dyno for a cool 135whp@190Nm. 1500-2000 rpm needs some sorting, possibly some idle enrichment deal that could be improved, in general I'm happy.

To repeat a small summary of the setup for reference:
10.3:1 b230k with stock 530 head
kg004 aka k camshaft
buchka wasted spark
218cc ev6 injectors
bigger J-pipe with turbo exhaust system
Chipped lh2.4 (own tune)
