I have a 2002 swapped 5.3 and a 24x conversion done on two of my vehicles. I'm wondering if there is a way to get my ecm to see when I turn on the ac to idle the engine up? ive read and wired up what...

Sounds like your going to spend 100$ any way you go..

Why do you need the vin the same? I would think your could copy a stock tune to that ecm getting rid of the express files all together. Just my thoughts tho.

Hey I'm using a 411 truck ecm in my 24x conversion. Have you gotten the efans to come on when ac has requested them to through the ecm? I've read once somewhere that you couldn't do it in the truck...

That makes a lot of sense. I do know to make peak power you need a dyno. I'm just trying to get a idea on what are some way to adjust the timing what the pros do when they, lets say if they do a...

I did read the same thing somewhere myself. There has to be another way I mean not everyone has access to one.

Trying to learn what the best and proper way to adjust the main timing table. I've been doing some searching and can't find a solid answer on how it's done. Do you log spark advance if you do what do...

its the pedal if I shove the pedal through the floor it goes to 100 ill need to address that.

Hello all I this is my first tune its on a 5.3 swapped k5 blazer. Ive raised the timing some and disabled all torque management. I'm showing 0 KR so I think I can raise timing more just need the...

Oh so your saying when it goes it to closed loop it's commanding a different idle speed? I mean that makes sense if so because after the engin warms up and you restart it, it will be and 600 and in...

Okay thanks your doing pretty good I think. Like I said I'm a noob and trying to learn what I can. I'll fix that in the tune. Thanks for explaining it tho.

Oh ok now I understand.

ohhh now I see why the stock tables looked something like that. so the rpm on top of the table is- if its over or under target idle it adds or takes away that amount of timing? maybe I didn't...

Also I did not tune this engine. I had someone else off this forum tune it over the web, and they wasn't much help so I'm trying to fix the issues I have, my self now.

Oh crap I forgot to say what engine I have it is a sbc gen 1 with a cam running a 24x conversion. It's not a lt1 tho im using the LS throttle body on a edelbrock efi intake.. Im trying to learn to...

I'm a noob here. But how are you using that pcm with the old 5.7 vortec engine harness?

So has anyone figured out the KR and how to get to read correctly.
I'm showing no KR now and by what ive read I need to get a van sensor and ditch he LT1 sensor. it would be nice to be able to dial...

OP Is this a 24x conversion??? I see your using the 411pcm

okay I attached a log and a tune file I have it set at 600 in the tune file to make it idle at 700

when I set my desired idle to say 700rpms and crank the engine it idles at that rpm for a min or so and then it slowly climbs up another 100rpms. I can see the desired idle in the scanner showing 700...

Hello all I'm really new to the tuning word. I have the 1st course of The Tunning School at home learning course. But I'm needing to check my open loop AFR I have a bad dead spot when the engine is...

Hey guys I've been having a issue with my 24x conversion. I'm not picking up KR at all. I drilled and tapped the block right behind the drivers head and installed a new sensor. I've checked the...

how do I install the drivers for the interface in windows 10?
I just bought a new computer and I was running windows 7 before so any help would be appreciated

I'm needing help with a start up tune on my 24x conversion in my v8 s10. I'm using the 99-03 truck pcm I've already moved the coil and injectors pins to correct the firing order difference. the...
