would i have to get a dizzy jumper harness too if i get the jumper harness

 

 

you can use a distributor jumper harness, cut n solder on new distributor plugs or repin and match the wiring.

thanks guys just wanted to make sure and double check....
is it worth to go obd1 or just stay obd? dnt want to waste my time but i cant find a pm6 or pr4 ecu anywhere...the pr4 i was using burned out on me

 

its deff worth it, better tuning abilites

 

For tuning it is definitely worth it. The obd1 ls ecu is still a pr4 though.

 

so would i just b able to tune the p28 or would i still have to snd it out to hondata to get it proper for a tune?

 

You don't send an ECU out to get tuned.

ALL engines are different.
All of them... even if it's the same kind of engine they are still just a little different.
You hire a tuner and they tune your ECU to match your engine.

Just slapping a chip in or putting some random code in your ECU that was NOT tuned for your engine in your car is not going to give you the best results.
It might be 'close' (or might not be). Makes me laugh when people buy a Mugen chip off eBay and wonder why their car runs horrible.


.

 

ok thanks guys..you guys made me realize that it is worth it....and wat u said about the random chip n code is funny...i seen some people chip their ecu and most of them run good for only a month makes me laugh lol

 

That's just a bad/cheap chip as in the physical chip wore out.
To reiterate - take it a bit more extreme. Figure the Mugen B16 engine. All the internal work and the custom bolt-on's with 1000's of hours R&D for an engine -capable- of dishing out serious power.
Then they tune the fuel and ignition maps to extract the power from the engine and they they have it - the Mugen chip for the Mugen engine.

Putting that Mugen chip into a bone stock B16, or even a mildly built B16 is NOT going to give the same results that were made on the Mugen engine. different engine, different parts, requires different tune.

 

lmao
thanks alot for that very useful information

 

The "mugen chips" on eBay are normally a cheap replica of the real chips. The mugen chips come with a Basemap on them. The Basemap normally gets rid of the o2 sensor and turns up the fuel a lot the reasoning for this is so you can start your freshly built motor running and get it to a tuning shop without it blowing up. The basemaps aren't really made to be driven around on forever and if your buying them from eBay most of the time they are a single burn rom chip that can't be retuned later. That is just what I have learned about cheap tunes. Best way to tune the car is convert to obd1 and have an s300 put in any obd1 ecu like a p28 and then have that tuned for your motor.
