Anyone have some tuned B18C turbo maps?

 

me too... share the knowledge!

 

They are built into ROM Editor 2.5 as supplied with every stage 4 system.

 

Great! For an extra $500+ you can have a running turboed Honda

 

fock that.. i rather get it tuned.

 

I had my P72 reprogrammed to have its rev limiter removed, speed limiter removed, timing retard and injector maps pushed further to end of their maps. Will I have to get ECU reprogrammed back to stock when I add hondata or will hondata fix it?

 

Correct me if I am wrong but all you had done was add a chip to your ECU. This would be actually easier for Hondata to install their stuff.

 

Let me clarify things. The dealer from which you purchased your system should easily be able to provide you with GSR turbo base maps to get you started.

1 thanks and I can help you out to. A hondata retail shop close to me (which will remain anonymous) says the basemap provided by Doug at Hondata will blow your motor up. Their basemap is to get you to the tuner and thats it, basically.
Well actually blow my motor up. Dougs basemap is set to 14 psi.

tuning is a bitch. thats probably the most expensive part of the whole idea of getting a standalone. you pay someone over $150+ just to tune it the first hour here in cali. it could take as long as 3 hours.

 

Yes but I am having some trouble with them. I have 50psi atmospheric fuel pressure and RC 550cc injectors.

With the turbo map it wants to make my injector multiplier .434. The car will not even idle with .434, I have to turn it up to .7 to even get it to idle decent.

I don't know what the problem is.

 

I was having idle problems with 550s also. I ended up raising the idle speed to 1100 and turning down the iac duty cycle a little. Then i messed with the iac screw on the tb...now it idles perfect at 900 rpm. Just try messing around with those settings and you'll eventually get it to work. My multiplier is at .51 and 43 psi atmostpheric.

 

I'll have to mess with it. But if I leave it at anything below .6 I can't get it to do any closed loop oscillation at idle... it just reads full lean all the time.

at .434 it REALLY hesitated driving around town (when I could keep it running). Only ran OK in boost but made lean-sounding clicking noises under acceleration. Sounded like a diesel...

Seems to me that hondata should be able to make the car idle perfectly at 750rpm with no funny idle on 550cc injectors...

 

this is exactly why i rather have it installed at a dyno shop with experienced Hondata technicians.

 

Guys, am i going to have major difficulty's tuning my 650 RC injectors with the stage 4b?

 

Dustin.
The multipliers are just ballpark calculators. Don't think you will get things dead on with that. You will need to wideband tune it after that to get the mixture right.
Its a bit of a pain but you should get perfect idle. Screw the closed loop. It runs like crap in closed loop with turbo. Run open loop and just tune it correctly and you should be golden!

 

Yea, definitely run open loop...I also had a hesitation problem. But i changed to open loop and fixed the idle problem and the hesitation is gone. It does feel a little strange in the mornings before the car is warmed up, but it goes away within 2-3 minutes.

 

dustin,
you get a stage 4?
email me your ROM program so I can see what you are doing. I'll compare to mine. I got my wideband built and running. I'm going to spend a day getting a really good wideband tuning on my car this weekend. It seems logical to do this and spend some time with this since doing this on the dyno never will equate with what goes on while driving on the road. The dyno will only fine tune this and allow fine tuning of the timing maps too.

By the way,
what happened with the forum? I can't see where everyone is from anymore.

Well, my car ran fine on the stock ECU in closed loop

And the map I am using is just the "94 GSR Turbo Map" built into Rom Editor. All I have changed is the injector multiplier and rev limits. I played with ignition advance around idle but it did not seem to affect much.

When I was driving with this map at .434, it ran fine open loop. Closed loop /did/ suck. Once I got on the throttle enough to get it out of closed loop it ran fine.

Is there something wrong with the Hondata closed loop code? The lo fuel numbers are identical to a stock GSR map....

I'm not even talking about closed loop in boost or anything in boost... my car just /does not work right/ driving around town until I can get it out of closed loop. If I turn the fuel up with the multiplier, it seems to run OK. I cannot imagine that my motor just "needs" more fuel than every other motor on the planet.

p72 ecu btw

 

man thats hardcore, what if you arent paying attention or your off your game and you miss a gear.... ouchie i dont wanna be there.

 

this is what scares me about the hondata, everyone says its a great system but it seems you have to iron out the bugs, why would it be so hard for hondata to share some real close base maps,thus only needing minor fine tuning? could it be they want to make $$$ for the tuners? reason id like a good starting base map is cause i live far from the closest tuner...with all the people running the hondata i dont see it being a problem having some real good maps floating around that we could share.

 

I don't think there's anything wrong with the closed loop code. It works fine on my car, with 440cc injectors. What's wrong with changing your multiplier to .7 and driving that way? or is it then ridiculously rich when not under idle?

What numbers did you punch in to determine the .434 multiplier?

 

the base map is close but every car is different especially with aftermarket mods.

The closed loop definitely leaned out the rich settings I had but cruising at highway speeds at low throttle and at low speeds around town, seemed to choke at times.

 

The thing that is wrong with that is that I /should not have to/. It means there is a problem somewhere.

.434 came from going from 240cc injectors to 550cc injectors.
