  1. downloaded it again and works.
  2. The software wont install on win 10, tried compatibility mode in win 7 &8.
  3. The LC1 was warmed up before cranking the engine and yes the fuel was lean. Changed the master fuel from 7 to 17 and it fires up and idles and stays that way, a tad too rich but the problem is sorted. Thanks Jason and Vern, without your help I'd be pulling my hair out over the simplest of things.
  4. Set open loop duty cycle to 90% across the row and when firing up sits on 2200rpm then revs slowly drop till it dies. Throttle had no effect.
  5. Done the Map calibration 5 times and stored each time http://i223.photobucket.com/albums/dd81/30det/mapcal.jpg?t=1289351843 Done the TPS calibration 5 times and stored each time. Set to open loop idle and made changes. This hasn't made a difference, If I crank it without throttle it idles rough, If I give it throttle while cranking it revs up to approx 1500rpm them dies. The pcl file with changes made is below
  6. I havent touched the idle loop table as of yet. I have done the TPS and map sensor calibration numerous times, TPS goes from 0% to 100% and the difference between MAP and BAP is 0.3 Kpa. I'll give the calibrations another go and post the pcl file again. Cheers.
  7. I have recently built an RB30DET with the following specs: R33 RB25DET head recently overhauled, std cams, valve springs and injectors 9:1 compForged RB30 bottom endCustom intake plenum (still retains factory idle control) + Q45 throttle body Custom exhaust manifold with GT35R3.5' exhaustGTR manual gearbox Pics say a thousand words http://i223.photobucket.com/albums/dd81/30det/enginebay1.jpg?t=1289299440 It's installed in a 32 GTST using an r33 rb25det auto loom with a Power FC, datalogit, LC1 wideband and Q45 AFM. The engine has been run in and there are no issues with the loom, sensors or engine (yet). It has made 270rwkw @ 12 psi running off the external 42mm Tial wastegate, the only issue with this setup is the irratic idle which the Q45 AFM has been the cause. It has good even compression and the head was recently removed to check valve seats and cylinder bores, all are perfect. I recently purchased the GTS/GTR link, IAT sensor (GM 358-0003) and expansion connector to replace the PowerFC. The install was straight forward and have got it to start but that's where the problem begins. I have configured the pinouts on the G4 to the factory pinouts http://i223.photobucket.com/albums/dd81/30det/R33ECUPinout.jpg?t=1289295611 but turned off Pin 29/ Analog Input -AN Volt 6 as I'm not using the std oxy sensor. The LC1 is connected to analog Inputs AN Volt 2 and IAT sensor to AN Temp 3 on the expansion connector, these appear to be operating as normal. I followed the step by step guide in the installation manual and didn't have any issues The base IGN and Fuel tables were altered to suit my engine. At the end of the installation manual I found something that doesn't make sense: 'TPS Idle Switch Powered From +5V. This is NOT an issue on manual transmission models. Some automatic transmission models require the TPS switch to be powered from 12V. This can be achieved by removing the wire from pin 57 (Idle Switch Power) and joining it to the wire from pin 59 (ECU Power).' On the RB25 Pin 57 is Exhaust Temperature sensor signal, Pin 48 is Throttle sensor power. As the loom was originally auto and the extra wiring + plug at the TPS is still there should i remove Pin 48 and connect to Pin 59 ECU power? I haven't done this yet. The issue I'm having is when the engine starts it struggles to maintain idle speed (tried 750 to 1200rpm) any throttle and the engine gasps for air then dies most of the time, it idles between 400-600 rpm and sounds bad. There are no fault codes, ECCS sync, trig 1 & 2 are fine and Trig errors are 0. I have physically checked that all injectors are squirting fuel, have spark at all 6 plugs, checked timing with timing gun. I have plugged in the PowerFC and the motor runs as if there was nothing wrong. I have warmed up the engine with the PowerFC then tried the link G4 and still have the same problem. I have tried using the Base map supplied with the Link ECU and had no luck. At this point I pressure tested the intake for vacuum leaks, tried using different vacuum line from the plenum directly to the inbuilt 2.5 bar Map sensor but no leaks. I tried 390,400 and 420 deg Injector timing without luck. I found the installation manual to be vague and know I've missed something in setting up the ECU right. Attatched is my pcl map and a 20 sec log. I hope this is enough information and would appreciate it if someone could tell me where I've gone wrong. Thanks. Brian. RB30DET.370cc.pcl running.shite.llg
  8. What is the ideal size of vacuum hose for the built in 2.5 bar map sensor in a GTS G4 link?
  9. There are 2 wires on the expansion connector that I cant seem to find in PCLink. -Temp 4 -orange wire -Volt 8 -White wire I assume these are analogue channels just like Volt 2 and temp 3 but cannot seem them in PCLink. Any ideas? Brian.
  10. I have a GM 358-0003 IAT and when setting up the IAT through Analog inputs - AN Temp 3 on the expansion connector there is a list of sensors: -Std Bosch NTC -Bosch 0 280 130 017 -Hella 6PT 009 109 041 -Delphi AC -KTY83 -Cal Table 1 -Cal Table 2 -Cal table 3 Which one do I choose? Cheers. Brian.
  11. I have downloaded the latest version of PCLink and cannot find a base map for an R33 RB25DET, the only RB ones listed are R34 and RB20 base maps. If anyone has it can they put it on here for download? Brian.
