Another use for this would be to reduce fuel pressure at idle and cruise. I'm running 4bar fuel pressure to get enough fuel up top, but at idle I have difficulty getting a stable idle at lambda 1due to being in the non linear area of the injector. At 3 bar idle it's more stable.

And the issue was, cam and crank sensor polarity. Go figure. http://forums.linkecu.com/index.php?/topic/6301-subaru-ej20-reluctor-wheels/#comment-45251 Having automotive mechanic as my back ground i know you don't need luck if you can read and understand the help file. Not understanding how to use or read the help files means the poor LINK tech's get dumb ass topics like these.

Was hope full this was in the latest release.

Scott's screenshot proves my theory. Quick to blame the product before doing basic checks.

I use image shack to load images. Didn't think it was that hard to do. Would of been quicker then posting in multiple threads. With out a log or screenshot you come across as a wanker.

Read his last post.

Is it normal for the Battery voltage to be displayed a little different from the power supply to the 3 pins into the ECU. Its out by .20 volts. AUX 9/10 and 17-20 match the voltage at the fuse when i checked pin 5 Plug A it was the [email protected] volts

I have a engine fan that is PWM and trying to work out if its possible to configure a virtual output so that when the fan status is on it triggers the idle speed control engine fan step to increase the idle.

Can you attach a copy of your file that way tech support can view your settings or email it to them. Makes it a lot easier and less time consuming.

Looking at the log the trigger 1 error jumps when the rpm spikes. Is it a factory harness? How do you have the sensors mounted and configured? Also can you post a trigger scope image.

I would start by using the latest PC link and firmware.

I would like closed loop for my water to air Inter cooler setup. ATM I have a PWM table setup with IAT and water cooling temp.

My bad those pins are on plug C. Can you post up a wiring diagram of how you wired it up?

When I wired mine it would power up at around 6 volts until the ecu relay triggered power to the ECU. How have you connected ignition switch, main relay +, main relay - ? On plug D.

All works after the update. Thanks Simon

I moved the fuel pressure input over to ANV 9 and still will not show fuel pressure.

Hi Mapper, Is that with both Map referenced and fuel pressure senor referenced fuel system type tho? I might try setting the dead time axis to fuel pressure and fuel system type to fuel pressure senor and see what the difference is.

Thanks Scott, saves me any more headaches working that out. Found out today the dead time data supplied by Motec is battery voltage and fuel pressure. I had it setup as differential fuel pressure. Minimum effective pulse width is also too low causing high valves in the fuel table.

Thanks for your input Rich. Dead times were supplied by Motec and Short pulse width adder valves were worked out for me by the senior engineer at ASNU. Going by the factory running temps the recommended temp range is 78 to 83 deg C. Im running electric water pump so still dialing that in as well. Warm up enrichment is now at 0 when up to operating temp, Charge temp is all water temp bias at 100% until i can at least get this thing to rev. Tested the map sensor against the 100 psi water temp sensor and scale was good. Connected a brake bleed sucker to the Map and is reads negative psi so sensor must be good. One thing i did notice is when it was set to Link 5 Bar at high boost it was 5 psi out compared to the Honeywell 100 psi sensor. When i swapped to SRS 5 Bar it matched the Honeywell sensor. ANV 13 has the function of Fuel pressure from the drop down box. So unsure whats going wrong there. I had i bit more of a look today and noticed differential fuel pressure went all weird when swapping to FP sensor. Im thinking i have the axis of the dead time table wrong I have the Y axis as battery voltage and X axis as Differential fuel pressure. Is this right for modeled fuel or should X axis be Fuel Pressure For some reason i cannot attach log as its saying the log is too big even tho it only run for a few seconds

Im after some advice as to why when switching fuel pressure input from map reference to FP sensor the AFR go RICH. Im using all new sensors, link 5 Bar map and 100 psi Honeywell fuel pressure sensor. I tested the Fuel rail pressure against a external dial gauge and the calibration is fine. Map sensor calibrated ok in the software. Map sensor is using a short Dash 4 hose to intake manifold that sits above the intake manifold. Monday ill make up a test adapter for the map sensor. Fuel table in modeled mode is in the high 90's on a sr20 which seems high at idle. In the log files for some reason fuel pressure does not show even tho AN13 shows fuel pressure. Not sure if this is the reason for my troubles. Or are am i missing something simple?

You could try dropping the signal voltage from the coil back under 5v and using a analog voltage input.

Can you upload your pcl file to have a look at?

Under trigger limits in run times values trigger status NO should change to YES during cranking. Are both doing that?
