which should i hook vtec up 2?

ok have a 91 dx with a d16y5 vtrec-e motor now ive read that i can do a si ecu from the 88-91 ed.an just get a msd rpm actdivation switch?or should i just wait an do the p28 ecu an obd1 obd0 coneversion harness?

vtec opps my badd

I would day wait for the obd-1 ECU

I agree, and get the obd0 to obd1 jumper harness. It's about $100 but you'll think yourself when u see how much easier it makes wiring

Or go the other route and get a vafc

vafc? i notice that when i was researching on a obd0 to obd1 harness.....wat exactly is that for...would that interfer with my hondata setup?

OBD1 harness makes it so u can run an OBD1 ECU...


But why did u get a VTEC-E engine?

Oh my fault... A VAFC, stands for VTEC Air flow controller... Pretty much like its name implies, it allows u to adjust your VTEC engagement point, and your air flow, and in turn your fuel... They should be profesionally installed and dyno tuned... Not sure how they work with Hondata...

But see this page for more info:

If u have Hondata, then u shouldnt need one tho...
