I have been skimming through ECU pin out to install the Greddy Ultimate but found nothing useful on Greddy Technical site..

The manual does not show which is the AP2 ECU.. But I gather that the Apexi RSM and HKS SLD does have ECU layout for AP1. Some named it H-8a some name it H-8.

The way I see it, compiling from both Apexi and HKS, I deduce that the manual in Greddy did have the AP1 layout but did not mention and it is found under code H-6.

But the diagram are all crappy so I rerawn them in excel.. Can I say this is the same for AP2 DBW as follow:

 

Ok where's the VTM Sig located?

And our 4 injector signal should be looking at individual injection correct? So what is this group injection about? Am curious to know.

 

Ok i think its confirmed, not AP2 ECU layout.. I just dismantle the ECU and took a pot shot..



So interpreting from the cable POV, its totally different..

 

Is this the ECU Code?

 

Argh.. after having a clear mind and skimming thru pages of diagram, finally see a fitting one to the above pot shot. Page 30 of the Greddy manual, diagram H7 belong to AP2. Will do another excel for better viewing later..

And thus far, page 30's H7 diagram:


How can the official technical site provide such crappy xerox image?

And does this mean AP2 ECU is utilising the wiring of K20A as shown from chart below? Jus different mapping. I rem reading from Hondata website that they actually modded K20A (Kpro) program to suit AP1 but require certain add on of OEM parts.



Are there anyone else running Ultimate? I am free so feel like wiring up myself before taking to the tuner to tune.. Any advise?

 

Here's the clearer layout:


Adapted from K20A layout. No mistake?

 

hi, any idea if the Ultimate can remove the speed cut and shift vtec rpm?

 

nobody got the idea?
