just bought a s300 ecu in a p06. car is a eg coupe with a jdm type r in it. has no vtec.
all the parameters are right.
car runs perfectly on my friends p06 s300 ecu.

any and all would be great
thanks

 

Who did you buy the s300 unit & ecu from ?
What happens when you try to engage vtec ?

 

A P06 is a non-VTEC ECU. If you want to use the alternate VTEC output you will have to wire the correct output you choose to a relay that activates the VTEC solenoid.

no not true i have another s300 p06 ecu and it works perfectly. i figured it out though by comparing mine to the messed up one. one of the things your supposed to put a little resistor that is supplied in the s3 kit. and instead of doint that they just hard wired it. but if anyone knows what ohm resister its supposed to be or if its even a resistor. it would be nice to know. so i could go pick one up from like radioshack and do it the right way.

thanks

 

The only way you can run vtec on a non-vtec p06 is by adding vtec components to the ecu or by using an alternate output & relay to activate vtec per spunkster's recommendation.

 

ok could i get some instruction on how to do that.

and an explanation to why my friends p06 works perfectly.

thanks

 

Can you verify that vtec components have or have not been added to the ecu?

This will answer your question. If you can get a picture of inside the ecu that would work too.
