  5. Aem 30-0300 WB problem connect to MonsoonG4+ S15

    in G4+

    Posted

    I've problem with connect 30-0300 Aem WB to the G4+ monsoon via CanBus. This AEM gauge use a DT4 pin (+12v,GRD,CANH,CANL) for the road tune purpose. The monsoon can't connect to AEM gauge at all, However this same aem gauge can connect and display Lambda in PClink with G4X Evo3 plugin with the same CanBus configuration.
    120ohm terminal resistor wired between CANH & CANL near to the AEM gauge.

  6. Close loop idle control with poor vacuum

    in G4+

    Posted

    I'm using 3 wires Toyota ISC valve into engine with high cam fitted. when engine idle at 900rpm, MAP read vacuum about 80kpa. The ISC seem only working in between 50%-75%, out of this rpm range the engine speed will no changes, i'm believe due to poor vacuum because of high cam overlapping too much.

    It is better to use AlphaN tuning for more better idle control? Possible to have dual target idle RPM for G4+ with retain the close loop idle control? The engine still can idle fine, but when AC switch on it will pull down engine RPM too much from target idle RPM , and then the idle ignition control will add more ignition timing.

    I've a Links Thunder and use the diagram hold power with low side switching, but the main relay + didn't output Low signal to activate the Main Relay when the IGN SW on, what could be the problem? Do i need configure the MainRelay+ to output Ground or the Thunder will set it to Ground automatically when IGN SW on, and then set to High when keep alive time finish?

  14. engine misfire when Di3 activated

    in G4x

    The misfire problem gone after swap Di3 to Di7.
    for the Output Ignition 4, when setup the ignition system to direct spark, ignition 1 to 4 will automatic configure for coil 1-4, and the ignition 4 can't assign to other pin. So far the engine running good and no misfire with ignition4 set to ignition coil 4.

    use Direct spark with VW short coil dwell 2.3ms.
    we used timing light by clamp on the coil wire no success, after that we remove the cop and add an old spark plug lead between the coil and spark plug but still not success.

    the engine can start and idle properly

  20. Max AUX load not over 2A

    in G4+

    Can i use AUX INJ6 to connect a water methanol solenoid with resistance 8.7ohm, which will draw approximately 14v/8.7 = 1.61A. 
    Follow to Links that shown AUX output max load is 2A.
    the Aux output and Aux Inj output have same max load?

    The engine can start now by setting trigger offset to 279 which copy from the Audi TT starting map, which use exactly same timing style 60-2.
    But don't why timing light can't pickup the signal, can't calibrate the timing offset, the timing light definitely working which tested on other car.
    The timing light just blink randomly which irregular interval.
