So I know the JR FMU is trash. I get that. Dont remind me. But its my only option without shelling out another 1000 bucks for s300 and dyno time so bear with me

I have an B18B1 with a JRSC (M45 blower) and a 10lb pulley. What do I need aka what came with the kit originally? Ive heard the phrases MAP controller and FMU thrown around. Everyone talks about the FMU only so what do I actually need??

Thanks

 

the kits come with the FMU that piggy backs your factory regulator to raise fuel pressure effectively increasing your injector size on a 5:1 ratio (5psi of fuel pressure for 1 pound of boost), there is also a pressure switch that goes in the intake manifold attached to a relay that runs inline to your IAT sensor that you splice in, when the pressure sensor hits positive pressure it triggers the relay which pings out your IAT voltage and causes the computer to retard the timing by something like -4 degrees or so, i forget what its set to from the factory.


I know that they have extras like a map controller and such but the bare basics are done with the map never reading boost, only vacuum, because the factory ECU tables do not have boost columns for positive pressure for fuel and ignition.


That being said, hondata is only one alternative, you can chip your ecu and run hulog and ostrich and crome free addition (and freelog for datalogging) for much much less then 1000 bucks and not need any of that junk that JR provides, you would be doing in the proper way by tuning your ECU to read boost from your map, and run larger fuel injectors properly.

I have the same setup as you and I run a moates demon and ectune, none of the JR fmu and IAT trickery, and my car gained assloads of power over the FMU setup, because you can get proper ignition timing for power, and not run pig rich or dangerously lean because you have precise control over fuel conditions.

Should you decide to go the route of the FMU anyway, make sure you have at the very least a wideband gauge and a boost gauge so you can dial back the FMU so the car will at least run in an acceptable nature.

 

Oh damn. didnt realize that the JR system ran that way. Sounds sketchy really.
Thats a bitch tho, I just looked up the demon and ectune and I really do not know what Im looking at nor what I need. Im not totally familiar with either of those two items.

But from what I gather, I run the demon/ostrich with a chipped ecu and then tune on ectune software. But instead of having to burn chips with s200, the ostrich will let me tune on my PC computer/upload someone elses tune.
And I do have a boost gauge and a wideband is on the way. The wideband will help with tuning/protection, correct?
Price wise i cant figure out what I will need to spend. Obviously the emulator but what about the software license?

Sorry about all the questions as I am not to familiar with this program setup

 

the wideband will tell you whether or not your rich or lean, that will help in adjusting for the proper air fuel ratio for power, 14.7 in vacuum getting progressively richer till you hit 1psi and from then on 12-11.8 AFR for boost.

the demon is an emulator board that installs in the socket of your ecu which takes the place of the eeprom chip, its designed for programs like neptune and ectune.

the ostritch and hulog are similar in design however they are seperate for datalogging, and programming, where as the demon is all in one.

the disadvantage to the demon is that crome free and freelog do not work with that particular unit (where as hulog and ostrich do), which means in order to use it you have to shell out for a neptune or ectune license (i do not recommend crome pro because support for it has been abandoned by the creator)

all OBD1 ecu's from honda come with an additional section of the board that allows for chipping, you buy the chipping kit, and solder it all in and you can activate this section of the board for custom programming

the tuner programs allow you to create new basemap files and add on additional parameters and make adjustments to everything that the factory ECU would have and then upload it to this separate chipped section and run that rather then the factory tune.

for instance, here is a pic from ectune



it does require a bit of a learning curve to do this on your own, this is why its always recommended to go to a dyno tuner to have this done so they can get the most power safely from your setup

 

I have a p75 right now that was prepped for hondata s200. its got a 2x2 connector coming out of it. Is that different than any other chipping setup? Never seen any other one before honestly.
Also, from the ectune website, the stock honda map can read ~10 psi of boost. Since Ill be running a 10lb pulley i technically SHOULD be alright. But should i upgrade to a 2.5 bar map just to be safe?

 

the stock map sensor will see 11.3 before it maxes out IIRC

 

depending on where your located you could easily surpass 10psi during the winter months due to the density altitude. I would upgrade to at least a 2bar, and of course, you can calibrate the computer to be able to read that map sensor properly in your tuning program, just make sure you buy a well known brand from xenocron.com and usually it is supported automatically in the program by just selecting it off a drop down menu. For instance on ECTUNE....



the honda s200 chipping system should be exactly the same that is required to install any of the units from moates, unless its a zif (zero insertion force)socket, then it would need to be changed.

 

what the chip socket should look like

 

its the part that says 27256 btw

 

So i actually have a p28. whoops. not too worried tho its all the same in the end. But it does turn out i have a zif socket. hot damn almost made out like a bandit there. Now it looks like a have a chipped p28 for sale hah

 

You can use the ecu in your picture for your setup. You just turn off Vtec in the software.

 

isnt the p28 already a nonvtec ecu?

 

Nope. P28 is the SOHC Vtec ECU (D16Z6 engine).

 

oh good to know lol. wasnt planning on puttin this in before a tune anyways

 

well unfortunately you have the wrong chip socket for the demon, thats a ZIF socket and the demon wont mount to that properly, but i dont think it would be an issue for the ostritch, but dont quote me on that lol, also appears that the chip is installed backwards.

 

Dont worry about the chip, Id been playing with it and musta gotten it turned around. Ill have to do a little research on ectune and see whats up. and from the looks of it, the ostrich 2.0 will use the zif socket. havent found anything out about the demon tho

 

christ at xenocron could probably explain everything you need to get the ball rolling, i buy alot of stuff through them because they are close and have alot of good tech support
