Hi,

is there a way to lookup / comment on current tickets aside from via email?

I submitted a ticket (#18821) on the 30th but haven't received a reply, just wanted to make sure it hasn't been...

thanks. that was it. coolant redline modifier. missed it as I was going over the cutoff/dfco stuff.

Thanks Schpenxel!

yeah. ETC% is 100%, so I'm good there.

still cutting at 6k. I'll keep digging.

ok. closer.

not sure exactly what fixed the throttle limiting but I:

set number of active cams to 0 (its got an aftermarket cam)
maxed out the various torque limits in torque management

so...

Ok,

I downloaded the 2.25 beta. as advertised it exposed some DTCs I needed to kill, namely shift solenoids and things of that nature.

with all of that (sess disabled, no error reported)...

I've emailed HPT for a link to the beta. I'll give that a shot.

Schpenxel: this file is mostly stock aside from some idle changes and DTC stuff. its probably not hitting PE due to limp mode...

Hey guys,

I haven't done many gen4 PCMs yet, first one bolted to my engine dyno this week and I'm having trouble disabling some of the DTCs so that it doesn't throttle limit on me with the trans...

I should add that if I disable the iac motor and reduce the throttle screw to make up for the rest position of the iac motor I can easily idle the engine at 1k with foot control. the iac just seems...

Hi,

I'm working with a customer on a motor I dyno tuned. the fueling at low rpm is good (1.0 lambda) but I cannot for the life of me get a stable idle. Its a cammed motor, so I'm targeting...

yeah, I mis-spoke(typed). I scaled both down. I'll edit the original post.

transient fuel mg, I dont think I've futzed with that. thanks for the tip, I'll play with that next.

Just a followup on this. the cut I was experiencing was 1514 max calc airflow. I had the table maxed out, but due to the huge injectors on this thing the pcm was exceeding the max values on the...

ok thanks, that did work (the magic bullet was using 0 for the shift speed instead of 255 to disable in a couple of spots). next issue is I'm still getting some kind of limp mode. this one happens...

not sure. I can ask the owner if it matters. I'd think since I have the shift speed values maxed the accuracy of the speedometer shouldn't matter. but, the numbers seem plausible on the vss...

its a mega truck built for mud racing. its currently strapped to my axle hub dyno so the tire size is sort of irrelevant. trans is a built 4L80, unsure of the stall rpm but I'll find...

I just want to disable power enrich and have it all be controlled by the VE table. I've had issues in the past with it being unpredictable with regards to how the PE enables and when, so I find it...

here is another log with 106 disabled, still cutting (tried no error reported as well as sess disabled). this log is also with reduced PID count.

and no, there is no 106 code being...

Hi,

I've got a gen 3 ecm vehicle on the dyno with a 2 bar speed density operating system and the MAF fully deleted (unplugged, not in the system at all, and near as I can tell properly failed in...

will do.

I believe I tried that and wound up with the same behavior but I'll double check. thanks.

Hi,

I have a 2bar SD OS, MAF fail high set to 0. engine runs fine with the MAF plugged in. we plan on completely removing the maf, so we've wired in a separate IAT which reads fine in the vcm...

so, looks like I'm on my own here? I guess I can give it another shot on 2 bar SD, but I've got a decent amount of time into the fueling and idle on the 1bar OS. there has gotta be something simple...

I tried using the 2bar supposedly SD tune but it was somehow still using values from the MAF despite failing it correctly in the software, which is why I reverted back to using the 1bar standard OS....

I have not modified the spark histogram. I only added a wideband o2 and air temp histogram at item #10 and #11.


also I forgot to mention the vehicle has a 2bar map sensor installed.

It must...
