please look at my graph and tell me what going on..im not good with reading the graph for sure...
mods are:

vafc2
header
cai
exhaust 2.5
manifold
stock fuel sys
stock ecu...
everything else are stock also

here are the graphs: left is 1st baseline run, right is the graph after tuned run 16th:
vtec-set point at 4800-4900 for run 16th
vtec-set point at 4400-4500 for baseline run 1th

 

doesnt look bad...

was there tunning ?

 

yes....tunning only with vafc2....ecu-obd1-p72 is not chipped at all or with any hondata units...

 

looks good to me

 

Did he say "1th"?

 

pretty nice number, and can u be more specific on ur mods
like what kinda header with ? collector, etc

vafc2
d16z6's CAI, i reused for my gsr...small as hell, i think the diameter is most 2"
header duplication of type r with slightly smaller exhaust runner 4-1 with 2.0" collector, but then i custome the header's collector. I cutted it off, and make it longer and increase the collector diameter to 2.5"
Exhaust piping is mandrel bending 2.5, with stock path...
Blox Manifold
Dynoing with catless..

that's it i guess

 

Looks like a freak motor. That is pretty strong for those mods. How many miles on the B18c1

 

Was there a wideband O2 used? If so, is there an A/F graph for each chart?

 

yea that thing is puttin down some serious numbers. Wow. My b17 with 90k on it dyno'd at 150hp-110ft*lb. And i only have an i/h/e.....i wish i could get numbers like that

 

yeah.. it'd be nice to see the a/f line.. good #s though

 

those numbers are pretty good for a gsr with basic bolt ons..

the motor is 96 sedan GSR-4drs...mileage was unknow (i was guessing about 130k miles) but decided to rebuild it to stock to be safe...after rebuild the motor is current at 4.5k miles

sorry i was decided to get windband 02 before dyno..but budget shortage..so . But by some sympton, i noticed my car is running little rich...after dyno im not sure. One good thing is..i think i got a better mileage out of 91octane Shell's gas


oh better..what about some spike of the tq's curve...? anyone got any idea?

 

What the crap heck... I dont think I am putting that to the wheels...

 

are those spikes on the tq curve of the 16th run from approximate 3.5k rpm to 4.8k rpm are normal?

and some spike on the 16th run of actual hp from 7k to 8k rpm are normal too? they look irritating to me

I wouldn't worry about the 1st baseline run and it's "spikes". Most of those were smoothed out by the 16th run anyway so it's not relevent anymore. But I'd say those 1st run spikes are fairly normal with no tuning yet.

The spikes at the end of the 16th run at the higher rpm's are minimal so I wouldn't worry about them. Don't get caught up too much with graphs. You got very nice numbers and good increases throughout the midrange and up.

 

Im guessing those are corrected graphs. what did you get with your uncorrected graphs?

some say because of my D16z6 CAI (about 2.5") has a slightly smaller diameter throughout its piping, and because of CAI is usually stroking the motor in topend. Some also talking about the Knock sensor is also a cause, however, i do not know why.

Cjohson, the left graph was uncorrected graph, and the righ graph was corrected by dyno tune.

 

Did he use any other VTEC points? also do you have any future plans for ecu to take better effect of the single runner maniifold?

ahh im sure he did but best was at 4800rpm for mine. for sure i will go with hondata s200 with either my p72 or p28 chipped. Haven't decided for sure on which one, since i do not have a good background on p72 vs p28 with hondata tuning. So i will need to read up more about 2ndary butterfly that causes the curve to flatten out little bit 5.3k rpm or 5.4k rpm.

since my motor seems healthy to some of the viewers, so i will take the advantage of that and the next step i think i will go for camshafts and camgears with some FPR wiht hontada s200 with my stock p72.

sound good to anyone?

 

bump for a question. Do my graph look like needing some more fuel at top end?
