Read HPTuners Tune with EFILive. 2 Bar

[Black LS1 T/A]

Looks like it's time to scale the airflow tables for idle.

Well ... since he has piped in, I guess I shall say "Thank You" to another extremely knowledgeable Tuner/Programmer.

One of the "gotcha's" that plagued me was after the 2-Bar MAP sensor was put on the vehicle, I did not know about the MAP Scaler parameter. Chatting with A.J. about my situation, and the fueling problem I was having, he almost immediately homed in on one of my problems. He asked me had I scaled the MAP sensor to the new 2-Bar. {crickets} So, after he delivered a method that looks like it fixed my gas tank gauge (It is no longer pegged full nor empty), I set the MAP Scaler to twice the stock value and I read atmosphere. I hadn't even checked the Static MAP value. :*(

So, when I am done, you will see a detailed list of issues resolved and gaffes on my part to be avoided.

Hope it helps someone ...

I know AJ

Glad you got it running... so now we'll have to do various tuning

First, did you want to get your PLX doing serial comms with FSV2...?

Yes sir!



The 3.5 stereo mini plug has a Y-Splitter so the serial signal can go to the gauge and another device like the V2.

I assume I could jack it in with something like this and the straight cable they supply, but so far all I've found are 2.5 mm, not 3.5

Do you have the PLX user manual pdf (I probably asked before, but I don't remember)...?

Wait ... I found this. But, I STILL don't know if it's wired the way it needs to be:

That looks like it only has 4 terminals at the RJ9/10 end...

You want RJ11/12...

You could probably modify that cable (remove the RJ10 and crimp an RJ12 on).

You would have to experiment, crossing Rx and Tx, to which what works (V2 has to be plugged into an OBD2 port).

Looks like it will do serial comms, page 2 shows a diagram showing Rx/Tx...

I can't tell from here...

if you can connect the PLX to a PC via serial comms and talk to it from the PC, then you need the null modem functionality (i.e. swapping Rx and Tx).
