results from dyno day...

No all of those factors do play a role, regardless if its the same dyno on the same day !! You change any of the factors and the ecu on any car will change its output due to auto correction for variable factors.

The ECU also has a knock sensor and when conditions are not perfect it will pull timing out of the car like crazy ! I suggest this is what happened with almost every car both stock and modified. ECU"s are not stupid ! even the stock Honda ECU is smart and will do anything to protect the engine ! even if that means lowering power output by 50 % !

Take the car's for a road test or on the track and its a totally different story.

Again dyno numbers mean absolute nuffin ! yet some novices believe its the be all and end all !!

I don't know about AUSVTEC, but for references sake, i am running a/c, p/s & non-LSD. But the old schoolers were beyond stock. Mine maybe more than i think, i think i know. :?
i think AUSVTEC might just be stirring up a little friendly rivalry with the youngans...& showing old school :honda: pride ! :P

Nice results Tinkerbell ! Was wondering, would they be comparable to the DC5R's ? (with all the talk of differring variables relating to dyno's etc)

Choongas : LSD was optional on 4th gen JDM Civics.

BLKCRX : have you had any Stage 2/3 Hondata's ?

i think all the transplanted B16a's have been JDM spec, therefor make more horses.... IMO

We use stage 2 / 3 systems for all pw0 and pr1 obd0 ecu's work's just like the s200 system without some of the features... such as 11,000 rpm ...
but iv got a few b16b and b18c7 crx's gen2's running around with pw0 ecu's with a stage 2 system, again very impressive.
Any Hondata dealer in any state can do stage 2/3 systems also for older Honda's

my car owns DC5's in a straight line...

Is that modded DC5R's? Like 02typeR's 112kw beast?

i will take on any modded DC5 in a straight line...

it is all about area under the curve, not just peak power number...

see how my graph has a big bulge, it is much more prominent than the DC5 bulge...

and it starts much earlier...

BTW - 112kw is nothing for a DC5 - they should be hitting 130+ with IHE, some cams and proper tuning...

James - how is running the B16B's and B18C7's off a PW0 ecu? which distributor are you using?

it really sounds very strange running OBDII engines with pre-OBD ecu's

you obviously put pre-OBD sockets/sensors on the engine, but do you just ignore the crank angle sensor and such?

ALSO (and more importantly) - what makes you suggest that almost all the 'low' power figures on the dyno day were due to knock retarded timing?

i'd love to know about the knocking thing as well, i was under the impression only vtec integra's and some CRX ECU's even had a knock board. Not sure whether the Type-R ecu's are equipped with it but i'm guessing they are.

I think other factors are the cause of it, rather than retarding due to timing. Considering that the figures seem 'low' across the board.

comes down to power to weight ratio in a straight line thou doesnt it?

the LS is lighter then DC5R?

Ha ha ha...
Yeah?

Wanna race for money? :D

MAD
where when ?
hehe
