Installing EBL P4 for SBC TURBO PROJECT

Installing EBL P4 for SBC TURBO PROJECT
I purchased an EBL P4 with embedded lockers for my SBC TURBO PROJECT (thread can be found on Power Adders).
I’ve done a fair bit of reading but I think this swap is more than I was expecting… 🤣
I added the MAP sensor pulling 5v from the TPS
Deleted the MAF Sensor and unplugged the MAF relays.
I pulled the connectors out of my 165 ECM so that I could install the comm port only to find the whole connector already full…
This leads me to believe that I’ll be removing and moving a fair bit right?
I follow directions fairly well
who wants to help me with this…
I do have chip burning, and tuning experience

Re: Installing EBL P4 for SBC TURBO PROJECT
Going from a '89 ('85 - '89) MAF setup to an EBL P4 requires a total re-pin of the ECM harness connectors. Need to also add the third connector. The eecis.udel.edu re-pin guide is correct for a '7165 to '7730. But not entirely correct for the P4 ECM.
Send me an email and I'll forward the '7165 to EBL P4 re-pin guide.

Re: Installing EBL P4 for SBC TURBO PROJECT
I love this place!!!
What an unbelievable car community!!!
None of this could be possible without the collective knowledge of everyone here…!
I’m gonna keep pushing forward on this project with help from “my friends”…
I’ll keep posting in the power adders page unless it’s totally a ECU dependant question/update.

Sammy, you cannot make changes to the Bins that the system comes with. Open up Bin 3005 as you already did, but before you even get started, click on File > Save Bin As. then rename it and save it in a different folder elsewhere. Once you "save bin as", you will see the name of the Bin on the top left change from Bin 3005 to the new one you named, then you can start making changes to it while saving your work and changes to it...

Re: Installing EBL P4 for SBC TURBO PROJECT
Also, close both TunerPro and the WUD. Right click on the desktop shortcut for each (separately), and select the properties dialog. Under the compatibility tab should be a line that states to run this program as an administrator.
Click/check that line and OK out to close the dialog.
The issue with not being able to write the log file is a permissions issue. Laptop security too tight.

Re: Installing EBL P4 for SBC TURBO PROJECT
We’ll I started the car for a min or so….
wideband said 10:1 !!!
I think I fouled the plugs bad because it won’t start anymore…
looking back at the tune I noticed that my WUD said cAFR 3.8!!!
and boost of 12!!! (believe me I never got into boost….)
I initially used the 3005 bin changed the MAP to 2 bar, the injectors to 80lbs set base timing to 6*
Somethings not right…
I did find the crank AFR vs temp and changed it to 10… but I think to little to late…
any insights?

Re: Installing EBL P4 for SBC TURBO PROJECT
For sure the readings don't make sense. Doesn't take much to foul plugs with those big injectors, stock up. I have EBL Flash2 so might be different. Some simple stuff before the experts chime in: There's a BPC calc in the EBL Utility for mine, don't know about P4 did you do that? Also timing on the distributor (EST disconnected) set at at 6 degrees too?
Oh yeah, and don't forget to save and flash it in as a new BIN so you keep track of the changes

Re: Installing EBL P4 for SBC TURBO PROJECT
At key-on, engine-off on a cold engine, it is typical to get a low commanded AFR as you will be cranking the engine over to start. I see that the ECM is telling the WUD that a 2-bar MAP is installed.
But the WUD is also showing 12 psi of boost (should have stopped there). Either the MAP sensor is bad or it is wired incorrectly. Need to fix this.
Also, use the WUD diagnostic display to check the sensor values. This display will show the actual raw sensor values. Not the default values when there is a sensor malfunction. For a 2-bar MAP at sea level it should be at about 2.4 volts, 104 KPa.

Re: Installing EBL P4 for SBC TURBO PROJECT
Thanks gentlemen….
I can admit I was way to enthusiastic 🤣…
In hindsight I shoulda noticed the boost reading and stopped short of trying to fire it up.
The timing was set with the EST wire disconnected.
I probably half fouled them with a crappy Distributor Ignition control module ….. grrrr
Unfortunately, Winter is coming fast here.

Re: Installing EBL P4 for SBC TURBO PROJECT
Check the pin location on the MAP sensor itself in correlation with your connector's wires. I remember when I was posting on the Turbo Buick boards, a few of the guys were complaining of how some of the aftermarket MAP sensors they were getting on ebay needed to be inverted because their assembly produced the pin locations backwards...

Re: Installing EBL P4 for SBC TURBO PROJECT
Speaking of pin locations, be sure to confirm;
D2 Map Ground (from ECM) > Map Sensor Pin A
C11 Map Signal (from ECM) > Map Sensor Pin B
C14 +5v Reference (from ECM) > Map/TPS Sensor(s) Pin C
- Rob
Edit: I just realized that although you started with a MAF harness, you went with the P4 and rewired the entire harness. So disregard the pin locations I wrote above, that is for the Flash system. So yes, confirm the pin locations on the MAP sensor first, make sure it aligns and matches with your wiring...

Those purchasing new 3 bar map sensors from AC Delco part numbers 213-1562 or GM 12223861 the sensor is wired internally different than the original TTA 3 bar.
The correction involves swapping the power and ground terminals to it. Whereas old sensor wiring is
A= 5v
B=signal
C=ground
New wiring for 12223861 or 213-1562
A=ground
B=signal
C= 5v

Re: Installing EBL P4 for SBC TURBO PROJECT
Bob, I think Sammy might also be running the 5v reference from the MAP sensor to the TPS (C to C) the same way the Flash guys do. Sammy, confirm your MAP sensor wiring as per the P4 schematic. Nothing goes to the TPS from the MAP. Terminal C on the MAP sensor (5v reference) goes straight to the ECM. Terminal A on the MAP sensor (Groundd) should go to both the ECM and the CTS (B)...

Re: Installing EBL P4 for SBC TURBO PROJECT
Thanks gentlemen,
Looking back at everything I think that I went wrong at MAP-A pin….
I think that I should have rewired to MAF-A (black /white )
I’ll be going under the dash tomorrow after supper
I did splice into the TPS 5v under the hood

Re: Installing EBL P4 for SBC TURBO PROJECT
Sammy, wait for Bob to confirm the 5v reference lead off of the MAP sensor, as the P4 does not share that terminal with the TPS the way that the Flash system does. The P4 schematic will show that wire going straight to A4 on the back of the ECM from MAP Terminal C. No TPS whatsoever unless Bob gives the okay to splice into it...

Re: Installing EBL P4 for SBC TURBO PROJECT
Either way works. At the '7730/P4 ECM pins A4 & A5 are internally tied together. I listed it as using a MAF wire as it is easier then splicing into the TPS 5 V reference.

Re: Installing EBL P4 for SBC TURBO PROJECT
Getting there, need to set the 3-bar MAP flag and clear the 2-bar flag in the calibration and flash it in. The WUD should then also show that a 3-bar MAP is installed.
