Re: Odd heater behaviour

Just checking... but you have checked that when the cabin control is set to full heat the heater tap is also wide open (spindle fully up) ? If the core was clogged I wouldn't expect the heater to work fine for a while and then suddenly stop working. None the less, I would suggest reverse flushing in...

Re: Check Engine Light, goes off @ 4000 ish rpms

No worries... I love a good mystery :) Was thinking that maybe the Ne signal from the distributor was weak until the engine reached that 4100rpm tripping point. If it was and if you have the VAST ignition system, then the ignition would stay at base advance (10 DBTDC) until the signal got strong eno...

Re: Check Engine Light, goes off @ 4000 ish rpms

My bad... was thinking the light went off at high rpm but wrote that it came on... DOH !!! You can make the checks and tests that I suggested. And if the light is ON when the engine is idling you can get someone to watch the CEL while you manipulate the wiring near the distributor. When the car is r...

Re: Check Engine Light, goes off @ 4000 ish rpms

1. Does the CEL light come on in every gear at around the same rpm ? Like if you go from a standing start and rev to 5000rpm before changing... does it on come on in every gear or only when you get to 3rd or 4th ? 2. If you raise the rpm to 5000 in neutral while stationary, does the CEL come on ? Th...

Re: cannot get Link AtomX tach output to work with factory cluster

I'm interested to see how this works out. There are multiple writeups and videos showing how to modify and fit digital clusters into various old Toyotas, but not one of them identifies the required tacho input waveform. In fact most writeups kind of fizzle out due to problems in getting the dash to ...

Re: Headache and a Half -starting/rev cut

I guess that a 16/20 4AGE is a 16V head on a 20V bottom end. In which case you will have obtained some increase in compression but otherwise the fuel and air requirements will not have changed much from the factory 16V setup. Thus if the OEM injectors were 210cc/min low-res then they would be your b...

Good progress... one problem at a time is the way to go :) AE86 does not prime the pump when you turn the key ON. The pump does not turn ON until you turn the key to the crank position. If the engine is slow to start when cold you should check that your cold start injector is working. If you have be...

Re: Odd heater behaviour

I was meaning the heater hoses. A collapsed radiator hose would not make the heater run cold... more likely just the opposite. Some basic checks would be if you stop the car (but keep the engine running) after the heater starts blowing cold, does it return to blowing hot air without you touching or ...

Yeah... but I was actually referring to the skinny wires that take the pickup signals out of the distributor to the igniter or ECU.

Hey brother... good to see you are still beating on an AE86 :D Sounds like you have an electrical problem going on.

Re: Shock Dyno Data Anyone?

OEM replacement in terms of physical size, but with up-rated valving to handle modest
lowering and "sporting" spring rates. I believe that OST used 112's and found that he had
to be inventive in keeping 4.4 (?) kg/mm springs captive.

Only logical explanation is that there is no longer any hot water reaching the heater core. https://i.pinimg.com/originals/a7/47/6b/a7476b7f6f94e3bc89b2684913d306e1.jpg The outlet from the heater connects to the suction side of the water pump so unlikely as it may be, perhaps you have a hose that ge...

Re: cannot get Link AtomX tach output to work with factory cluster

Just to be clear, the simple solution outlined above won't work with a dedicated tacho output that produces a 5 or 12V square wave. If that is how your tacho output works you will need to see if you can program a spare aux output to behave as a tacho and pulling the 12V supply to ground at the engin...

Re: cannot get Link AtomX tach output to work with factory cluster

If your ECU has a tacho output that switches 12V to ground you can produce a voltage spike suitable for driving an OEM AE86 ANALOG tacho with a small relay coil. That's easy :) What is difficult is knowing what kind of input signal (voltage/frequency) your DIGITAL dash requires. If the digital dash ...

Re: opinions on my efi journy

Have you tried locking the timing in the ECU to see if that calms things down ? You presently have two items that are capable of changing the timing with rpm... the MSD (programmable timing curve) and the ECU (ignition map). If both are active then your timing will jump around. Cheers... jondee86
