I had a problem with O2 correction swinging wildly after a firmware upgrade recently. Haltech advised to zero out the Differential table in the O2 setup. All ok now. But for cold compensation, see the Haltech Youtube video on cold start settings. Matt suggests the only compensation needed is to setu...

Have you checked the voltage at pin b11, that's power in to the ecu. If that is ok, then contact Haltech.

I think the same is true for pin 26 on the PDM.

Suggest you watch the Haltech Youtube channel video on cold start settings. The prime pulse is doing it's thing and getting an initial fire, the follow up settings such as after stat are too lean to continue firing. Additionally, do a log and observe what the idle air control valve is doing to hold ...

What worked for me is to have the phone forget the device then key on the ecu. Phone should search and find the device, enter the password and it connects. I had to do this on future connects, don't know why but it did.

Examine the calibration files you are seeing -100 to 200 and you may see that the units are not absolute, but kPa and is the same as 0-300 kpa Absolute. As an experiment load one of those calibrations, view the cal data/curve. If your Preferred Units are kPa Absolute, the y-axis scale will be 0-300....

I noticed a constant current draw to the controller with key off, so I installed a controller main power relay.

My limited knowledge is info what I read on the EFI101 board quite a while ago from the person that was on the design team at Electromotive EFI that invented the crank trigger wheel concept. What he said is that on a very fast reving engine , i.e. high rpm change per second.increase, the 60-2 was be...

I can't find the test either. I looked in the software change description and nothing about it there either.

What's "this", the firmware or the test?

Yes, All that's needed a +12 on B11 and ground.

Help/Keyboard reference - the 2 keys to the left of the Enter key do the same as PgUp/PgDn

For an ignorant user, what is "Throttle Mass Tuning"?

Connect and the map that is in the ECU will be dowloaded to your laptop.

zip the files and they will upload
