i have a 94 accord with a h swap im having a problem with the rpm tack its only reading up to 6,500... i have a chipted ecu at 8,000 rpm.. what could be helding it back??? thanks

 

are you using a p13 ecu? is your vtec engaging at all?

 

im not sure what ECU it is i think a converted P13,got from phearble.net and ya it pops at 4k

 

What could the problem be??

 

i would get a regular usdm/jdm p13 and go from there. thats real low for it to be engaging btw.

are all your ground good? oil good?

 

ya every thing is good and i told them to put it at 4k

 

Could it be any thing else??

 

i think its the gauge its reading rong how could i fix it??

 

Either get a new one or remove the cluster and re-calibrate the rpm tech.

 

How can u re-calibrate it?? What u need to do??

 

does the motor feel like it's pulling after 6500 or is that now it's redline ? My vote is for you to get the USDM virgin P13 ECU and see if that changes anything.

Why did you want a lower engagement of VTEC ? - your car did not even hit the dyno for a tune so that low of engagement screws everything up.

 

Ya it's going past 6,500 cuz when I race my friend with same thing as I do we sift at same time and his car says 8,000 rpm

 

Bump

 

other sugestions??

 

hey i have a 95 accord with a h22 swap and the rpm doesnt read properly it will pull sweet till it gets to 5,000-5,500rpm then die off and if i run my car and try to pull 3rd gear the vtec cuts off any suggestions??
