    Ok so lets confirm all of these are set and give it another go as lots of people have full open loop working on the FG.

    P1227 MIL Lamp

    auF1328 P1227 Fault Filter set it to 255

    auF1193 P1227 Fault Filter set it to 255

     

    Over/Under boost

    auF1898 Open Loop duty cycle for underboost set it to something like 40%

    auF1679 Underboost Threshold - set entire table to something like 40-100

    auF0296 Overboost required for open loop - set this to something like -40 to -100

     

    PID Gain tables

    auF0286 Boost Integral Gain - set entire table to 0

    auF0287 Boost Proportional Gain - set entire table to 0

    Zero all of these gains

    auF16555, auF16567, auF16552, auF16519, auF16453, auF0289, auF0288

     

    For good measure set auF16551 TPS vs RPM scaler to 1.0 everywhere other than idle.

    ok iv done all that but there a few tables I don't have auf1193, auf1679, auf16551

    Set your overboost (auF0296) to -100 and your underboost to 100. You have a positive number in overboost currently, which means it is stuck in no mans land of simultaneously having over and underboost.

    I tired it both ways after our convo yesterday, one way no duty cycle the other way under boost kicks in and 100% duty cycle

    As you should. This can be done quite quickly by logging map, wg duty cycle and boost error. You can also wing it by watching your boost gauge if you're feeling deadly.

    What turbo are you running?

    im logging all that and on a dyno, it's a gtw3684r external gate

    Haha I was just dropping the lad at school but had already written this 5 minutes ago.

     

    Running in open loop is a bad idea if you want accurate boost control as a cold night will add a few psi over a warm day. If you are at a boost level on 98 octane that wont allow more timing then you will have issues with detonation.

     

    From what you are saying it seems that you should run the factory boost control as it was intended with a mixture of open loop and closed loop.

     

     

    I would like to dial in open loop before I even consider closed

    It won't work like this. It will use the number in auF3184. So if you set this table to 100 then it should never trigger an underboost scenario. Normally it would trigger 100% duty cycle only until it is out of the underboost condition. The fact you have zero'd all your PID gains is why you are having issues.

    If you leave closed loop boost control enabled, you will have better results and you won't have to mess around with these tables. Is there any reason you don't want to run it?

    if I set that table to 100 there is no wgdc at all, did you look at my file?

  6. I will give it a try, but there are a lot of tables that say they will do things but must get over ridden. Eg max wgdc I set that to say 70% for some safety but it just dose nothing. Answer to Roland I just don’t like the fact that if at any time ( if something go’s wrong) the ecu see’s even 1 psi of under boost it will give 100% dc, this is a large turbo and will pump out 35 plus psi.

  7. ok iv been tuning with hp tuners and im finding it hard cross over and to now what tables are the same in pcmtec. is there a way I can tell if the tables are the same because there are a lot of tables named different things and some I can't fined. In hp there is a ecm number for each table the same as efi live, is there any where in pcmtec that there is this table number.?
