I

Hope this work , I am trying to post my dyno graph of a Lsvtec with 12.4 compression ericks ecu and so on . This motor made 175 whp and 130 lbs with B16 cams . When I changed cams I had to lean fuel out to make this power . A/F was 12.9 at first them 13.5 at end tried all cam setting and never made more than 1 whp difference . Something holding the motor back but what is the question .

Here is the graph for the same motor and B16 cams

stock head..? and what cams did u switched too...? post ur setup ppl migth be able to spot something

 

I thought the post name will tell you the cams ? I went from B16 cams to Toda B . The set up : B16 head with Portflow valvetrain
B18 B with .250 longer Eagle Rods
Wiseco Pistons 260 psi all cylinders
ITR Im with stock TB 58mm
JDM DC 4-1 header
Stock injectors and Vafc ( I am aware these are small but the motor
made more power taking fuel away . )

 

oops...missed that srry..

 

Please I am up for suggestions .

 

try a fuel pump and new spark plug wires. seems like you are breaking up on the high end of your power band. either you're not getting enough fuel or your ignition isnt firing up top. i would check those two out first. make sure that your tuner sets the fuel pressure, ignition timing, cam timing, and vafc or hondata. i really doubt that your motor made more power by leaning it out. i would set your fuel pressure to 46 psi with the vacumm on. then from the igntion timing must be set to maximum hp and torque on the dyno. same with cam timing. since you already have a vafc that should be able to fine tune your settings after you're all done with the 3 ive mentioned. hope this helps

 

I have checked my wires and they are fine but it could be a ignition problem I will
try new plugs . The motor did make more power by leaning it but that could be the fact that it might have weak spark making it not able to burn additional fuel . I was leaning toward igniton . Thanks for the input .

 

This is the same motor with B16 cams . Not vtec enagagement and how the toda seems to have none , in fact I bet most will not be able to tell the vtec engagement on the todas .
