I have a 91 Si I am putting in a 95 stroked lsvtec. I am running a DTA standalone engine management to will completely control the motor and all sensors on it so I have removed the factory Honda ECU.

My question is what is controlled through the ecu that will not work now...Such as fuel pump? or anything else?

FYI
I am running no A/C
No Heater
No radio
No emissions

 

Anyone?

 

not quite sure about everything i am not really familiar with your standalone but some systems don't support vtec.

 

Look up the ECU pin-out for an OBD1 engine and you should find some of your answer there, depending upon what comes and goes from the ECU.

I'm not honestly sure beyond that.

 

Yea I have that covered..Vtec works off of a switched 12v power. Kinda like a shift light. I am more worried about fuel pump, main relay...etc..
Thanks

sure sounds like a good project give us a build thread when you are done i would also like to see your spark maps if possible. not gonna use standalone on my civic just curious.

 

the main relay needs a signal from the ecu to activate the fuel pump.

 

so I could just run the fuel pump to a toggle switch?

 

throw that bitch on a toggle and be done with it
...it'll work

 

...after all, i have friends who have vtec wired up on a wide open throttle toggle ...lol, how ghetto is that?! but a fuel pump on a toggle, is actually kinda cool.

 

haha...vtec on a wide open switch dose not seem like a good idea...i will probably just wire the fuel pump to a remote 12v so It just comes on when I turn the key.....

 

come on man, keep it gangsta
