well as the title says i have a hf 89 honda crx have wire conversion kit for the distributor only i am useing the same ecu have other things worked out for vtec not worryed about that but i put a new coil in it thought i had a week coil but seems to still not be fireing. the first crank after a few hours will give me one or two sparks and then nothing at all. if anyone has any sugestions on what could be going on i would appresate it.

 

Exactly what head, distributor, and ecu are you using? There could also be a chance that the timing is off, which is a common problem with mini-me's.

On a side note, punctuation would greatly help in making your post easier to read.

 

so you're using an obd0 ecu and an obd1 distributor. that would be your problem. can't mix and match. run an obd1 ecu and do it the right way, or put an obd0 dizzy back on the cylinder head.

 

i have the z6 head and z6 distributor and for spark purposes no offens but the ecus purpose dose the same thing. so i did get the wireing conversion for the distributor so enless the wires on it arent going to the same thing then everything should work the same no mater it being obd0 or obd1 the obd system is just for monitoring the emisions and setting standered simular things to make it a little easyer on the tech.

 

Sorry, but you are incorrect. If you are using an OBD1 distributor, then you need to use an OBD1 ecu. There is no way around it. Trust me, I've been there and done that. You either need to get a P28 ecu, or change your distributor to an OBD0 distributor and attempt to make it fit on the Z6 head.

 

um no dynasty your slightly wrong. if your running and odb1 dizzy run an obd-1 ecu dont ghetto rig it. you were given the proper advice posts up from you if you argue it your just ignoring your simple solution.

there are reason diffrent ecu's work for difrrent car's/setups. go get a proper ecu(p28)

and just for "tech's" sake what sorta dizzy conversion did you get?

something along the lines of the rywire obd0-obd1 dizzy conversion?? casue fyi all that really is is a plug conversion(in a nutshell)


but allin all dude im guessing your using a pm6 ecu based on your original post...if so ill give you some advice that i sure most of honda tech would agree with. dont cheap out and ghetto your mini me do it right and your more then lickley to run in to less problems and will probably fix your dizzy issue


oh um p.s dude when you say this: your highly mistaken the ecu's dont fire a spark for the same purpose based on your problem(please dont confuse that) no matter the setup. the ecu is built acording to how the engine comes from the factory thus allowing diffrent ign. timing based on which odb your running/engine. that's why i bet if you actually got you car statred it would be WAYYYY!!!! off timing,run like crap and a few other issues. so no offence dude but spark purposes sure the ecu's will casue the dizzy to spark correctly...no odb0=odb0 odb1=odb1 PERIOD. dont fight it jsut do it.

 

huh!? that doesn't make even the slightest bit of sense

here. read this, you might learn something

"The PGM-FI (ECU), located under the carpet on the passenger floorboard, is the primary controller for the fuel system. The ECU itself consists of a dedicated microprocessor, a small amount of volatile memory, and the control program contained in read only memory (ROM). The ECU monitors the absolute manifold pressure and the engine speed to determine the basic "ON" time (amount of time the injectors are open and injecting fuel) for the fuel injectors. Before the ECU actually alters the injector "ON" time, the other data inputs (intake air temperature sensor, oxygen sensor, etc.) are used to determine the final air/fuel mixture. After the final "ON" time has been determined, the ECU then applies this to the injectors.

These vehicles are equipped with a Programmed Fuel Injection Electronic Control Unit (ECU). The ECU controls all phases of engine operation. In order to accomplish this control, the ECU relies on the input from a variety of engine operation sensors. It then compares these input signals with those stored in memory to determine what steps should be taken to achieve maximum performance, fuel economy, and meet all emission control standards. The ECU then outputs the necessary signals to the fuel system, ignition system, air control system, and the emission control systems. The ECU also records any malfunctions in the monitored systems. When a malfunction is detected, the ECU will insert a pre-programmed value to substitute for the defective signal, flash the Check Engine light, and store the malfunction in erasable memory as a numeric code. Additionally, should the ECU itself fail, their is a back-up circuit which will control the fuel system to allow the vehicle to continue functioning (Back-up Mode)."


that aside, let me explain why you canNOT use an obd1 dizzy with an obd0 ecu, and vice versa. the reluctor wheel inside the distributor of an obd0 dizzy sends out a specific pulse that only an obd0 ecu can interpret. obd1/2 distributors have a different pulse and consequently can only be used with obd1/2 ecu's. the change in pulse is due to the amount of teeth on the gear within the distributor. just because you think it will work based on some vague understanding of how your car operates, it's not that simple.
