JRSC tuning issues? PLEASE HELP

JRSC tuning issues? PLEASE HELP
I installed my JRSC on my CRX. I have a 91 SI with b16a i/h/ chipped ecu.
I am having problems with it running extremely rich. I am getting about 100 miles to the tank. I have a light black smoke that smells strongly like gasoline when i'm at idle.
problem 2. My idle is around 1750-2000 rpm's
I called jackson racing and he suggested trying a stock ecu. I did that and got a little bit better gas mileage, but it still was very noticeable running rich. the ecu was reprogramed to run a more aggressive fuel map on the lower rpms.
I retarded the time as close as i could, as suggested but jackson.
I have stock injectors and stock fuel pump.
any suggestions would be greatly appreciated.

I think thats kinda odd running rice is usually never a problem with Forced induction on stock pump and injectors.So i would be glad its running rice so it wont lean out and cause any problems.As for the high idle simply take a screw driver or wrench and adjust the bolts/screws on the thortle till its how you like it.

Re: (91hob20hb)
If you are running OBD0, buy a Zdyne. If OBD1, buy a Hondata.
Then call the manufacture and ask them to recommend a dyno tuner in your area (your "profile" says that you live in the USA, and that doesn't help).

Re: (hyperlite1080)
sounds like you have problems with your map sensor, your ecu is not reading the boost properly (honda ecus are not suppose to read the boost) so the ecu sees all this extra incoming air and is dumping fuel to compensate. are you using any check valves? i would start there first, This is why most people use a missing link, i think even jackson has a map sensor solution on there website as well. technically you could use a vafc, but i wouldnt do this, unless you have an extra block on hand, id check in the boost forum.
my map sensor fried, and i went from 280 a tank to 67 miles a tank, and my bumper turned black in a week, im willing to bet almost anything that your problem is related to the map sensor.

Re: (slowpokesi)
Hyperlite;
The reason I pointed up where you live is that somebody in Ohio may know of a local tuner that you can go to.
I live in Los Angeles and would recommend Shawn Church at Church Automotive Testing (he does the dyno work for Honda Tuning magazine). He personally owns an EF with Jackson and "D" motor. (he gave me a ride and it's fast!!) Of course, you are not going to drive to L.A. so it really doesn't help.

Re: (slowpokesi)
Well if my map sensor is fried wouldn't i be getting a check engine light? cus i am not getting a check engine light.
I called Passen Motorsports in Columbus and he suggested getting a AEM EMS, and to get it dyno tuned, but i don't have the 800 dollars it would cost to do that.
So anymore suggestions?
Oh and my idle, i adjusted my throttle cable and nothing happened, still stayed at 2000 rpm's, and the cable is loose. ?????
Help some more!

Re: (hyperlite1080)
i didnt say your mapsensor was fried,
i said your map sensor is probably reading the boost, and it is not suppose to.
you didnt awnser any of my questions about your setup soo good luck.
of course the shop is going to recommend an ems, that some money right there.

Re: (slowpokesi)
I am assuming i'm not using any check valves, cus i don't know what they are. I was wrong about what the shop suggested, they suggested getting a Greddy Emanage. and then letting them tune it, i'd still prefer to avoid that.
So any more suggestions slowpokesi? how do i make sure my map sensor isn't reading boost, or what do i do to fix that problem?

Re: (hyperlite1080)
if your not using check valves then this is probably your problem,
you need to get a synapse missing link they make 2 kinds, one for the trottle body, and one that mounts on the firewall.
you need the kind that mounts on the firewall. it looks like this and cost between 50 and 90 new, id also post this in the forced induction forum, someone else might have an awnser.

Re: (slowpokesi)
For some reason i can't post in forced induction, i tried already.
thanks i might try that before i buy the Greddy emanage.
what exactly does a check valve do?

Re: (hyperlite1080)
well check valves keep your map sensor from reading boost, you usually have to have like 4 or 5 of them to accomplish them, but setting them all up is kind of complicated.
The thing i posted basically eliminates the need for a check vavle, but still accomplishes the same task.

that website would be helpful if it gave you a list of everything you needed to get started, ive gone through it a few times, and i feel like im reading japanese.
since you seem to be the expert please breakdown everything i need to get started.

Yeah, i tried reading it, but all it gives you is the software, and doesn't tell you step by step on how to get it to work or what you need
any info would be greatly appreciated.

while turboedit is awesome engine management, it does all come with a cost: IE soldering an eprom socket onto the ECU, buying a programmable EPROM, and buying a EPROM burner, in edition to the time spent attemtping to tune it yourself... looking at $300-$500 easily

once again, this will solve all your problems and make you very happy. invest a little money into a burner or find a friend with one and take it to a dyno. you will be all 's
good luck

Were do i buy a burner or all the stuff i need? I'd be willing to do that. Does anyone have a post on this anywhere on how to do it and get it installed?
Also, I am going to try to just buy the thing Slowpoke said to buy and spend less money first.
But i'd be all for doing the turboedit deal if there was a post on how to do it and a place to buy all the stuff

Re: (hyperlite1080)
if you cant figure it out yourself.. from the turboedit site and pgmfi.org.. then you are safer to not even mess with it..
If you can't do things yourself.. they cost a lot. A LOT
sure the missing link will work.. so will check valves which cost $3 at the most...
Search and search

Re: (hyperlite1080)
read all of turboedit page, then check out http://www.homemadeturbo.com/forum goto the engine managment forum and read up on turboedit there. if thats still not enough info check http://www.pgmfi.org and read into their forum, its a bit harder to follow, but it's a research/development forum. burners can be found on ebay...or at stores online, just look for a 28 pin eprom burner/programmer. and a low profile 28 pin zif socket. i had all these links saved, but i had to reformat the comp. and dont have them handy. the chips you will need can be had on ebay for fairly cheap as well, 27c256 are what to search for on the chips 200ns or faster, which is marked -20 or -200 on the chips. and play around with turbo edit and get to know how to tune, you're set, lots to learn but its great if you're not boosting over 9 psi.

Somebody said about 3-500 bucks for everything? Will i be able to change when vtec kicks in and change my fuel curve?
Thanks
