Thanks for taking a look and the tips. The fuel pressure is stock, I used a mercruiser cool fuel module and put an adjustable fuel pressure regulator on it. I figure I will put the wideband on and...

I didn`t see much posted in the way of boat tunes and someone contacted me looking for a base tune so I figured I would post this up. It is a stock 2007 LQ4 6.0L with drive by wire...

I figured out why my fans would not engage.

My A/C Fans Disable speed was set to 0mph. I did not think this was a problem as the HPTuners description states "A/C Fans Disable speed: If the AC is...

I was able to trick the pcm into checking the ethanol content every time it starts up. I used a timedelay relay and resistors to simulate an almost full tank at startup and it drops down to below...

Well after spending hours playing with HPTuners and a tech 2 I have found that the A/C request switch feature only partially works. You don`t have as much capability to change the A/C request type...

Yep its in a 1978 buick so the fuel sender will not hook up as the ohm range is 0-90 instead of the newer (40-240 iirc?). I didn`t want to try doing a full tech 2 reflash as I have a clone tech 2 so...

Well I figured out why the PCM was stuck on 43%. Turns out the PCM needs to see an increase in fuel level before it will check the ethanol sensor even in the systems with the physical ethanol...

Yep I`m running fuel through the sensors to test them and isopropyl alcohol to test for alcohol content. The hz output of both sensors varies depending on if the sensor has e10 pumpgas, is empty, or...

Well I finally had a little bit of time to play with the car again. I grabbed the flex fuel sensor off another car and hooked it in. When I hooked it in I was able to get the tech 2 to register...

So I believe that I have a bad flex fuel sensor as my commanded afr is around 12.2 when warm and operating in closed loop. My Alcohol percent is stuck at 43% and the sensor was putting out a 92 hz...

It might be my wideband. The grounds and wiring are all good, but I can`t seem to plug into the LC-1 with a laptop. I updated my laptop since the last time I plugged in to it and my new laptop does...

I`m running an innovate LC-1 wideband 0-5v 7.35-22.39AFR. I did the calibration on the sensor per the innovate instructions, but I guess that I can`t say I have ever calibrated it to anything else. ...

What do your 4 main timing tables look like? any big jumps in spark advance between them? If there are large differences in advance between the high/low octane tables and the base spark vs airmass...

Where are you pulling your air in from? How close is your MAF/IAT to your exhaust. By your log it definitely looks like your IAT gets heatsoaked air low speed / idle. My first thought is that your...

I am logging my wideband through the fuel tank pressure sensor. All of the data comes up and populates the hisotgram ok. The problem comes in when I copy it and paste special multiply it into the ve...

On my last scan I did notice that I always seem to be in fuel trim cell 22 could that be part of the issue? what would cause me to be stuck there?

Ok, I figured out why the filter in the WB AFR did not work, I copied it off a histogram I downloaded and it had a > sign when it should have been <. I still can`t get the VE table to be consistent...

The rest of the scans

I`m kind of a newb when it comes to tuning as all I have done before was my 0411 pcm`ed 6.0l el camino and I remember taking forever to get the ve table close enough for me to accept it.

Now I`m...

I have been looking into this a little bit and heres what I have come up with for our options.

I`m not sure what would use the serial option but I believe thats a serial data request and a...

Thank you!

Does rolling idle enable to idle adaptive spark control over/under speed tables while the car is moving?

I have a 6.0L with a GM hot cam and a stock stall torque convertor and I have been fighting...

I have a beta release and it does not have this feature. I again requested it via e-mail a couple weeks ago, but haven`t heard back. Tunercat is the only one that I have heard of having it in their...

:hi: Any updates? I still need to hook up the A/C on a 2003 swap.

+1 I really would like to run the a/c on my swap through the PCM without having to hack in the BCM.
