Car was dyno'd at Intec Racing in Kent, WA on a dynojet. They turned on the big fan to simulate the car driving. $45 for 2 pulls isn't too bad imo.

MODS: OBD1 B18C1, AEM short ram intake, Greddy Evolution exhaust, timing advanced 2 degrees.

notice how much bottom end i lost just from not having the IABs working.

car ran better with the p72?

Well thats definitely no good for kenji's business...those are not great numbers you need to wire up those secondaries and it will be much faster and do a compression check on that it might be weak in one cylinder

AzntaggeR

i'm not knocking kenjis business in anyway. only downside to his ecu is the fact that P28s don't support the IABs which gave the GSR ecu the advantage in this dyno which really isn't his fault anyways. after i put on my skunk2 intake manifold i'm gonna run the kenji p28 full time .

you can run IABs thru a P28 it just takes some rigging, go on PGMFI.org for more info

AzntaggeR

well yeah there's that way, but i mean it doesn't come equipped stock.

to realize the full potential of this tune you gotta switch to single runner manifold.

but it does prove a good point

*edit* Nevermind, I'm mixing things up.

i would like to see what you get with a skunk2 and tha p28 chip.

why does everyone know the GSR intake manifold, i mean i have seen some fast drag cars use the p72 mani...........

I just switched to the skunk2 mani and I have a socketed p28 coming in the mail with a kenji chip. Hopefully I can confirm that it is much more benifical to run that program with a skunk2 mani.

Have you already purchased the Skunk2 manifold? If not, have considered a different manifold, something better suited to work with a GSR head?

Those are usually very heavily modified, and the butterflys are removed, as the drag car doesn't see any time below 6 grand or so.

I have a P28 to gsr program my buddy did and he added IAB control and it made 154 whp and 118 lbs torque on a jdm gsr motor with old 2" hks exhaust and a velocity stack/k+n filter. no header has cat in and car passes smog. program made same power up top as stock P72 but low rpms to 6000 is real smooth or smoother. I like the fact we retained the IAB's. if anybody needs one of these programs let me know

EARLdaSQUIRREL

i believe for the kenji chipped ecu to have more of an edge to a p72ecu the motor would have to be more modified, do you have the a/f ratios from those 2 runs, im sure the kenji chipped ecu is running pig rich up in the top end and also the kenji chipped ecu is meant to be used with single runner i/m....

so basically the chipped ecu isnt really good for someone unless they have single runner i/m and better then stock cams, case in point why people with itr motors see gains when going from a stock ecu to a chipped p28, i believe TOM has had great results with his kenji chipped ecu

AzntaggeR

i don't have the A/F ratio for this dyno. i also agree that the rechipped P28 will benefit someone with a single runner intake manifold. once i get the skunk2 intake manifold installed as well as a hondata IM gasket i'll post up new numbers. perhaps someone with this setup can post their numbers just so i can get a rough idea of the gains.

I also posted in your thread in the Integra forum, but where was the VTEC point set on the P28 ECU? I have a feeling that a less-than-ideal VTEC point may have contributed to some of the losses with the P28.

Why is everybody acting like the kenji ecu is so great and defending it. Not saying there is anything wrong with it based on these results because there just isn't enough info, but why run a standard program and try to tune your motor it. Plus kenji's programs that I have seen delete closed loop, he failed to tell me that.

thats how im going to run my setup too, but you really need some cams to get the most out of your skunk2 manifold. im going to try the kenjis ecu with skunk2 IM and stage one cams, then get it tuned with a vtec controller and cam gears.

Looks like B16 #'s besides you putting down a little more trq.

Yes it proves that running a gsr motor with a chipped p28 without changing the intake manifold is a waste of money.

shorty91

you will still probably lose alot of mid range running just the skunk2 IM and kenji chip.

kenji

Using a program that does not support IABs while running a GS-R intake manifold will yield losses in low end power. Japspec hit the nail on the head with his post.

If you were to switch to a skunk2 intake manifold and use my program you will see gains in the midrange on a motor with at least I/H/E.

Exactly now put kenjis program on a b16 or itr setup and you will see the difference.
