Back to MembersPage/NanassyPeter


Because of the upgraded ALS code i will soon go with firmware 1.1.8.I will need some help converting the current configuration variables (1.0.53) to the latest 1.1.8.

I link the current config ASAP.


Temp sensor readings after AREF off.

IAT is somewhat acceptable.

here it is vems dot hex(would be nice a real downloadable solution in the future,remembering is not a serious solution on this i think)

http://www.vems.hu/files/MembersPage/NanassyPeter/1036_vemshex/vems.hex

note that im really not sure whats in the box.

cant really say that it reads more compared with the old unmodified ecu,now i just see the LCD versus the temp gauge.

a 7-8C less ECU reading in 90-100 range would be nice ,and would match with stock temp gauge.

thanks for the effort//pnanassy


GenBoard/VerThree

Firmware currently 1.0.30

Initial distributor config similar to MembersPage/Fero old config (he recently moved to camsync).


Please make a 1.0.35 config and tables from my current 1.0.30 mcd and mct.

http://www.vems.hu/files/MembersPage/NanassyPeter/1030_config/1.0.30_06-02-25.txt

Made .mtt files (for 1.0.35). Please review a bit in MegaTune after uploading the mtt files.


MembersPage/MattiasSandgren/VolvoPV is the engine that was tuned with 1600cc/min low-z injectors (1 for each 550cc cylinders) and aggressive turbo cams (100 hp/litre). 550cc/min injectors are no problem as long as the injectors behave identical even for short pulsewidth and you find the injector characteristics.


config - injector opening related seemed to be of critical importance in this setup

http://www.vems.hu/files/NanassyPeter/megasquirt200508011920.msq

Marcell saved the mcd output as mcd.txt, and ran perl bin/make_conf.pl global.h etc/config.txt etc/config.mtt : this compared the mcd.txt with the initial config.txt, and found some changes. Some were harmless, or good (cwl, cwh, ...). Other changes, especially the injopen-related variables, that effect operation (for the bad) that explains the untunability at low load.

Ezeket próbáltam:

If the engine runs rich even with VE=0, some or all of the following variables is too high:


It was confirmed that something between cylinders differs.

possible causes

If the misbehaving cyl moves around after each ECM reboot

If the misbehaving cyl stays even after ECM reboots. Remember, this is a distributor-setup, currently without camsync. Therefore if misbehaving cyl stays, it is very-very unlikely to be caused by ECM or ECM configuration problem.


As an experiment, flyback voltage was increased by a few diodes in the common branch, currently installed outside the ECM in the flyback wire

Will be moved inside ECM if it's justified (when a new ECM is probably made soon with 4bar MAP, since this was ordered with 2.5bar MAP)

This means raising flyback rail by appr Uflyraise=3 * 0.7V=2.1V (more like 3V at peak, though only 1.5V measured with the low current of DVM diode mode).

effective Uflyback = 1.4V (onboard, per channel) + Uflyraise (in the common branch)

Note: there is an onboard protection of D100=18V SMB transient suppression diode referenced to GND5. This is made for the sloppy guys who forget flyback: would work forever without PWM-ing (even this is not an excuse for forgetting flyback connection), but D100 probably gets overloaded at high pulsewidths with PWMing, and shorts to GND5 (injectors stay open, but FETs survive). This 18V diode limits (Uflyraise + VBatt) < 18V, which means Uflyraise < 3.5V must be maintained for VBatt=14.5V

Translate to config values (newer above):

req_fuel=11

injopen=0A

injocfuel=19

injpwm=3C

injpwmt=08

injpwm6=20

Flyback mod

Adjusting the injector-opening config and GenBoard/Manual/PowerFlyback worked. Even 16:1 AFR idle is possible now.

Moved flyback calc to GenBoard/Manual/Flyback/Calculations

Awesome work Marcell,thanks for the outstanding support!

Words cannot describe that GREAT work you did.

LOWMAP fuelcut works,highmap no100kpa also YES THAT WAS THE PROBLEM!!!Had no chance to test MATrich,but i know it will work.Im really happy that i can work with YOU!

Sajna nem tudom mit szeretnél "junkolni",ezt rád bíznám....

Here some Q:

increase the ms there?
  • yes, adjust acceleration enrichment.
