Default TurboEdit and Vtec

I am chipping a PM6 for a buddy of mine. It is going into a CRX with a mini-me setup. I have searched and I can't find any BIN files that have high and low cam for the PM6 running a SOHC motor. When I try to make a base map using NG60 I select Vtec and I still only have 1 set of maps. Can someone point me in the right direction? A link?

We plan on using the 1 wire AC for Vtec

Come on guys. I have been reading the PGMFI board till I can't see any more. I have done searches on here and I have read alot about the"hardware" part of this but I can't find anything about the fuel and ignition maps. Do you use a high and low cam maps for the SOHC ? If not what do you do to make the PM6 maps work with Vtec? I do try to figure this stuff out myself but I an having problems with this. Any help would be GREAT

search ****!.

split the maps into 2. eg low cam up to 5000, high cam for the rest, but all on the same map.

OK, so I use a P28 SOHC map and copy the low cam up to the Vtec engagment and then copy the high cam after that? I assume this would be for the fuel and ignition, right?

you have to be careful when just coping maps from what code base to another because the collum heading are differnt. if you want to use the p28 maps you should make a excel doc that interpolates the values over to the ng60 code base. I think of linear interpolation just as Y=mX+b form. so you find the slope between the two known points and the intersection (b) is just where the line intersects the first point on your slope. I would just draw a cordnate axis to figure it out your self. Who would ever thought basic algebra would make your car go fast.

OBD1 maps will not "copy" to OBD0 maps.. Row/Column numbers are different, not to mention Honda uses an arbitrary numeric to represent fuel pulse in OBD1, where as, OBD0 uses milliseconds. You'll have to do some work to convert the maps.

Your best bet is to start with PR3 maps, and slim back the fuel about 2%..

I'm pretty sure he would think the same thing since it's the only way to do it.
