Rolls Posted September 18, 2011 Share Posted September 18, 2011 I was thinking of something. If I built a small circuit consisting of a few LED's ranging from red to yellow to green which will receive the AFM voltage signal as the input and work in such a way that when the volts are low the lights are red and when the volts and air rises the lights will go to yellow and green, could I use this as a clear display for me to monitor when I am getting effects of reversion to determine if its an issue? I don't think it will take long to make and I should have all the parts I need. I can just keep my eye on my power fc hand controller afm voltage and see what happens. Or just monitor the signal with a multimeter lol. Better yet an oscilloscope but I doubt you have one of them lying around. Surely the powerFC software can graph AFM volts vs time though? That would be the easiest way to see.

Surely the powerFC software can graph AFM volts vs time though? That would be the easiest way to see. I has an oscilloscope which I found years ago lol it's been binned though. I might invest in some power fc software. I am fairly certain it can log afm signal against time and rpm. I've got a multimeter but the fluctuation might be too quick I won't see it. With the power fc I can reset the max readings the second I back off the throttle and then check them again. Damn it would be sweet if I could get some power fc data logger on my phone lol. OdbII has it and you can use bluetooth too dammit lol.

Rolls Posted September 18, 2011 Share Posted September 18, 2011 If the consult port still works with a powerFC just use ECU talk and log afm voltage and graph it, very easy to use piece of software.

SargeRX8 Posted September 18, 2011 Author Share Posted September 18, 2011 Sigh, on high boost drive today(first drive after cleaning the AAC valve) the car hit 107 knock on the PFC. Now its misfiring its arse off.

SargeRX8 Posted September 19, 2011 Author Share Posted September 19, 2011 Coil packs failed on me. Stock ones are back in there. Damn yellow jackets, lets hope they can get replaced under warranty. Second set to fail on me I haven't tested if this fixed my stalling or lean popping issue but it seems everything came at once so lets try iron them out.

SargeRX8 Posted September 19, 2011 Author Share Posted September 19, 2011 Spray the stock coils with CRC urethane seal coat Sarge. Ill do this, sounds like a mint idea too. I'm using Nitto tape, good shit but under that heat it does dry up pretty quickly. Damn and i was thinking of yellow jackets after readin some reviews of them., now im stayin clear, ur not the only guy to report their failure.. Don't get me wrong, they work. They work awesome, it just seems that maybe the heat in a modded engine kills them early. Maybe 19psi is too much for them. Could be many reasons but I can tell you the warranty and service behind them(from performance wise) is second to none. Spoke with him today and he offered me a full refund or replacement set. Unfortunately I think I am going to take the refund then invest in a set of spitfires. Looks like the stock piece is holding pretty well so far too. 15psi on the drive home no miss.

GTScotT Posted September 20, 2011 Share Posted September 20, 2011 So the issue seems to have been coilpacks? Would be good to get it out there..

SargeRX8 Posted September 20, 2011 Author Share Posted September 20, 2011 So the issue seems to have been coilpacks? Would be good to get it out there.. I was thinking of getting a set for my SR well no, the coil packs were my latest problem but I'm still having issues with strapping and idle and cruise conditions... I spoke with performance wise and the highest failure rate is only with series 2 coils. Apparently the coils might have an issue with the dwell time of the series 2...

SargeRX8 Posted September 25, 2011 Author Share Posted September 25, 2011 you guys figure this out yet? its not hard. its pretty obvious what is going on here. Not yet, its only when the car is warm it lean pops. Please man if you got any ideas let me know.

Guilt-Toy Posted September 25, 2011 Share Posted September 25, 2011 Not yet, its only when the car is warm it lean pops. Please man if you got any ideas let me know. I have many ideas.... but lets start with this... Warm the car up, make it so its popping on idle... then... go to the petrol station, don't stop the engine and fill the tank with 98 to the brim. Post back results.

Crans Posted September 26, 2011 Share Posted September 26, 2011 Do you have your PCV connected to the Plenum? Make sure that valve is still working If it is still connected do your cam cover breathers still connect to the intake pipe after your AFM?

SargeRX8 Posted September 26, 2011 Author Share Posted September 26, 2011 (edited) Do you have your PCV connected to the Plenum? Make sure that valve is still working If it is still connected do your cam cover breathers still connect to the intake pipe after your AFM? It is still connected and was replaced with a new piece as the old one broke during replacement of the injectors. I had no issues with the car until I measured up a new intake pipe. I did NOT fit a new intake pipe it. Merley measured up a new pipe then put everything back together and its been lean popping and stalling since. Also noticed my fuel cap isn't going pssh anymore and noticed fuel fumes coming from the fuel cap again ffs. Ive got my intake breather hooked up to the exhaust breather(like standard) then fron the exhaust side to a sealed catch can then back to the turbo. Below is a diagram of how shit is facing and what not.

Guilt-Toy Posted September 26, 2011 Share Posted September 26, 2011 just go to the station, fill the car up while its popping. after you put a fuel talk, does the popping go away? also take picture of your intake pipes and post them up please.

Rolls Posted September 27, 2011 Share Posted September 27, 2011 Isn't that dangerous lol. What should or shouldn't happen? As long as you don't spill petrol all over your exhaust I can't see the issue, no more dangerous than normal I'd say, it is just a precaution in the odd event you have arcing in your engine bay and there happens to be close to the lower explosive limit concentration of vapours in the air, basically a 1 in a million chance.
