Okay so for those of us who have or are considering the RTLS1, I would like to consolidate and add instructions, tuning, modifying and other RTLS1 related information here.

So far I got my RTLS1 setup with bubbas boost OS 3.4. I managed to run it for about 5 minutes before breaking it. Not quite sure how, but Richard has been tremendously helpful. Currently, awaiting an eprom burner to see if it can be recovered.

In regards to what I was doing, I had made some live changes to the injector flow rate, then proceeded to change the ve table when the engine stalled and would not restart. I noticed then there was no data coming from the pcm anymore either. So, we believe and its very likely the RTLS1 board may have shorted to either the case or something on the pcm board as in my hast/excitement I failed to put the isolators as per the instructions Richard provided when I ordered my RTLS1. A potentially costly mistake on my behalf.

Update, with Richards help and a cheap amazon eprom burner I was able to recover my RTLS1 quite easily. Here is the burner i used:

Great news!

So I am close to starting my truck with the turbo fitted(hotside only). Before I had an old plx wideband 5v out wired into pin 55 for WB closed loop in boostOS, however, the wideband parameter in the RTLS1 did not appear to register the reading from the plx.

I have since purchased an AEM 30-0300 wideband and it has 5v positive and 5v negative. Assuming 5v positive connects to pin 55, Can/should I connect the 5v low to any of the 5v low reference locations on the pcm such as 5v reference MAP pin 48? Or is there an egr specific low reference pin I should use?

Do i need to change the address upon which the RTLS1 is looking for the wideband info? Here is where it is looking now which doesn't appear to align with any of the stock hex paramters I guess due to it reading from 2 chips. I believe Richard said its setup to read the wideband from one of the wires in the Ethernet cable, however, I suspect wiring it that way would omit WB closed loop?

[Element9]
uid=WIDEBAND
name=Wideband
address_hex=FFFF9B2C
unitname=WB_UNITS
isUnsigned=True
is8Bit=False
UpperBound=18.0
LowerBound=8.0
Inverted=True

I will also send Richard a message asking for the address to pin 55 EGR solenoid to see if I can add that element in the interim.

114B is the EGR address for the 5v signal. x/51 is the formula to convert the data to voltage.

WB formula is ((x/51)/0.5)+9.58

Thank you! I ended up finding that info in the universal patcher logging profiles. I was really hoping you would see this since you seem to be well versed in the RTLS1.

I created an additional element for the wideband and unit on the config file. When I did, it would no longer log. It appears you have added elements or at least modified them to work.

I haven't hooked up my new wideband to the PCM yet but I did find the 5v gnd needs to go to C1 pin41. For the egr address in elements I assume it should read FFFF114B?

I believe I found what was causing my RTLS1 to crash. I had not fully prepped my P59 for going DBW and needed to turn off all of the accelerator pedal codes.

Update on getting AEM 30-0300 to work with EGR input with rtls1 and boost OS 3.4. ECM blue pin 55 for signal or positive and ECM blue pin 41 for ground or reference.

For the RTLS1 settings, one either needs to change or add the following units and elements:
(I havent tested this in the car but on the bench it matches exactly with what the AEM WB analog 5v output should be putting out.)

[Unit9]
uid=WB_UNITS
name=Wideband
units=:1
low=0
high=255
operation=DIV
factor=86
offset=7.3

[Element9]
uid=WIDEBAND
name=Wideband
address_hex=FFFFF2C0
unitname=WB_UNITS
isUnsigned=True
is8Bit=False
UpperBound=22.0
LowerBound=8.0
Inverted=True

Yes FFFF114B is correct.

I don't think you need to disable APP codes to get DBW to work. I am running just fine without having to modify anything DBW related. The only issue I get is after a reflash of the RTLS1, I have to clear the codes as I get a "U0107 Lost Comm with TAC Module" which must get set while flashing since the "PCM" goes offline. Once cleared, everything is fine.

Are you getting throttle/accel pedal/TAC codes?

I am not getting any app codes, but I have them disabled.

FFFF114B I have found is the pid address. The hex address(I believe is what it's called) for pin 55 is indeed FFFFF2C0.

Are you logging your wideband in RTLS1? If so is FFFF114B the address you used?

My truck seems to be running without crashing the RTLS1 now(since turning off the app codes), albeit rather poorly as I'm still trying to figure out how to tune it.
