da connected but no data

**EagleMark** · 11-20-2012

I hate to tell you this... your getting data! Time for gas and start the engine!

Watch data if you want while warming up but try to start data log when engine is warm, at least 160 degrees and up. Record a log of idle and driving and post it up, we can see where your at!

When you get the chip buring stuff read your chip and we will see if there was anything there to help your engine.

i can not veiw any data on the screen when datalogging or when datalog playback but it shows that it is running but there is nothing on the screen .I have tried the different items show data,show dash,show monitors.any suggestions?

**EagleMark** · 11-20-2012

Look at the bottom for Item lists, Dash, Monitors after you open them. They may be there and need to grab them and strech them up. Put your mouse near top of header that says Item list or? until it turns to a double arrow, then click and drag up.

Or go to View and make sure Floating Utility tabs is not checked. If checked they could be behind TP, minimize and see if they are behind?

Mark that was it,floating tabs was checked and all the data was behind the screen.on my way home to try some data logging.

**mdj** · 11-21-2012

looks like I may need a heated o2 or its getting coverd in suet from running rich.most of the other stuff im not sure of,vacume looks pretty low and some of the timing logs seem high,I dont know how to reead much on fuel without the blm comming on.injector duty cycle seems crazy high .

**EagleMark** · 11-21-2012

Yeah ya gotta couple issues...

Spark advance and BPW/Injector duty cycle will not show in data until you do a hack to bin and burn a new chip.

Your Open Loop so BLM won't help, you also have an DTC/Error code 13 which is 02 sensor so have to find out what's wrong there. Clear codes because you have a 33 that will probably not come back.

Also IAC counts are 145 and never move but no DTC so may be wire or plug?

While your getting these worked out you should also know your fuel pressure! You got a lot of work done to this motor right? No WOT high RPM until you get this stuff dailed in! And look at timing table etc... to see what is going on in bin.

Built a 357 ci..500 lift on int. and .ex 218 and 228 dur. at .050 112 ls 4 deg. built in adv.stock heads ,flattop pist.roller cam and roller rockers ,ground down tbi body.adj fpr,cop car injectors running 14 lbs fuel press.

This is in a rock crawler that I drive on the street some.I am looking at the moats osterich2 and the burn2 with the prom adaptor .we have 4 tbi vehicles so I'm not looking at ebl.does this appear to be a good rout or am I missing something.I guess I'm at a stopping point until I get these.I have a stock chip from a 7747 might play with it.

**mdj** · 11-24-2012

Mark if you get a chance to look at this great,if not dont worry.I have to start researching what comes next and what some of the terms in the log mean. o2 prolem taken care of,iac is working at the end of log was running low on fuel so dont pay attention to were it went way lean I burned thru 10 gallons in a hurry.If you get tired of fooling with this be sure to let me know I dont want to over stay my welcome.

**EagleMark** · 11-24-2012

Your welcome to come and learn. You really have to have time and desire to do this! It takes a lot of time. Your not going to click few buttons and be done. Plus this motor is not close to stock.

What's the estimated HP? Have you calculated the fuel pressure needed to support this with your injectors? Calculated BPW?

You still got some issues and with what your telling me of fuel consumpsion I think you should stop driving and change your oil! Is this a new motor? If so stop driving and change the oil.

Your data log shows pretty good right at history avarage? Wrong! The highs and lows are so far apart the average came up in ball park. You also have an Error 45 O2 Sensor Rich. I think your O2 sensor is soaked with fuel and well now soot and it's lying to you.

Hows it idle? You don't have VSS so I don't know when it's idling, neither does the ECM...

Your also in Park the whole time? Do you have the Park Neutral wire? Is it grounded? What transmission?

**mdj** · 11-24-2012

Tranny. Th350 built.
Park/neutral is grounded,I could fabricate a switch on the b&m shifter if absolute needed.
No vss. This rig is usually going a few mph.although tire speed sometimes jumps up,once again I can look into a vss for a np205 transfer case if absolute needed.
I have run my injector size and for full engine potential I would need 22# fp to go with 65# injectors.
I think small throttle body will hurt more than anything,that and low flow heads and intake.
Will check oil and plugs.
Idle is ok not great,kind of comes and goes.never will completely die but can get low before it catches back on.
I think other questions are answered in pm.

**EagleMark** · 11-24-2012

Disconnect the Pk/Neutral wire and it will idle better. IAC control is limited in Park.

VSS is always an improvement but not necessary.

The smaller TB and low flow heads will be an advantage for low RPM torque for rock crawling and driving a big tire truck on street, will take away a little WOT high RPM.

What headers? Long tube?

**mdj** · 11-26-2012

Block hugger shorty headers from a fitment issue .rig is pretty light around 3800 pounds.Things went worse today started running even richer at idle and o2 rich code.changed out o2 went thru and checked wiring again .checked any leaks at injector,checked fp again(13.5)when revved up a little it staightens out to where the blm hang around 128 and the 02 jumps back and forth.At idle the 02 will stay in the 800 and 900 range.This is a newly built engine to answer a earlier question .low end torq is what I'm after.rotating asymbly was already togather when I got the engine or I would have went with a milder cam however thi is a custom Lunati grind that was said to be max cam for a tbi.

**EagleMark** · 11-26-2012

When you build and engine like that you need to build at least a starter chip before you start it just to break in cam. All the issues your having right now are becasue of the cam. Look at idle MAP! It's way lower then stock. Other then diagnostics and very short drives you should be tuning. Unless you have a mechanical issue it's not going to get better till you tune it.

Also need to check for vacuum leaks.

**mdj** · 11-26-2012

Its a roller cam dosnt really need a break in but I get your point.Iam not driving at all except for tunning purpose but things are changing in the computer all the time.I will order burn 2 tomorrow but really dont know where to begin on tune.i know i will set my fuel delivery for egine size but its already set for a 350.I am asuming that the bin file is what will be on this chip when i read it and a can load it as my bin file at start changing settings on it then burn it back to the eeprom.running down the road at constant idle it appears to be fair on blm.idle i would guess would be the first item to tackle which i need to pull a lot of fuel from.base timming is 5 so i will need to set that on the eeprom tune.other than this its going to be a shot in the dark.there will be a few more day to read before things arrive.
