Hi Ashley, Well i decided to plug in my factory ecu and boost solenoid to see if the misfiring stopped but guess what? It still misfired @ 1.1 to 1.2 bar! I took out the plugs and they were a bit worn. Like 1mm of metal was missing from the centre electrodes and had welded it self onto the earth electrode. Put some new plugs in and gapped them to .8 mm but the misfire is still there. I did a comp test and it was 130 psi in all cylinders. Tested my coil and its within specs. Just the primary winding is over by.5 ohms. HT Leads are within specs as well. I guess the only thing i can do now is bite the bullet and change my coil and HT leads because its very hard to diagnose without a dyno. Is there anything else you can suggest that i should check/ change. Really appreciate your help.

Thanks for the info bro. Much appreciated. Im slowly turning up the boost and its currently on 0.9 bar. I have adjusted the the fuel map for idle and its now at 14.7. Light throttle its around 13 and full boost its around 11.2. I am using an Innovate LM-1 for the air fuel ratios. From experience, are these ratios fine and can it do any damage. At full power, what ratios should i watch out for? I think i figured out what the seemed to be detonation. It was the rpm cut. I have learnt how to adjust the rpm cut properly and its nots cutting in at around 7200 as before. Regarding the MAP cut, can i change this to 240 kpa or should i just leave it at 230? Thanks.

Hi, Just wanted to know if someone could provide some tuning help for my v3 sti with a link g3 /adaptor? I am located overseas and i got the link ecu tuned in nz but i think it was done on 98 octane. Our fuel here is around 95 with octane boost. I gave the IIguy a list of my mods and he tuned it accordingly. I think he has a v3 sti with similar mods. The problem im having is that when i run 1-1.2 bar of boost, the engine starts to lose power and seems to be detonating. There's like popping noises through the exhaust. I currently set the duty cycle on the boost solenoid map to 0 and its on spring pressure now which is around 0.6-0.7 bar and it doesnt detonate or miss like before. I will gradually increase the numbers and see where it starts to detonate. My air fuel ratio at idle is 13.1 (operating temp) and 11.2 at full power. Is this ok or is it too rich? Also, what would af ratios be when the engine starts to detonate and what will the lambda reading be? It would be much appreciated if you guys could help me out here as there are no dynos here and i have to tune the car myself on the road. My mods are: 3" exh (no cat), FMIC, Pod, BOV, LINK G3, Will spark plug gaps cause detonation, i havent adjusted spark plug gaps and im not too sure what they are currently. The vehicle was running perfectly with my factory ecu on 1.2 bar standard so i think the fuel isnt too bad otherwise it wouldnt reach 1.2 bar. What do you guys think? I have done all the mods to the car myself but i have very little experience with tuning aftermarket ecu's. Your help will truly be appreciated. Thanks guys.

nah its cool...i figured it out...thanks anyway bro

Thanks Ross...i have the bosch sensor...the thread size is 17mm

Hi guys, About to install the G3 with adaptor to my V3 STI. Just wanted to know the colour codes for the signal and ground wires on the AFM connector which i need to use to wire in the Air temp sensor? Also have to mount the sensor to the intercooler piping. Can someone tell me what size drill and tap i should use? Im not very good with taps so i dont wanna stuff the piping up. Thanks.
