ive read alot about this searching but i havent really found the answer im looking for, all that the activation switch does is acitvate the solenoid and doesent mess with the feul maps right, is that safe or will it damage the engine, im running a pm6 ecu with my mini me setup and dont ahve the moneyu for any conversion harness or pm8 ecu any hel[p would be appreciatied Thanks

 

Save and do it right.

 

dont do the msd, you have like literally half the vtec power, save and do it right man, you may have vtec but not the extra fuel for it...

 

Ya...

MSD =

I'm using the MSD right now. When the VTEC activates it just runs kinda lean and i don't notice much of a power gain.

sorry to say but yes, runs lean, power gain is ok
I'm doin a port polish y8 head with crane cam stage 1 & msd...
not an 'eye opener'.
you really need a better & more supportive control factor, msd to me is a sh!+
rig, I won't lie , I'm doin it but I can see its not the answer, it a quick fix...
save $ do it right
I am

 

The reason the engine runs lean is because you're not enriching the mixture after vtec activation...the MSD unit just activates the selonoid.

 

I was running a pm6 ecu on my mini-me a while ago.. What I did was change the fuel map after the engagement point and let the rpm switch turn it on and off.. So when the switch turns on the solenoid the fuel table is already richened up for vtec..

 

i have a cx. I am going to ran hondata s200w/boost, now would i be able to run the non-vtec ecu, and run the msd thing. And that way it will be safe, because i have the hondata to richen the fuel. I don't have to do anything else with it, do i? My LS ecu is chipped with the hondata, can i just plug that into the cx harness?

 

well, hondata of course would have to be tuned
but yeah, ls ecu, can it activate vtec?
if so, use it but remake the maps of course

 

I mean can a ls ecu plug right into the cx wiring harness, and do i have to mess with the o2 sensor.
