** CHIPPED ECU TUNING JOURNAL **

[Accord R33]

hey midnite im free tonight so im gonna try and play with the map and see if i can get it a little richer at high vaccume. i should have an answer by tonight.

theone - you might have to add fuel in the non-boost portions of the map. the boost columns are pretty rich due to MRXs t3/t4, I dont know what turbo your using though. if its a t3/t4 or bigger you may have to add a little bit.

its gonna have to be tunned to your car specificly anyway so you will be able to figure out what needs to be done during the tunning process

thanks...

R33 answered it pretty well...i'll just add this...only the wideband can answer that question.

cool man, I'll be keeping an eye out for that basemap. I haven't actually picked the head up yet, so i'm not really sweatin it.

p.s. thanks for the replies, didn't mean to jack the thread.

whoops, that was me using my friends name peace

[theone]

so any new updates, hows everything coming along???

[MRX]

programmer still won't work. I have to wait till tomorrow (if i even have enough money) to probably order a new one. Anyone wanna help a brotha out paypal me a couple bucks...playatastik@aol.com. Besides that the car is running really good on this map, no complaints here...what about u r33? How's gas mileage?

[Accord R33]

ill send you some money for the ECU you sent me.

gas millage is ok, i think when i lean it out to match my 14b it will be a lot better.

[MRX]

lemme rephrase that...how is NON-boosted gas mileage lol? Or are you extremely confident and can't stay out of boost?

[Accord R33]

stay out of boost? hahahahha yah right.

its kinda hard not to boost when you start spooling @ 2500 RPMs

[MRX]

any luck fixing the high vac problem, R33?

[gdout90accord]

hey that 14b turbo start spoolin at 2500? daymm i thot it start around 3200 or 3500

[MRX]

you'll never guess what info i found on hmt...

per xenocron - When you let off the gas, the Throttle plate shuts closed. When the ECU sees the Throttle plate closed and the engine is higher than 1100 RPMs, it should shut off the injectors and use engine compression to slow the vehicle.

I say should because I have observed the injectors staying on at random times with various versions of the OBD0 code...sometimes it does it right, sometimes it doesnt.

Obviously, when the injectors shut off...your Wideband will read lean...mine tells me 20.9% Oxygen, which is what Air is.

green91 - Hmm, i think i will try scaling the fuel down quite a bit then. At idle i seem to be at about -18 vacuum.. but when im going down the road and let off the gas, its closer to -30.


Very interesting huh? I'm gonna ask the ppl on hmt that have civics and tegs with wb's to gimme some feedback on what they see when they let off the throttle. If this isn't such the problem i thought it was then the map is about 90-95% complete

mines looks like it starts boost at 3000-3200

i boost yesterday just to make sure everything was str8.
rev it to 3000 while in first, let off the clutch, boost gauge read 5psi and climbing, then i let off it, didnt want to f up anything sense i dont have everything yet.
seeing that made my day

still waiting like a shark for the base maps, ready to start trying it out on tuning a n/a f22
