problems Tuning. any idea's?

[FastFwd]

guys needs some help. my car is at the tuners at the moment. just got my turbo kit on and they installed my vafc 2. there having problems with tuning it because apparently my ecu isnt doin what it should. its counteracting with the tuning on the Vafc. and every time you try and put the fuel up on the vafc it will go down or up too much and with either lean out or become to rich. hes going threw all the Sensors and the wiring first then gonna try and replace the ECU to see if thats the problem. anyone got any idea's

[pg_vtec]

what ECU do u have?? is it factory or aftermarket..

If its aftermarket depending on what type u dont need your VAFC as it will have these functions in it..

and if its Factory and u have a turbo set-up i think u should sell the VAFC and buy a aftermarket ECU...

[pornstar]

Fastfwd, vafc needs to be run like a "hack" for it to work with boost. Go back to the tuner and ask if there is a map bypass of some sort, if there isnt, the stock honda ecu will be throwing the CEL and going into limp mode.

[saxman]

the problem is you're trying to tune a turbo with a vafc(yes, I know it's possible, but it's a horrible option). Sell it, and get some real engine management.

[FastFwd]

ohh i deffinatly wanna get a power FC or an aftermarket management system like autronics or motec but right now i have spent to much on my car - i want it to run with what i have with minimal boost then ill upgrade after that. ive done a twin carb d series swap to a b16a2 then chucked on the t04e garret turbo with cam gears, pully kit, 3inch mandrel bend turbo back exhaust, fuel pressure reg, bigger fuel pump and a few other mods.

Porn star: what did you meen by it chucking it into limp mode?

they place thats doin my car put my engine in - and its still under warranty so if it was stuffed from the beggining i think there going to fix it. ever since i got my engine in there it was running rich on the bottom end.

i know its going to suck to tune the vafc thats why im not doin it. but for the next 6 months i just want it to run on that until i get a autronics or power FC.

[pornstar]

limp mode, when the stock ecu sees boost

do urself a big favour and get onto the autronic or power FC now. Unless you want to continue hurting ur engine as it is.

[saxman]

pull off the fuel regulator and fuel pump, buy some injectors, and use uberdata until you have the money for a power fc... far far superior option, and won't cost you much of anything... probably less money than the dyno tuning you're using to tune the vafc

[FastFwd]

pornstar i wish i had a money tree. i've spent over 15 000 on my engine in the last 6 months.

saxman: why you reckon pull of the reg and fuel pump. i might be getting some injectors. whats uberdata - is it a premapped ecu?

[pornstar]

uberdata is a freeware, it works the same as hondata, it plugs a chip into ur stock ecu. Basically if ur obd1 or if u use a conversion harness from obd2-1 for obd2 cars witha socketed obd1 ecu, u can make them tuneable with uberdata

Im guessing saxman said to remove the pump and reg, so that it can be used with less comlpications as more basemaps would be around to support standard pump and reg tunes (correct me if im wrong saxman)

[saxman]

the fuel pump may be needed... just remembered you were running a little carb d16 before, but for the fuel regulator, the stock one works perfectly fine. At 6-8 psi, there's absolutely no reason to be messing with the fuel pressure.

Uberdata is an ecu software, just like hondata, etc... only it's free.

[saxman]

actually, I said it because he's complaining about not having enough money to pay for the most important part of the turbo set up, when he has these extra parts, that are offering absolutely no gain what so ever, sitting there. Selling them and using the perfectly capable stock counter parts would pay for the better ecu hardware, and make for a FAR better engine set up.

Everything that you need to know about using the safc to add fuel is in this thread here

http://www.honda-tech.com/zerothread?id=137901

It will not control the ignition timing of your engine, so expect to see about 30+ degrees of ignition timing at peak. Most people retard the timing at the dizzy and have a trade off of poorer performance down low due to the reduced timing.

You could also find that the car will be faster using this method then using an ecu to control the engine, as you will be running higher ignition timing. Let it be known though, you are putting the engine in dangor using this method.

[FastFwd]

saxman: i didnt do a conversion - i did a complete swap. changed the fuel tank, fuel lines, ECU, Engine, gear box - Pretty much everything including axels and all. so its pretty much a b16a2 93 civic now. only reason i got a bigger fuel pump was for more performance mods i was putting on in the future which is now.

how do i remap the ecu with hondata or uberdata. when do i get it from may i ask?

[saxman]

you can get the software for uber from pgmfi.org, along with all the needed info to remap

LVnit: i have toda adjustable cam gears?

[LVNIT]

Cam gears are going to adjust the intake and exhaust side of things

You use the distributer to retard the timing, which helps the engine out a bit with the peak timing you can get from using the safc.

With uberdata you are also going to need a chip burner which will cost about AU$140

[FastFwd]

has anyone in australia done a hondata or uberdata setup. if so can you let me know off a place or site or what exactly i should do if i could do it myself?

and if tune it this way can i still use my apexi vafc 2?

[Weq]

have u got 440cc injectors? U need this to run the afc hack. Stock fuel pump and regulator is fine. you dont need ANY map bypass for the AFC hack. Retard ur timing at the dizzy a few deg's to couteract the ignition advance. That said, the closwer to 10psi u run, the more ur timing will be stock.

You guys are all crazy. There is no way this guy is going to be able to get a uberdata setup going. Stop throwing ill directed (this guy didnt swap his motor. he cheuqebooked it) advice around and deal with the problem at hand.

Hondata is sold locally, checkout hondata.com.au

[yourfather]

stuff the V-AFC2. better off you get rid of it somehow. Its a waste of your time.

[Beastcivic]

hey dude,

who did the conversion? Im in perth too, blue ek turbo d16y4. You have to cut some wires on your standard ecu otherwise your car won't run that good, but Im sure the place that did the work knew this and has already done it. Mine was doing all kinds of funny sh*t when my std computer was still in, like would not idle, shaking at 2000rpm etc etc.

Agree, besides not many people are going to be interested in tuning the program and then having to search through the Uberdata forum to fix some of the things that wont work.

hey im in perth (north of the river, joondalup area) i got a white 93 hatch. who setup/tuned your vafc for the turbo?

[Beastcivic]

Im freo area, I did my whole setup, but the tuning, ovaboost did it, I have microwreck by the way. I had major problems getting mine too run at first, then i ripped out my std comp and it ran fine. I put the std comp back in now, simply because It controlled pcs valve, vss sensor, etc etc, But I had to cut alot of wires because for an unknown reason, when the std comp was in, it made it run hell rich. Who does your work?

Gararge R/Formaz are doin my work - they did my convesion and pretty much everything else. i put the turbo kit in.

[FastFwd]

guys i got an update from gararge R with whats going on. they have told me that its not a problem with the Vafc tuning to the ECU its an actuall problem with the ECU itself. its not auto programing itself like it usually would. when there putting it on the dyno even at 3000RPM it starts to lean out and the turbo hasnt even spooled up yet, they said even at 3000RPM in 3rd gear at 80k's its dangerously lean. so when they go to tune the Vafc to the ECU, the ECU isnt doing what it should be doing so the vafc is making it go wako.

could it be a Sensor?

[ProECU]

Read out your ECU Codes to find if its a sensor.

[LVNIT]

What are you doing to stop the ECU reading boost? How is the vafc connected to the ECU?

[FastFwd]

not auto program, i meen its not doing what it should be doin. as if it has one fuel map and its staying like that threwout the RPMS and not going up or down when you put the RPM's up

pro-ecu: what did you meen by that. sorry im a bit of a newbie...

i dont know? its wired up like it should be via the wiring diagram? is there different ways?

[FastFwd]

I'll tell you the problem but your not gonna like it,

Garage R is the problem, They are the dodgiest place in history, My mates lancer has is still stuffed, If they built your motor, i suggest you sell it fast. Most of there motors don't last 5000km or initial start-up. I mean the owner is just a back-yardy guy who probably hasn't ever worked on a car.

:thumbdwn: GarageR :thumbdwn:

Good choice of motor though, b16a, best motor out there

ive driven my car over 5000km and its still crusin? had a few problems with a few things at the start but now its all good just took a while to go threw all the little things that needed to be fixed when swapping the engines

trust me ill never sell my car. spent way way to much money and way to many years and hard work into it, to just sell it to some young P plater to thrash

[FastFwd]

i know they dont have all the resourses other shops do but they have been decent to me.....

I disagree. B16B thats been stroked to 1.8 litres is better.

dodgy??? ok, backyardy???? ok, if thats what you think then cool I'll cross you off my christmas list,

but just so you know we have only ever done 2 lancers and both of them turned out awsome and your more than welcome to speak with the owners to see what they have to say,

and yeah I just started a bussiness with my partner who worked for Honda North for 7 yrs and was the only one certified to work on NSX in Perth at the time and we have also just bought another workshop with 700 sqm of space and three hoist and a dyno, and thats all because I know nothing and I just like losing money?? c;mon you cant be that thick?? can you ??

and as for the FAT jokes you;ve really hurt me,and i think im gonna cry! I cant help it if it is a thyroid condition! and I Know who you are so we will be having words next week to get through this together so we can love again and stop the hurting inside!

till then buddy stay cool :wave:
