Not sure if this is useful to anyone but here were the Parameters that were in my GEMU

NFRad, you'd be surprised how well replacing a call to some security routine with xor eax,eax nop nop nop does at defeating security in programs

Can I use the existing sensor from my UEGO kit and just buy the innovate LC-1 lambda controller?

 

Received and installed new Boomslang harness for NA application with MAP signal tapped rather then intercepted. The part number on the bag was the same as the first one I bought, however when I placed the order they asked if the application was for NA or FI. In the photo below you can see the white wire tapped in.





The MAP tap did not correct my partial throttle miss/break up that can happen between 6 and 9k RPM. Only when the EMU harness is disconnected does the rough running go away. Again there are no codes thrown when this happens. Below is a data collection plot that shows some of the parameters bouncing around. The two full fuel drop outs were caused by the rev limiter. Since it occurs even with the tuning maps turned off I can only claim that the EMU is messing with something unknown??? Fortunately it runs fine when in open loop and to my knowledge has not caused an issue at an event. Although one time I thought I had minor fuel starvation coming out of a turn that could have been this issue when rolling on the throttle.

 

Well, if you have the very limited edition S2000 I6; sure, put JP5/JP6 to OPEN... So yeah, these don't matter if open or closed...

For JP8, I honestly don't believe it matters as Greddy suggests to set up as 12V output... other people were saying it could burn up coils... I have a spare set of coils I may test this with. I had thought the input signal is 5V, so if setting the output to 12V, it would most likely not matter, as it still only has 5V feeding it... but now looking through the OEM wiring schematics, I cannot find where it shows the ignition signal being 5V...

But looking up the coil specs, I did find this:

Ignition coil
Item
Measurement
Qualification
Standard or New
Service Limit

Ignition coil
Rated voltage
12 V

Firing order
1-3-4-2

So now I'm questioning if it should be set to 12V, but never had any issues with the 5V setting... I'm going to be playing again on the dyno this weekend and will mess with both settings to see if there is any difference...

I don't know if this helps you at all, but I was fighting with misfires for quite a while. All my signals seemed to have a lot of noise, and when the misfires hit, the datalogs showed huge spikes or drop outs with the ignition and injector signals. However, when tuning Rad's car, his signals were super clean and his car has never had a single misfire with the EMU. I recently removed some extra grounds I installed and also disconnected my WB from the switched 12V source that the EMU harness uses. Once those items were pulled, my signal is clean and I'm misfire free. Mine were hitting anywhere from 4-8k rpm... part throttle or WOT... however, if removing all corrections (setting cells to 0), they would seem to go away with the improper wiring... So yeah, it seems best if you simply have the PNP harness connected to the ECU and EMU and that's it. Tapping into the 12V switched source and ground caused issues in my scenario.

 

Is this a bug in the 2.30 software?

When I open Karcepts's AP2v1 EM2 file in 2.3 the Vehicle Speed Pulse/Adj. under the Vehicle tab has what appear to be abnormal values



I can't find the 2.2x setup on the internet just the 2.23 update from greddy. Anyone got a link to the 2.2x installer?

 

No, that's not a bug, just a difference between my map and the Giles map you have. The values on my map are simply the Greddy provided default values for the F20C motor. I guess Giles found those numbers more useful, so you might want to try those out. Values inputted here are irrelevant to myself and any Boomslang harness owner, as the Boomslang harness does not have the VSS input and output wired up (hence why I never touched it from Greddy's default). Now that makes me curious to know why Boomslang chose to omit the VSS...

 

Thanks for replying, sorry for all the dumb questions.

 

No problem, we're all learning...

 

Just wanted to let others know the AEM UEGO does work with GEMU.

I bought the GEMU A/F harness (P/N 15900912) and hooked it up to the White Line (0-5V output) from my AEM UEGO and it reads correct measurements. I have it grounded to the same bolt that the gauge is grounded to. I have a ground running to my battery as well as a fused power supply to the gauge.
