you might try a pull down resistor. you do this by attaching one end of the resistor to the trigger wire and the other side of the resistor directly to ground. start with 1000 ohms. a lower the value of the resistor will "leak" more to ground and could keep the fan on all the time. some...

i thought about this, but the fact that you put a traditional relay in and it worked indicates the output is going low. assuming you had 12v on the other side of the relay.

things to check if it ran properly once upon a time bad TPS bad MAP sensor or leaking line feeding it faulty fuel pressure regulator, or a leak in the line assuming its manifold pressure referenced. loose or bad plug wire(s) could be other things but these would be the most obvious usually...

why would it need a dyno tune? is this a new motor that was never properly tuned to begin with? or did it used to run properly?

first nobody makes a relay worth a shit anymore. just another reason to go solid state but thats a topic for a different discussion. OP mentioned there is a sender in the water pump, I will bet that is for a gauge and not the ECU temp sender which is typically in the head on LS motors. The ECU...

get the Hella relays with 1/4" terminals. the same relays with the smaller terminals have a habit of melting the terminals, even when well below the rated load.

i have a mefi 4 with harness. PM if interested.

fuel pressure is solid......lmao........with the car sitting static and a full tank. now run it down to half a tank, first pass through the whopps.....you have a stew of air and fuel going through your system.

i would vote NO WAY on carbs. but i get it to a certain extent.....they are easier to setup. but the tunability isnt there. wouldnt run any better than your 4 knob setup. the tough part about efi on an ACVW is there is SOME bolt on parts for doing this. Specifically, ditch the distributor and...

yep as stated that system is a JOKE. sure having fuel and timing correct will help the turbo "do its thing". you will NEVER get there with that 4 knob system. not trying to talk you out of changing motors. but going from air cooled to water cooled is no easy task. hence the reason i suggest...

before changing motors, DEFINITELY get rid of the old CB system. total DINOSAUR with no real tuneability. as for building boost....the ECU cant help much with that. its entirely mechanical. so either your turbo is an ancient piece to, or its worn out, or you have leaks in your system or the...

classic sign of overcharging. and this is the problem with these dry cell AGM type batteries, they were never designed to be used with high output automotive charging systems. sure there are all these claims from battery manufacturers about these new small, lightweight wiz-bang batteries and...

colder will make the problem worse. this is assuming there isn't an underlying problem, overly rich mixture, weak ignition system, excessive blow by (worn out engine).....stuff like that and the plugs fouling are just a symptom of a greater issue.

thats a very good price, assuming its not the cheap TXL wire covered in raychem. If is tefzel m22759, dr25, and OEM connectors buy as many as you can. i build harnesses for Motec systems, try and stay away from Holley as much as possible.

yes. but not the chineesium knock off you linked to. get the genuine Radlock ones......work very well.
