Thread: INFO: 3 bar MAPs on Stock LNF base file

    if you were saying that and i miss read it im sorry
    lol.. I think you may have misunderstood what I'm saying. All I was saying is that (specifically speaking for the lnf. Not an lsj gms2 which is clearly a different story) if you just install the 3bar map sensors, harnesses and then copy ONLY the 3bar map sensor data into a completely stock file, there will be no power gains what so ever. All dals, wgdc, torque limiters, timing, cam tables EVERYTHING is stock, so there is no way any power can be had by just installing 3bar maps and copying sensor data over. Actually custom tuning on top of the 3bar maps as compared to the 2.5bar is obviously a completely different story, but that wasn't where I was going with what I had said earlier.

    I just purchased the GMPP LNF Turbo Upgrade from CED. I would like to tweak my tune after its installed with HP Tuners. Is this possible? I thought I read somewhere that it is harder to tune after GM re-flashes my computer. Does anyone have first hand experience with this?

    Yes it's possible. The GMPP tune has more limiting factors in tables we don't have access to so it is recommended to use a stock file to modify and just add the 3bar map sensor info. In my opinion I would see if you could get a refund and just buy the plug and play harnesses. You'd save a lot of money.

    Thank you both for your information. I talked to Tom at CED. I have decided to send back the GM LNF Turbo Upgrade but keep the 3 bar sensors and the plug n play harness (Tom worked out a great price for me). My next purchases are the GMPP Performance Intake from CED, the next is HP Tuners and the Polished Charge Pipes from DDMWorks !!

    Unless you want them for looks, save your money on the charge pipes. Waste of money if you're running the stock turbo. Not an area of restriction. Same with the GMPP intake. Looks real pretty but not an area of restriction.

    Get HPT, save duckets, enyoy!

    If you have a cobalt just buy a used pipe to replace the hot side over the motor. The pancake tube over the motor is the power maker of the charge pipes.

    The pipes and intake tubes are for looks only. I am still getting the HP Tuner !!

    Then get the GMPP first. It looks like a bazooka lol. I Can't lie. I do kind of like it.

    Hate to bring this back from the dead, but was reading this and am intrigued by it. Now, I have been out of the LNF game since before all the new tables were unlocked (I think I was on the first beta run of 2.23, so forgive me). My brain works a lot like IAB and GMT (IDK if you guys remember me from back in the day), and control is power. So, looking into the future and I know my car will end up with a bigger turbo and probably a built motor, but for now it will not. Future thoughts though, overbuild, undertune... is there anything holding us back from putting in the Bosch 3.5 BAR TMAP sensor? I know not many folks would need this, but it would give us control over 37 psi. Thoughts?

    welcome back kriebs! if your built motor then the only problem will be tune clarity over 30 psi. when tuning for 40 you might have to rescale the axis to only allow idle and enough wot load to control 15-40 psi accurately. big trade off over 35psi

    Would be built and not on the stock turbo, don't worry, I am not an idiot like 3/4 of the people that come here thinking we can put a rocket booster on the car and fly to the moon.

    Hello again! I guess I hadn't thought of the resolution of all the tables. I think the middle of the scale might not hurt, but let's be honest, I won't be running anything up to 40 lbs, but I think 30-32 lbs on certain turbos might happen. We'll see when the time comes. That said, I was thinking purely in theory at the moment, because God knows this KO4 won't spin that high and my wallet can't afford to fix that problem just yet.

    Just making sure the polite indirect way. The k04 will hit 30+ if you want it to.

    Anyone have the install directions for the 3 BAR MAP sensors? I seem to not find it anymore, I want the splice and solder instructions (what wire goes where).
