Sorry to raise this from the dead It's been nearly exactly a year since I last asked some questions. The engine is now together and has been run in as standard. I am now actually starting to wire in the computer and get the setup together. I am having a bit of trouble on a couple of things and don't seem to be able to get a straight answer. This is how I see it but I'd appreciate your thoughts. Engine: Nissan E15et 1.5 Sohc Turbo upgraded to GT3076R ECU: Link G3 Igntion Mode: Wasted Spark using 2 v6 commodore dual post coils using 2 Ign outputs - Link 2 channel ignitor Injection Mode: Group in 2 batches seperated over the 2 inj outputs Ign 3 - Ign 4 - Aux 1 - Idle speed solenoid nissan Aux 2 - Tachometer Aux 3 - Aux 4 - Used as DI Aux 5 - Electronic Boost Control - link supplied solenoid Aux 6 - Engine Coolant Fan Relay Aux 7 - Intercooler Fan Relay Aux 8 - Fuel Pump Relay DI - Clutch switch - Launch control/Flatshift Volt 1 - Volt 2 - Temp 1 - Air intake sensor - bosch unit purchased with ecu, o-ring type Temp 2 - Engine coolant temp - Standard nissan sensor Load Input - TPS - Sensor?? Trig 1 - Nissan CAS Trig 2 - Nissan CAS The questions I have are: 1. Will the commodore coils be appropriate for this type of use, I can get much newer ones than say a mitsi twin post or a subi one that the posts face opposing directions and won't look tidy. 2. What are your recommendations on the ecu it is a LEM g3 I bought in 07 (these projects take longer than expected) if I upgrade the firmware what else do I get? What approximate cost am I looking at? 3. Can I still download a version of PC Link that will work 4. I know that the ECU can handle low or high impedance I had heard talk of low impedance injectors run through balast resistors being hard to tune. I have calculated I'd be looking for 550cc injectors which I should be able to get as high impedance. What is best? 5. O2 sensors I have the one fitted to the car that I assume is narrow band. If I'm getting this tuned professionally is there any point in wiring this up. Is there any advantage to going to a wideband and if so what? 6. The stock nissan E15et sensor is a simple on off idle type TPS. What would you recommend to use for this application. Something that bolts up would be nice. What I'm looking for is what will work and what is easiest to tune as I don't want to tow it to a dyno for someone to look under the bonnet and say it won't work. I just want to make sure I understand and am making all the right decisions. Appreciate your assistance. Cheers, Dan P.S. Sorry for the novel

I'm finally getting to the end of my little project and going to start wiring my computer over the next couple of months. It's a link computer g3. Turns out it's been so long since I bought it there's a new model. I'll be running group fire injection in 2 sets of 2 and wasted spark. The sensing gear for our standard engines being in the dizzy. My question here is in regards to triggers it refers to using 2 sensors a cam and a crank angle sensor. I thought the engine used hall effect sensors but only as a cam angle sensor. Do I need to set up some another form of optic or magnetic sensor on the crank or will the standard sensor do the job..??
