gsr_b20x2

ok here is my issue...i CURRENTLY have a P75 with the Hondata s100b (w/ boost) but my tuner is recomending me to go with the s300 set up...i have no prob in doing this...but here is my only issue... i am running a DOHC GSR head (96) combined with the B20 block (98) turbo, set w/ a 9:1:1 comp.ratio....would i be able to just get the P75 re-socketed for the s300 and sell off the s100 chip or is it best to go with the P72... if im not mistaken...the P75 is a SOHC ecu correct... if i stick w/ this ecu (the P75),(if it is even possible) will that give me performance loss...as you guys can see...tuning really does not make much sence to me, so i appreciate any F/b in any form.thx...URGENT HELP NEEDED.

Just sell your s100 setup and buy an s300 setup. It'll be well worth it.

I am not an expert on Hondata buy any means, but the P75 and P72 are the same board (except for components to control vtec and IAB's). I would think that you could tune your car with either one equally.

Just get a P28 setup for the S300 and sell the socketed P75 with the S100 system in it. That would be the easiest way. You don't want to desolder the P75 socket just to put in the S300 header.

The p72 would allow him to keep his secondary runners.
I'm using the p28 right now w/hondata s300 - its

i would sell the current set up as is

and go with a p28 and the s300...if you are usin the gsr intake mani you wil have to use a p72

good luck

few differences that should be pointed out unless you guys already know this

the hondata s100 uses a socket where as the s300 uses pins
if you want to convert an s100 ecu to s300 you would need to desolder the socket and solder in the new header pins

also as for iab curcuitry can be added to an ecu

Ok first off. THe P28 CAN I say CAN run the IABs. All it takes is a little ecu modification and it is very easy to do. The cost of a P72 stock is about the cost of a P28 chipped. There is no reason to get a P72 when a properly setup P28 can handle it just fine.

P75 (Integra non-vtec B18) can do IAB and VTEC both. Why bother buying a P28 when he can do it with a P75. Save your money bud.

PGMFI.org has info on IAB and VTEC in a P75.

It isn't a question of that ECU doing both. It is the fact of desoldering the socket, which can be a pain in the *** from experience, depending on who soldered it. I would still say get a new ecu.
