Remy van den Hoek Posted May 6, 2016 Report Share Posted May 6, 2016 Hi, I'm having a strange problem with my link g1 v10 ecu.To get the car running, I perform a reload, the car starts but runs terrible (way to rich).First step, is that I reduce the master fuel setting from 130 to 65, when I go lower the engine starts to stutter when I rev it. wide band AFR is now around 10.Then I lower the values in the first row to around 65 till 75, AFR is now around 12/13.I can now drive the car around the parking lot and its running smooth and idles fine, so I save the settings to my computer and to the ECU.Now the problem, It won`t start again (cold or hot) until I perform the exact same steps from above (perform a reload etc.), while all the adjusted settings I made earlier are there.The car is a VW Corrado 1.8L 8V 4cyl, t28 turbo, 500cc genesis injectors.Running group injection and a distributor for spark.Any ideas/suggestions in what I`m doing wrong?Many thanks Remy.LINK MEMORY DATAConfigurationRow Steps = TPS+MAP Priority = CylAirCon Request = Low-High Aspiration = TurboDwell Mode = 4ms Engine Configuration = GeneralInj Mode = Group MAP Sensor = ExternalNumber of Cylinders = 4cyls Temp Sensor = NTCLimitsAdvance Limit = 33° MAP Limit = 230kPaMAP Limit = Off RPM limit = 6800rpmLambdaShift RPM = 5000rpm Closed loop Lambda = Off Lambda Targets TableTarget Area Idle Cruise Rows 4 & 5 Rows 6 & 7 Rows 8 & 9 Rows 10 84 78 82 83 85 87 UtilitiesRpm Lockout = 500rpm Overrun Vacuum = 24kPaTPS High = 100 Temperature Switch = 94°CUtilities - Drive ADrive A Trigger = RPM Drive A Sense = OFF->ONUtilities - Drive BDrive A Sw Point = 4000rpm Drive B Trigger = RPMDrive B Sense = OFF->ON Drive B Sw Point = 4000rpmUtilities - Launch ControlLaunch Ctrl = Off Launch RPM = 3000rpmUtilities - Water SprayWater Spray Trigger = %FF Spray Sw Point = 70.2%FFIdle Speed ControlWater Spray %DC = 50% AirC Step = 10Fan Step = 5 ISC Type = SolenoidIdle Cold = 70% Idle Hot = 60%Idle RPM = 900rpm Stepper Motor Direction = NormalFuelMaster = 65 Fuel Cut = OffFuel - AuxiliaryInjector Timing = -1 Clamp = 75kPaAirC Enrich = 0 Cold Start = 36Crank Decay = 20 Crank Enrich = 60Hot Restart = 0 Inlet Air = 10Prime Temp. = 20.0°C Volts Correction = 15Fuel - AccelAccel Decay = 8 Enrichment Mode = MAPWakeUp Pulse = 4 WakeUp Width = 210IgnitionIgnition Type = Distributor Ignition Coils = Single CoilsKnock ControlStatic Ignition = 6 Knock Base Target = 60Knock Control = On Knock RPM Start = 2000Boost ControlKnock RPM corr. = 20 Boost Hold = 80% Boost TableEngine Speed (rpm) 250 750 1250 1750 2250 2750 3250 3750 4250 4750 5250 5750 6250 6750 7250 7750 8250 8750 9250 9750 MAP (kPa) 200 200 200 200 200 200 200 200 200 200 210 210 210 210 210 210 210 210 210 210 TPS Proportional = Off Wastegate Base = 35Wastegate RPM = 3200 Wastegate Sens. = 6Boost Control - AntilagAntilag = Off Antilag Mode = Mode 1Ign Retard = 20°Fuel Table Fuel TableEngine Speed (rpm) 250 750 1250 1750 2250 2750 3250 3750 4250 4750 5250 5750 6250 6750 7250 7750 8250 8750 9250 9750 TPS/MAP15 65 65 65 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 78 45 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 75 108 108 108 108 108 108 108 108 108 108 108 108 108 108 108 108 108 108 108 108 105 128 128 128 128 128 128 128 128 128 128 128 128 128 128 128 128 128 128 128 128 135 132 132 132 132 132 132 132 132 132 132 132 132 132 132 132 132 132 132 132 132 165 136 136 136 136 136 136 136 136 136 136 136 136 136 136 136 136 136 136 136 136 195 140 140 140 140 140 140 140 140 140 140 140 140 140 140 140 140 140 140 140 140 225 144 144 144 144 144 144 144 144 144 144 144 144 144 144 144 144 144 144 144 144 255 148 148 148 148 148 148 148 148 148 148 148 148 148 148 148 148 148 148 148 148 285 152 152 152 152 152 152 152 152 152 152 152 152 152 152 152 152 152 152 152 152 Ignition Table Ignition TableEngine Speed (rpm) 250 750 1250 1750 2250 2750 3250 3750 4250 4750 5250 5750 6250 6750 7250 7750 8250 8750 9250 9750 TPS/MAP15 6 11 16 21 26 31 33 33 33 33 33 33 33 33 33 33 33 33 33 33 45 6 11 16 21 26 31 32 32 32 32 32 32 32 32 32 32 32 32 32 32 75 6 11 16 21 26 31 31 31 31 31 31 31 31 31 31 31 31 31 31 31 105 6 11 16 21 22 24 26 28 28 28 28 28 28 28 28 28 28 28 28 28 135 6 11 16 21 22 24 26 28 28 28 28 28 28 28 28 28 28 28 28 28 165 6 11 16 18 18 18 20 21 28 28 21 22 23 23 23 23 23 23 23 23 195 6 11 16 18 18 18 19 20 20 20 20 21 22 22 22 22 22 22 22 22 225 6 11 16 18 18 18 18 18 19 19 19 20 21 21 21 21 21 21 21 21 255 6 11 16 18 18 18 18 18 19 19 19 20 21 21 21 21 21 21 21 21 285 6 11 16 18 18 18 18 18 19 19 19 20 20 20 20 20 20 20 20 20 custom 05-05-16.pcl Quote Link to comment Share on other sites More sharing options...
Remy van den Hoek Posted May 8, 2016 Author Report Share Posted May 8, 2016 This morning I tried setting Crank enrichment to the smallest number possible (30) which should give the most fuel while cranking. Still wouldn't start.After this I tried setting the master fuel back to 115. Now she started but ran way to rich. Only after setting it back to 65 the engine started to ran normal again.Should I set the master at about 80 and just lower the entire table a lot?

neil brown Posted May 8, 2016 Report Share Posted May 8, 2016 lower the entire table Quote Link to comment Share on other sites More sharing options...
Remy van den Hoek Posted May 9, 2016 Author Report Share Posted May 9, 2016 Ok thanks, I'll do that.Is it beneficial to set the master fuel as low as possible or should I just leave it at 110 and lower the table from there?To make sure adjustments can be made, I assume crank enrichment needs to be set somewhere in the middle, then set master fuel to a value on which the engine starts, followed by lowering the table to get a acceptable AFR. Is this a good approach? Quote Link to comment Share on other sites More sharing options...
Simon Posted May 10, 2016 Report Share Posted May 10, 2016 (edited) You want the master to sit where the table numbers are in the mid range of the adjustment so around the 100 mark at mid power.Get the main tune done fully and then go in and adjust crank enrichment.

To get the correct AFR I had to set master fuel to 130. The car would barely start when cold, but once hot I wasn't able to get it running again. My master fuel is now at 150, crank enrichment is 30 and hot restart is at 10. With these settings it will start after 3 or 4 times cranking the engine for a few seconds (hot and cold). The first fuel row goes from 30 till 45 and gives me around 14.5 AFR, to help AFR in idle I set the first ignition cells to around 16. The engine revs perfect and drives smooth around the parking (not allowed on road yet). The MAP sensor (GM 3 bar) reads 103 kpa when the engine is off and 65 kpa in idle. I set clamp to 65.I find it strange that I have to set the master this high just to get is started, and I still have the feeling that I`m missing something. The engine is a 1.8L 8V 4cyl, running a T28 turbo, 500cc genesis injectors @ 3.5 bar fuel pressure (stock pump feeds a sump with a bosch 044). Running group injection and a distributor and single for spark.Thanks for still supporting such a old product, many companies could take a example from that!
