we all have or experienced the faulty CPS wiring problem but my question is pretty simple. Is it the clip that causes the connection problem or is it more internal like inside the actual CPS? becuase sometimes when my car dies on the road i simply pop the hood, undo the clip, clip it back in...

alright so i already received excellent advice as to how to tune my car, but one thing that i'm not certain with is tuning with the Vf signal. I know it'll range from 0-5v, and that 0 volts means it is running rich and 5 volts means that it is running lean....at idle and when my car is at...

one day i set my Fuel pressure and my S-AFC pretty good where i was getting consistent 10.5-11.5 A/f ratio numbers. But today with the exact same values plugged in i was running LEAN...like 12.5-13.5 Why does it ALWAYS do this to me?? i used the same gear to test it out, it is about 10...

so i tried starting my car just right now after a couple months of winter. All i did to it over the winter was an HID installation so nothing drastic. Right before i stored it i did my fuel system swap lexus/580cc/walbro/FPR/Apex-i S-AFC and i put MAYBE 100 km on it. Here's the thing....i...

i still am having trouble tuning my car....i have the basic ct-26/lexus/580cc/walbro/apex-i. I cannot no matter what i do get my AFRs at idle to stay put. It always fluctuates from like 14.4-16.0. It never stays still. Is this becasue it's a piggyback system and not a standalone??

i'll do a simple rundown of my mods that matter..... -lexus AFM (no adjustable screw) -580 cc injectors -AFPR -walbro -PLX wideband -J tube removed -K&N -2.5" hardpipes -FMIC -blitz BOV -Apexi S-afc so anyway i *think* i have my base pressure at 20-25 PSI with the line ON. I have...

so here's my car: FMIC 2.5" hardpipes lexus AFM 580 cc PTE injectors afpr walbro 3" tanabe 3" BIC DDP 3" test pipe SAFC and i'm hitting 15 PSI WITHOUT a boost controller of any sort. How can i lower the boost?? i know the CT isn't all that great with that much pressure.

So let me get this straight with your help. The ECU controls all fuel maps under 75% throttle thus meaning that any changes to the SAFC at LOW THROTTLE settings are basically useless?? and on the SAFC i should have the low throttle at 74% and high throttle at 75 %?? so if that makes sense...

i'm running no cats, DDP and i think a leaky turbo. So yea, my car smells bad under boost. You??

i have my wideband hooked up and after trying to tune it without any sort of datalogging is difficult. So, i have a PLX m500 and i want to hook it up so that i can datalog my highway pulls. I have 6 wires. 2 for speed and 4 for analog. Which pinouts do i hook these up to?? for sure 1 speed...

before i go ahead and install my gas tank back in, i'm kind of skeptical about using the butt-connectors they provided. Is there any reason why i SHOULDN'T use solder along with some heat shrink?? will the gasoline in time dissolve the solder???

i installed PTE injectors, AFPR, lexus AFM and since then my car has been sounding pretty bad at idle. It seems to only happen when the car is at full operating temp. The noise is VERY audible from inside the cabin but outside the car you can't hear it at all. The closest thing i can think...

so i installed 580cc injectors, AFPR, lexus AFM and on some occasions i hear a "ticK" sound comming from the top end of the motor. I'm assuming the injectors, but do they really make that much noise??

what is the blue wire, yellow wire, and white wire for?? those are the only hookups not installed for my S-afc. The PDF on apex-i says that the purple wire is for knock, however i don't have a purple wire. IS that the blue wire they speak of?? Also how do i RESET all the settings on the...

went to finish my install today and nothing. So i opened up the actual casing and the plug connector inside the S-AFC was actually half off so of course i was happy and delighted that i found the problem. But when i put it all back together and turned the key to "ON" i still got nothing...

installing my Apex-i right now, and i want to know the best way to splice my wires into my ECU harness. I can think of a couple of ways to do it but 1 method wouldn't be all that secure, and the other would require me to cut the wire, solder on a new piece of wire WITH the proper S-AFC wire and...

well being very stubborn and very impatient, i went ahead and installed my 580 PTE injectors, aeromotive FPR, lexus AFM and soon to install my S-AFC and wideband. HOWEVER, i left myself a nice full tank of 92 octane fuel. I didn't want to wait to install my goodies so i decided to rip it apart...

i'm going to install my AFPR tomorrow and i'm wondering how tight i should tighten all the fittings??? is there an actual torque spec?? and tips you guys have for me?? Thanks

NO EBAY because i don't trust the injectors there. I've checked all the major vendors and so far mvpmotorsports has my attention. I've also dealt with mvp before and they are awesome. SO who else should i look into if i want to buy RC 550cc injectors and clips??
