in boost i run around 11 to 1 and 10 to 1, can that rob me alot of power? its a d16 fully built with a t3 48, 62 and i cant even chirp the tires, i have uber and i wideband but i dont have the wideband hooked up to the ecu. can someone explain how to hook up the wideband to the ecu so i can start datalogging?
thanks

 

of course that will rob you of power . so will timing , whats your timing set at?

 

please list your setup!

 

d16
scat rods
9.1 to 1 pistons
golden eagle block guard
built and blue printed
t3 48 62
big ol intercooler
dsm 450
uber
set up for datalogging
plx 300

 

whats your timing set at , what chip are you using on uberdata

 

didnt the wb02 come with instructions? go on PLXs website or call them and find out. or sell it to me.

 

timing on the car is stock, ign. timing is retarded .9 per pound i believe

what do you mean?

How much boost are you running?

Lets say you were running 15psi, your timing would 2 low. Try a lower setting of retard/pound, around .75 instead of .9

Running rich will rob power, but not much at all.

 

right now it is set at 8 psi


can anyone explain where the white and grey wires need to go?

 

Id rather run rich then lean. Gives you more room to tune safely IMO.

 

running 10:1-13:1 wont effect your power as much as timming....

when tuning standalones we worry about getting the timming set correctally and air/fuel....is down the list....as long as you are within a safe a/f limit...you should not worry so much...and look to your total timming under boost...thats where power is made and lost...not saying a/f wont take or give to you...but timming is where the power is bro.....if you run a knock sensor then you may be running to rich, and creating fantom knock...and if you are running a knock sensor it will pull timming and you will lose alot of power from that

good luck with your project

well i got a egt and the temp seems real good at the timing i have it at, 800 at idle, 1400 cruising, and 1500 at boost
should i retard it to .75 instead of .9 per pound?

 

1500 is fine...but why do you retartd timming for boost????
I run 22-24 degrees total timming under boost...if you are not detonationing under boost there is no reason to pull timming...it only robs you of power and you will see higer egt's the more timmign you pull

well arent you retarding under boost too? i thought normal timing was 16 degrees?
i have the distributor set at 16 degrees. are you saying i shouldnt retard it in uberdata at all?

 

the grey wire goes to your ecu in the case your WB02 sensor replaces your factory narrowband, so that the car will run right. the white wire goes to your display, im guessing you dont have one.

Yup. Theres prolly a 10-20hp difference between 10:1 and 12:1 on most setups.

However, timing makes a huge difference.

 

so maybe i should retard my timing .75 instead of .9 per pound?

Yea.................YYYEEEEAAAA!!!!!!!

 

what is a dangerous egt temp in boost?

 

**** on only 8 psi, i personally would go with .5/ psi
If your running 93 octane you will be ok..

 

You need to look on the uberdata forums to setup your datalogging but I'll give you the cliff notes on it.

1. Setup your ecu for datalogging, this requires converting the TTL signal, most people use a hacked radio shack Nokia cable and run it USB, this step requires soldering into your ECUs CN port.

2. Re-Compile your rom from scratch with an Uberdata version that supports datalogging. (Everything 1.66 on I believe), set your rom for Disable O2 heater circuit and closed loop disable.

3. Find your O2 signal wire on your ecu, temporarily cut it and splice in your a wideband output signal, not narrowband simulation.

4. Open up your rom, plug in the USB cord from your ecu, goto Datalogging.

thanks
so my timing is too retarded (no pun intended) if i lower it, will my egt raise significantly?

 

Running more timing will lower your egts.

 

yeah thats why i want to lower it, lowering will raise egts, i just need to know what is safe

 

every motor is going to react to timing differently. the only real way to tell is to put it on a dyno and see what kind of power differences you are getting while adjusting the timing values. a safe way to start is about .75 per lb of boost and work from there
