you cant buy the neptune software, only authorized tuner shop have access to the software. that means money everytime you need a retune.

do you think you could make the fuel map base 100% off tps. not half load and half tps like the current version offer in crome.

jdogg, so far i havent found any motorcycle itbs that are 50mm..
the ducati 748-916 itbs are 50mm at plate and taper down to 44mm.. you'll have to do ALOT of fab to make them work on honda setup as they come in twins.. so u'll have to buy 2 sets and then figure out how to hook them all together. i'll post a pic of mine here soon..

i bored the taper out of mine to 50mm..

blundar

yes is the short answer. It would still be wise to have a MAP sensor for the deltas and corrections based off of it, but running purely TPS indexed tables is possible.

THERES A WAY TO RUN YOUR FUEL MAP OFF OF YOUR MAP AND/OR TPS SENSOR WITH CROME. U COULD TRY THAT. I TRIED THAT AND RAN I LITTLE RICH BUT OVERALL FINE.

i think people who use aem EMS or Neptune to tune itbs use only TPS indexed table. i don't think you would get the best gas mileage because you can't use close loop.

how do you think itbs are controlled on motor cycle? i know they have both MAP and TPS sensors.

JDogg

you DO need to have the map sensor in there. for narrow throttle angles and a nice idle you need to blend the map signal in for those areas. im not sure about other systems, but this is really simple to do w/the aem ems.

I'm working on getting a couple of base maps from a couple of different CROME tuners to work with. Cheetah is working on one, and my buddy Lenny will be tuning my car tomorrow using version 1.1.0 and we'll see from there. I agree with JDogg though. using the map signal at low throttle is theoretically a must to have any decent drivability, and yes it would be much easier with the EMS, but I'm far too poor, so 1.1.0 will have to do for the time being.

let us know how it turns out, and post your base map for version 1.1

how much wuld u charge to make those for a ls

here's where you can get a base map for itbs with crome v. 1.1. don't forget to replace the new itbs tool script. i'm going to give it a try tonight.

awesome!

kendall.
wat length are your runners?? base plate to velocity stack tip??

sweet setup too!!!

Kendall

Alright everyone, here's how the tuning went:

The car baselined at 140 and 105 with the ITB's using the fully tuned map from the manifold setup which made 157 and 113 previously. We screwed with the fuel and we got 140 and 105. We screwed with the ignition and we got 140 and 105. We screwed around and screwed around some more and finally got 141 and 106.

Then we put in some CTR cams. HOLY ****!!! 163 and 116 using the same map

Then we put in some Skunk2 Stage 1's, 171 and 118 using the same map

Then we put the stock cams back in and started measuring airflow. It turns out that the stock cams are so restrictive on this setup that it's building up rediculous pressure and the air is actually trying to come back out of the runners, thus killing power.

So then we said **** it, and put in a very simple map that Lenny put together for drivability purposes and I was settled with 140 and 107.

Now, let's see what I have laying around to sell so I can afford some Buddy Club 3+ cams and make some real power.

Also, heat soak became a serious issue on the dyno so a Hondata intake manifold gasket or two will be next on the drawing board before the cams.

10 inches exactly from gasket to the tip of the velocity stacks.

Kendall

Make a long story short: If you do this setup, be sure to buy cams.

Dang Kendall, it ended up making great numbers

i would think the tuner would give the buyer a copy to do themselves also. hope they do. i would have to check on that.

even if the engine is basically stock? i am waiting on some parts for my itbs to come in, and hopefully it will be done soon. but you would suggest some aftermarket cams with the itbs? what about a stock gsr with jun3s? that is what i have right now, but i would think that is over camming it. any idea if the cams would run fine with the stock gsr or not would be great.

It's not exactly difficult to raise the compression without tearing into the bottom end. A thinner headgasket and some milling can easily yield 11:1 compression. I'm personally a ***** for the Buddy Club cams as I've had the opportunity to play around with a couple of sets on the dyno. I definately believe JUN 3's on an otherwise stock GSR is overcamming the hell out of the motor. Remember that the US market GSR only has 10:1 compression and that the JUN 3's aren't anywhere near happy until much more than that, even with ITB's.

I'm looking to get a set of the Buddy Club 3+ here in the next couple of weeks, but also I'm looking at using the headgasket/milling combination to try and bring the compression up to about 11.2:1 in order to pull out some additional power. We'll see when we get there, but until then, I'm stick at 140 hp.

Kendall, is this a b16 engine?

here's a post about neptune, the creator say you can't buy it.

Yes it is. A JDM second gen motor to be exact.

Speedz

not too bad.. do u know which b16 cams you are running? i had some b16 auto cams in one head i got some time ago.. just going to some GSR cams made big difference

Kendall

The cams are the JDM second gen manual trans. cams. I tested some GSR cams a couple of weeks ago and my midrange increased by 2 or 3 all the way up, but my I lost 3 peak hp. I would have liked to have kept them in, but they were a friend's and I was only borrowing them.

On another note. My Maxim Works header (stupid expensive rare JDM bling) came off today in favor of a Toda header. I don't know that I'll make any more power, but I won't be back on a dyno for a while anyway so I won't be able to find out.
