Help BLM 150,INT 130+

[AsphaltAnihil8r]

Well I just installed my Delphi 50lbs injectors (from PTE) with a Testa Chip 93Oct and the blm are at 150 and int 130+ to 140 I did notice the IAC is high 50,,it used to be 12 with my 009's and a RA93 chip fuel psi is at 40psi line off,,could my IAC have stuck open due to not have been run for 2months ,thanks to Delphi for droping the ball with Racetronics,,any ideas please help

Go thru the idle min air and TPS setting procedure,
IF
your sure you don't have any vacuum leaks, and everything is assembled right.
I just saw a guy install a JT with 50s and when he got things right the idle and drivibility were right. He had a couple TINY vac leaks.

Well I reset the ECM Now the INT are at 128-134,the BLM starts at 128 then rises slowly over 3-4 minutes to 150,,the exhaust smells extremly rich

What should the translator Plus be set at ,,I think I have the 3.5in but how can I tell (what is the number on the 3.5),,, the car just started doing this ,ran fine with the 009 and the pig rich RA 93 chip,,,but this seems EVEN richer than that

My IAC finally came down to 40 area but seems it could come down more

I had a similar problem, except the exhaust definitely wasn't rich. Maybe you have an O2 sensor problem? In my case, it helped to set the MAF-Trans to "10% Rich" base setting.

What version is your translator?

Describe how your air filter is attached including the Air temp sensor.

Also, try twisting the MAF 90 degrees and check again.

Check for changes if you disconnect the cooling fan (turbulence issues)

Sounds like you have a 3" sensor.

Sounds like you have a 3" sensor but a 3.5" setting on your Translator. If so, MAF BASE position 3 or 4 will fix your rich fuel problem. Since you have a newer version of the Translator, you may have more options. Nonetheless, any are better than the wrong settings of 0, 1 or 2.

CAUTION!!! If your problem is due to an incorrect setting, the correct setting will reduce the amount of boost you can run.

Good luck.

Here's something to think about. I notice that if I reset the ECM and start the car and let it idle up to operating temps the BLM's will climb to some pretty high numbers. But take the car out and drive it around, and it all comes back to normal.

Most high BLM's as you originally described them are a result of a vacuum leak. Especially if you can't get them to come down after driving around.

 

[AsphaltAnihil8r]

Richard,,the car will not run for more the 3sec with the Tran+ set in the 3" positions ,,so I must have a 3.5MAF..

dave I understand about the Vacuum leak but,to charnge the injectors ,I just removed the vauum block and used new hose's,,but I did bend (pretty bad) the Vacuum line that is attached to the PCV (did not kink the PCV line) that darn bolt on the doghouse is a bit@h to get off without bending the line ..

I need to get an open end wrench to get the o2 sensor out ...tomorrow...


But Dave you are correct,today I did not take it for a ride ,,

Today
Reset ECM put trans+ in 3"mode did not run,,kept dieing
Shut off Reset ECM ,put trans + to 3.5 mode
car runs
BLM 128
INt128
Iac 90
temp 100
Semms at 160 the car ran rough,,the blue smoke out the tail pipes
BLM 140-150


Please help

 

[AsphaltAnihil8r]

Ok drove the car today after changing the o2 sensor ,that did not effect it ,still BLM of 148-150,,while light foot pedal going around 40mph the BLM are 133ish

Sprayed a who can of carb cleaner on all the vacuum hoses and no change in idle.even sprayed where the injectors fit into the intake...

Changed the 02 sensor ,,no differnce...

IAC is at 40 with the engine at 190°
INT is at 125-135
BLM start out at 128 then go up to 148-150 and stay this high..

My IAC used to be qt 10-13 with the 009's
Now IAC is at 40-60

I have New injectors 50lbs Delphi
With a Testa Chip that I bought here on the board in the fore sale section

Could the chip be the problem,as in not being set for my combo
TE61
THDP
Vigialnte 3000-3200 stall
THDP
Alki
PTE Front mount
50lbs--40 psi line off
hooker cat back
Trans + ,3.5 MAF sensor


thanks for any help

TURBOBOB,,The MAF set up has not been changed for over a year ,the KN filter is under the bumper /behind the headlight

Now when you say twist the MAF ,,do you meen that I have it in backwards,,the Arrow if facing the turbo inlet.

One other thing to think about is a substantial pre turbo exhaust leak. When my crossover pipe developed a large crack at the track one day. I sat there and watched the BLM's steadilly climb to max out in less than a minute when I got back to the pits. Exhaust leaks are like vacuum leaks, in that they will cause abnormally high BLM's also.

 

[TurboBob]

The late model MAFs are sensitive to turbulence, an Air Temp Sensor upstream of the MAF can cause 'wierd' blms.

That said, the Rev 4 and earlier translators were 'a little lean'.

50's can be 'a little lean' (what numbers are engraved on yours?)

Many 50 lb chips are know for being 'a little lean'

Add them all up and you get pegged BLM's.

I have a few things for you to try,

1, you can update your translator to the latest rev. It's a little richer

2, you can have Jim update you chip (which I'm sure he'd do for you)

3, have you tried the rich idle setting in the translator?


By turning the MAF I was refering to twisting it so the internal divider-wing is vertical and make sure any air temp sensor is not feeding turbulence into only one side of the MAF.

Also, there have been threads on the F-body boards that running the MAF backwards richens things a little....never tried it myself.....

Bob

(Could always run an Extender chip too....My blms are between 126 and 134...)

Please Confirm.

Just in case you do have a 3" sensor, there is one unfavorable characteristic to be aware of with the Translator Plus. With the timing feature utilized, the 3" sensor has poor idle manners compared to the 3.5" sensor. For street driving with 93 octane, bypassing the timing feature greatly improves street manners. You should have a bypass plug that will let you focus on what's causing your high BLM numbers.

To be sure of your sensor size, please measure the inside diameter of your sensor.

Now there's one I never heard of, or experienced

I've run both a 3" and presently a 3.5".

As I type the car is running in the garage with the Line on FP at 36psi the MAF "is" the 3.5,and I set the Translator to 1 which is rich for the 3.5 the Tans + has a Version of 4.0 the Injectors are
Black on the top and the other half(lower) is grey
flowed at 44.1( all say this)
the number that I see are in the black section of the injector#5161 17104487

Hope this info helps ...Dennis

Not Just Me.

TurboDave,

It's true. With timing feature utilized, 3" sensor caused a rougher idle than the 3.5" sensor. Could be that newer versions of the Translator Plus don't have this problem but it was found to be true on my car and two others. Extender chip did help but in all cases, street manners were further improved by bypassing the timing feature or by switching to a 3.5" sensor. Curiously, cam and injector size were a non-issue. One car has 009's with a stock cam, another has 009's and a 214 cam and mine has 55's and at that time a 218 cam. Wish it wasn't true because it was a pain to figure out the problem.

Partial Update::

I did set the Trans + to 3.5 Rich ad raised the Fp to 37# line on .My BLM have come down to 137 are from 145-150
I could not find a new AC Delco PCV at the parts store so I still have the 2 yr old PCV in place with the Check valve..

At this point if I lower the FP to lower my o2 at wot ,wont my BLM go back up,,, Im affraid to touch anything since I have the BLM lower

Told ya!

Did the exhaust smoke go away?

Yes smoke is all gone,,,that was enough to kill a person,,Peee UUUU,,my clothes stink....

But thanks everyone

Good deal. Follow the rest of Turbo Bob's tips and everything should work out.
