Hey guys,

I'm trying to write a tune for a friends '99 5.3L that is swapped into an '02 S10 and am not able to write to the PCM. I can read the PCM fine and scan everything as well but every time...

Ended up fixing the speed issue using the segment swapper. Everything works great now and get all gears.

Still waiting to hear Bakker about the controller unlocker message though but no rush now

Is this suppose to be just as easy for the other way around, from an ECM that use to be matched with a manual trans and getting it to work with an automatic?

I originally had an LY6 matched to a...

Hey guys,

I'm in the process of swapping out my LY6 for an LS3 and I am having communication issues between my new ECM and the TCM. The transmission is a 6L90e from a 2008 Silverado and the LS3 is...

What I'm afraid of now is that I corrupted my original ECM from the LY6, I was able to read vehicle speed from that ECM and everything worked fine, I just needed to make some adjustments to the tune...

I figured that was one of the things that HP tuners can do, is reprogram the ECM and TCM to be able to operate both. That's why there's a Manuel and Automatic option. Unless I'm completely mistaken?...

Does anyone know if Pin #18 in the J1 connector may be my issue?

In the pinout instructions for the LY6 harness it states to remove that pin, in the LS3 pinout instructions they state that it "May...

I tried everything in this thread with no luck unfortunately. I have sent an email to support, just waiting on a reply.

I have emailed them, waiting on a response and hoping they are able to help me out.

Now it seems like my idea to use my original ECM that cam with the 6L90e isn't an option. Every time I try to write a new tune to my original ECM I get this message... "Controller unlocker: x36...

Now every time I try to write a new tune to my original ECM I get this message... "Controller unlocker: x36 exceeds number of attempts". I am not able to make any changes at all to that ECM and the...

When I try to write a new tune I get "Controller unlocker: x36 exceeds number of attempts". This is the same ECM that I purchased credits for myself and have tuned multiple times. Why is this...

Hey guys, I know this thread hasn't popped up in a while but I am now having this issues. When I try to write a new tune I get "Controller unlocker: x36 exceeds number of attempts". This is the same...

So the part number on the MAP sensor is 12591290

The ECM has the option to select a manual or Automatic transmission. Would that not mean that it can work with whichever type of transmission you choose and then that speaks to the Valvebody TCM that...

Thanks again 5FDP.

I'm back at the shop tomorrow during the day before starting my nightshift so I will have a look at the MAP sensor part number before changing anything. Hopefully I can figure...

I already purchased the licence for the new ECM so that's not an issue. I tried copying over the data to the old ECM which made it so that the transmission works but the engine didn't run well at all.

Sorry, I don't understand what you mean by this at all. is it possible to elaborate?

Hey guys, I recently swapped an LS3 into my Cutlass to replace the LY6 that let go on me on boxing day (Merry Christmas right...). The transmission that was matched to the LY6 is a 6L90e, and I am...

I wan't to start with saying thank you for attempting to help me with this issue, I appreciate the help very much and hope this leads to me fixing the issues I am having.

That's what I originally...

Now I'm not able to write anything to the ECM. I keep getting a failed message: "Controller unlocker: x36 exceeds number of attempts"

OK, I'm not very familiar with how to change the Airflow model with the e38 ECMs. That's why I took the LS3 ECM in hopes that I wouldn't have to mess around with the tuning for the engine and was...

This engine has a cam in it from what I'm told. Would I still be able to input the stock MAF and MAP sensor settings?

I am using the Camaro MAP and MAF sensors. I changed the pins in the MAF connector to accommodate the new card style sensor along with adding the proper pigtail for the Camaro MAP sensor.
