-Who has ran 8 injectors on hondata. What did it take? I've read some people just running them in parallel on drag cars which is what i would use it for (drag only)

-Can you run 4 - 2000 and 4 1000's in parallel (ex: a 2000 and a 1000 in parallel) effectively making it 3000 per cyl?

 

You can wire up the 2nd set of injectors to come on using an output on the ecu.
Condition based etc. Most people activate the 2nd set of injectors in the high cam map only using a relay/output etc.

I would highly suggest using the lean cut feature if you are doing this.
Make sure to set the load & trigger time accordingly when using lean cut or you will hit it when there isn't a lean condition etc.

 

You are turning the second set of injectors on 100% of the time using an OUTPUT?

You could power the second set using a separate relay/12 volt source, but it would still have to trigger both sets using one injector driver which I would be worried about heating up the drivers in the ECU in not too long a time.

I know Locash at one point said he ran two sets of ID 1000s off the ECU directly, all the time (even at idle) but you would have a lot of playing to do with Injector Dead times, etc...

It should work...you just have to see how the ECU would hold up

 

IMO it would be easier to sell the Hondata unit and purchase an EMS that can control 8 injectors with separate drivers. Even better would be an EMS that has a 2 stage injection ability.

AEM, Motech, Haltech or even MegaSquirt all have 4 - 12 individual injector drivers.

 

yea yea yea, AEM i know. Maybe next year. I really just need to increase my voltage output to the pump for the 35+ psi range and ill be fine with that i have.

 

I have never ran 8 injectors on a honda ecu.
I was giving him ideas how I have seen other people successfully do it :-)

 

I have done it before, but you do have to be careful about overheating the injector drivers. You can install a fan to keep them cool. You can also only do it with high impedance injectors. It is not the best way, you are better off with staged injection, but it does work.

 

The OBD1 ecu will handle 8 ID1000's in parallel, I've done it many times on multiple race cars. I don't know if I'd do it on a street car though.. The K-series ecu will do it as well, but since there is only one injector driver component on that ecu, I would put a fan on it to help keep it cool. Dont want that thing desoldering itself from the ecu, lol.

 

lol

 

so could one parallel a set of 1000's with a set of 2000's? I would DEF get a fan for that thing, and prolly make sure a spare s300 is nearby LOL

 

Locash what about 2 sets of id2000. Would the 2000 just be to much.

 

a high impedance injector will be a high impedance injector...750/1000/2000. i did it once and put a fan near the driver, exactly as Turbogixxer said. i don't know about the tunability at idle and what not (i dont tune), but electrically as Joe said, it's really not a problem.
