    MAP Sensor reading low

    So I’ve checked voltage with truck off key on with the sensor unplugged. The orange/black wire it’s was 4.86volts. The light green was 4.96 volts. I don’t know if that means anything? I also got a stock tune file and flashed it and the reading stayed the same. So tune is not the problem it looks...

    MAP Sensor reading low

    Yes I did change tunes to Danville at the same time. But I didn’t save a readout because it already had tunes from another company on it and was told not to read the ecm before flashing. I’ve talked to mark and he said it’s not the tune. I’ll check voltages

    MAP Sensor reading low

    I don’t have the stock tune as it already had tunes from Another tuner on it when I bought it

    MAP Sensor reading low

    I’m having a problem with my map sensor reading low. It’s reading about 11.7psi. Baro is around 14.2 psi. The truck seems low on power and the turbo vanes are closed up to 90% most of the time. The problem started after I installed a bunch of parts. Danville turbo and tunes, wcfab piping, and...

    Pilot inject at hot idle is 8 and main is 2 So you 320-350 compression shouldn’t make it smoke and haze at “cold” start up?

    pilot at cold start is 13-14 degrees. And do you mean main injection timing? If so it’s 4 degrees at cold start

    Was originally at 4400psi and got bumped to 6500. It did seem to help alittle but still hazes at 6500

    So MAF reading is figured out. Just wasnt calibrated right. Idles pretty smooth. Still fighting the haze/blue smoke. Thought it was kinda fixed but it got down to 55-60 degrees in the morning last week and the truck smoked blue bad and seemed to be missing slightly for 10-15 mins. Did another...

    EFI Autocal questions?

    Number 2: In order to get tunes through a new tuner you need the current tuner to unlink the autocal. then the new tuner links it to them and you can buy tune. Then just flash the new tunes on the truck. So no the trucks ECM isn’t locked but the autocal is. You can only have tunes from one...

    Factory filter housing is deleted. Fass pressure at 8psi. So the truck runs smooth and no haze or smoke with MAF reading below 38-40. But with the MAF reading 38-40 it reads low at WOT 350-375. Any ideas why it would reads low at wot? New air filter dry air filter (not oiled) new MAF SENSOR...

    Sorry for the delay The last couple months I have been trying to figure this out still. A couple thing I have done. Send that injector back to s&s again they tested it again and it test good but they put a new nozzle on and sent it out. I have switched tuner because figured the MAF reading 55g/s...

    In the process of doing compression test. Can’t get #8 glow plug to even budge. Afraid it’s going to break. I know you’re supposed to remove all 8 when doing a test but Can I still test all other cylinders with that glow plug in?

    LLY rough idle

    Have fass 150. And Ppe race plug. I was playing around with my cts and looking at the PIDS and my MAF sensor is reading 60g/s at idle. My understanding is 40g/s. Could that potentially be causing my problem?

    Replaced #2 injector plug and ice picked the rest of them

    LLY rough idle

    Yeah I have a feeling that there might be something up with that injector. I put an email into them again and see what they have to say. Thank you for the input

    No v2 or tech 2. Have a autocal though. No code show up on my cts2 but will see if code should up in autocal

    LLY rough idle

    All cylinder read read + or - .5 except #8 which is between 2.5 to 3.5. I can get actual rates tomorrow.m Only way I can get them to read in park is if I hold the brake pedal down really hard

    No #2 balance rate is great. Reads Around 0.5. Thanks for your help
