Hey Bill, I have another question.,,
I just received an email about the new MPVI3 interface. Will this interface allow me to read/modify/write my PCM & TCM without having to use an offboard? ...
I just receive an email about the new HPTuner 5.0. Will the release let me read/write my truck using the OBDII connector? If not, is there any intention of developing this ability?
For anyone interested, this didn't work. I disconnected the X2 connector from the security module (this connector contains the 2 high speed network wires to the PCM: CAN + and CAN -) and connected a...
Bump
Has anyone tried to tap into the network without taking the PCM offboard? For example, looking at my network diagram (2021 Colorado Diesel), the GMLAN bus runs from one module with a terminating...
Well shit. I wish I would have known that.
Can I flash the modules through the DLC?
I got it, it went to another email account...
The email was from Chris Martinez (HP Tuners) and first line was "Your request (56986) has been updated. To add additional comments, reply to this...
Thank you. I don't understand why, but I can't see the email I received last night here at work so I don't know the ticket number. I'll get that to you when I get home tonight.
It looks like the...
When using an offboard, does anyone know what pins to use on the PCM? I looked in the 'OBD-I & OBD-II Hardware And Communications' section but didn't see anything there. I'm curious if you tapped...
What were you doing when each of the commands was recorded?
... but then again, the OBDII connector doesn't connect directly to the network, so never mind...
Thank you. Do you know where the security block is coming from? If you have to use a bench harness to read the PCM, I'm guessing it's from the gateway module. I see a terminating resistor in the...
Do you know which pins the HPTuner interface uses to read this PCM? Which network it uses? How would I find out?
??? Where do I get one of those? Will I not be able to modify the transmission computer? That's what I bought it for - modifying the transmission computer.
I received the new interface today, but was unable to read the PCM on my 2021 Colorado. I sent an email to HPT support, but didn't know what else they might need.
I downloaded and installed the...
Got it, Thanks!!
Yep, that's what I meant, thanks!!
One more question and I'll leave you alone. I send the interfaces I have (the MPVI I have now and the MPVI2 I'll purchase from another vendor) back to HPT,...
So, that being said, if I purchased in interface from another vendor, and send you my MPVI pro interface for upgrade, is the Pro option flashed to the interface or is a different interface all...
Hey Bill, one more question. I've been going back and forth with my dealer trying to fix a transmission problem in the above mentioned truck. I think they are going to replace the transmission...
OK. Does my current interface have any kind of trade-in value? Not sure if y'all do that or not. Also, would the credits I have with my current interface transfer over to the new one? I have a...
Hello. I have a 2021 Chevrolet Colorado 2.8 liter and may need to modify my transmission calibration. Can I do this using my MPVI? I purchased this years ago for use with my 1998 Grand Prix and...
Been a loooong time since I've been here, hope anyone who remembers me is still good... I recently bought my old 1998 Grand Prix back, and all my old tuning files are in *.bin format from when I...
I have done much to my 1998 GTP in the way of tuning, but have never tuned anything else. I just bought a 2007 Dodge Dakota and wanted to start tweaking, but I'm not sure there is anything to gain...
