My friend finally got his turbo setup up and running on his hatch. He is running uberdata and has some dsm blue tops that we were trying to put in his car. We have spend 2 days trying to get those damn 450's to work in his car, but we have had no luck. His car will start and idle fine, but whenever he got on the gas it would studder like it was missing or something. We thought we had the resistor box wired wrong so we rewired it over and over again. We even bought a continuity checker and a multimeter to make sure all the connections were fine. We also tried using the uberdata chip from my car which works flawlessly with my dsm 450's. Still it wouldn't work so we just threw the 240's back in and burned a map with the fuel values scaled back up. It runs perfect with the 240's. Its really smooth, but he hasn't gotten on the gas yet because were afraid to boost with those stock injectors. His wastegate spring is at 7psi. Do you think he will be safe only boosting at 7psi with the stock injectors until he can buy some rc 440's?

 

160whp worth of psi.

 

I wouldn't try it.

If you're going to use the stock injectors, it's "safer" to run it with an FMU temporarily.

 

well he does have an fmu and we tried that, but the car kept throwing codes even with a couple check valves. It runs great with uberdata though.

 

take the 4 wires that you have going to the black and wire them up to the single red wire from the resistor box and then take those 4 wires and put them to the black ones and your problems will be solved

 

looking for an update, hope that works.

 

are you using uberdata version 1.7? because I had huge problems running them correctly with my ls teg. I have a wideband and it would lean out and stuff. To fix that they said to open a GSR map and import the ls bin. Then disable vtec and change the rev limit lower. That and making sure you disable closed loop and everything worked fine for me. I thought too for the longest time it was the injectors. Check your plugs. If they all look the same then they all work the same meaning the injectors are fine. If your resistor box has a problem you probably would have already fried your ecu so that it not it.

IMO it's uberdata. Try different versions too. That could help. PM me if you want to talk about it. I spent hella time on this problem so I'm sure we can figure somethin out

we have it wired up like that. The wiring is not the problem. We have checked it over and over.

also its not uberdata. Uberdata runs perfectly on his car with the fuel values scaled for 240cc injectors. I even tried taking the uberdata chip from my car and putting it in his car because my chip is setup for 450's. It still didn't work, and I know that chip is fine because it runs my car flawlessly. Oh and we also did end up blowing the ecu fuse at one point. We fixed that though.

 

240/10.5= 22.8pound injectors
22.8 X 4(#of cyclinder) X.85(duty cycle) /.5 = 155hp
about 6 to 8psi

 

Don't do it.

Thats all fine and dandy but at higher rpm's the car doesen't have the time to inject the proper amount of fuel with the smaller injectors. Just build an uberdata basemap with a gsr with stock injectors. Set the fuel multiplier to 120%. Click on the duty cycle map in the uberdata editor and you'll see how ugly it really is!

EDIT:

At 5 psi and 7000rpm's I'm getting a duty cycle of 130%!!!!!!!! So basically you will run lean and blow your motor LOL.

 

I'm boosting with 240's and a greddy bluebox on a homemade setup using a IHI RHB5 VF and hit .86 bar and never had any problems with bogging or stuttering, running lean or anything. I'm must have some super 240's or something?

would you just try it, i swore up and down to phiz i had it wired right, but as soon as i switched it around it idled and ran perfect w/o any boggin, stuttering, or detonation up in the top end.......

so just switch em one time really quick

 

yea I noticed how high the duty cycle is with the 240's. I told him I didn't trust it either. As far as the wiring goes we wired it just like ladysman said in his thread on it. We even tried wiring it like I did on my obd2 car which apparantely is different than obd1.

 

Whats your fuel presssure under boost sucker. Were talking uberdata with stock FPR. If you can boost .86 bar on 240's and not go lean on an unmodified stock FPR then your car doesen't make **** for power.

He said hes runnign the greddy blue box..

now would it be possible to just throw an fmu in there with uberdata? I'm guessing i'd have to modify all the boost fuel tables to have the same values as the last column of vacuum so i wouldn't run too rich right? He tried using an fmu for a day or two until we tried putting in his new injectors and the car ran like ***. It kept throwing cel's and going into limp mode even with two check valves thrown in there. I know uberdata would be able to eliminate the check valve problem because I can give boost tables some values.

again...its not my car . We were just wondering about boosting on it temporarily until he can get some rc's.


haha when did we say that? The blue box sucks man We are using uberdata.</TD></TR></TABLE>

Danl wasn't reffering to you...read

 

i'm stupid

 

bump cause Im the guy needing help.

Right now I am boosting 5-6psi but I havent pushed it past 5k rpms and 1/4 throttle and only once did I take it to 5grand normally its 4grand and light throttle.

also what if the injectors are not seated in the manifold all the way down, the sit out a bit from the seals but no leaks.

 

bump

 

anyone else?

Bingo, there's your quick fix until you get things sorted out. Keep fuel values static, use Uberdata to retard ignition, and everything's fine.

 

how much boost could I run then? and should I floor it, cause I have been boostin for 3 days and only giving it 1/4 throttle and shifting at 5k rpms
