He sure can but check this out.Thank import review.com for this.
GSR ecu vs. lude ecu
This is an OBD1 Prelude VTEC motor with (blue line) H22A ECU, (red line) GS-R ECU. This motor does not have any Fuel controllers such as a V-AFC from ApeXi. It does a have a fuel regulator. But nothing to change VTEC with...this is your standard, low budget setup...
Blue line: H22A ECU, is the daily driver choice. The power is smooth, there is not a noticeable lag when you go up the RPM's. But the fuel is not perfect for maximum power, as you can see up top. The VTEC comes in later, on the stock ECU, so that is why its smooth....
Red line: This is the GS-R ECU. VTEC comes in earlier....so you get a HUGE lag....but after that...the power screams and in the high RPM, you have more power considerably. THis would be a better pick for drag racing, but a little uncomfortable at about 4500 RPM, because it lags. Your ripping up to 4400 RPM, then it just falls on its face...then it screams again...but its good for racing.
It should be of note that the Lag cannot be fixed with simply a V-AFC. This is so because the timing and fuel curve cannot be changed enough to make it all go away. Timing at all...What can fix this problem is a Hondata System.
The results speak clearly....
The motor has a milled head, all the bolt on's, stock cams, stock intake manifold, S pistons. Cams have the sole effect on VTEC lag....The cams are obviously too big for the GS-R ECU.
