^ same here, I have only gotten to put a few pulls on the new firmware.

 

Take the bitch out to the hwy and beat on it...

 

Back from the tuner, multiple pulls and no issues (although I didn't have any with the previous motor).

There was a weird issue logging RPM. There was a gap of no data so I saved a few logs and will send it off to Haltech to have a look.

 

interesting. id like to see what Matt says when he sees that.

Anyone getting p0373 (engine position sensor). Noticed it was stored in the Ecu last week when i went to update it. Cleared it and it came back on today when a friend didnt start the car on the first push. Possible engine position sensor going bad??

 

I've had that one stored for a while too... it must have tripped one of the first times I started the car with the base map prior to my first tune. Haven't taken the time to clear it, just notice its still there every time I have the PC plugged in. Its never active, just shows that its tripped in the past.

 

I get the same thing, always when the car hiccups on cold starts. My car cranks a bit longer than it would stock, but I'm ok with that given the circumstances.

 

Ya i know the haltech takes longer to crank. But compared to the aem its twice as fast. Car lately has been feeling incredibly sluggish. Lacks power. At least according to my butt dyno. Anyone else? Btw no misfires still

 

Is there anyway to sort out the cold start issue?
How has everyone's misfiring issues been going?

 

I don't know that I really have a cold start "issue" per say... If my car cranked for 1 second before firing when I was stock, the Haltech only takes maybe 2 seconds before firing. I don't really consider that an issue.

Does anyone have any resources (besides F1 in ECU Manager, which I am reading through) that would help a tuning noob become more comfortable with making adjustments, etc? I understand easy things like target AFR graphs but still don't really grasp things like changing timing (what the change does/how it affects the tune). I'd really like to study up and become more knowledgeable on tuning because its the ONE thing on my car that I don't fully understand, and I'm a huge control freak and want to understand everything.

 

I went to amazon and looked up books on tuning. The concepts, mbt, afr, ignition, are the same. The difficulty you'll most likely encounter is navigating the menus/verb-age of each EMS.
