how much are the adapters?

and what is the lag time for PTE 880cc injectors?

Thanks

Adaptors are $55 shipped. The lag time for PTE 880cc injectors are unknown. However, AEM will perform this service for free if you send them yours for testing. See this thread: http://forum.aempower.com/bbs/viewtopic.php?t=4619

hmm, I'll see if he has one left next week. What does it do?

So this data isn't true?::


Precission 880cc/min Battery Offset (compliments of Banzai)

6v 2550
7v 2420
8v 1860
9v 1440
10v 1200
11v 1010
12v 840
13v 710
14v 600
15v 500
16v 410

Another question I had was about the E-manage Ultimate Air/Fuel input Harness. Are you supposed to splice into your existing WB02 sensor setup or are you supposed to severe the WB02 sensor altogether and solder the wires directly to the GReddy A/F input Harness and plug it into the EMU?

The adapter is only necessary if you want to run stage 3 wiring with no CEL.

Reading from your PTE 880cc battery offset table, you'd have 0.84 ms of injector lag @ 12V.

Most wideband o2 controllers have an analog 0-5V output. It is this output you wire in the Air/Fuel input Harness. If you don't have an analog output, then you can't use that wideband.

I see stages 1 and 2 on page 1 but where are the stage 3 diagrams?

I plan on using the EMU with Speed Density, MAP, IAT, etc... I don't know if that 880 injector table is correct since I don't know if the 880s that were tested were ball and seat as well as low impedance by AEM. Maybe I'll just end up sending mine in when I get my injectors in the mail.

About the A/F input harness. I totall understand now My LM-1 has an analog output!

All 91-97 cars have the fuel injectors ECU pins located at the same place. So this means you can use the same stage 3 diagram I made for 91-93 cars for 94-97 too. The 98-99 cars I have no info on.

For most people, stage 1 and 2 is all they need. Stage 3 unlocks some of the advanced features.

After reading the English translation of the adapter instructions, I am thinking it is not optimum to drive around like this. My understand is that when you do Stage 3 wiring, the ECU detects inconsistencies with the injector circuits, goes into 'safe' mode (batch fire mode) since it can't confirm everything is 'okay', and throws a code and lights the lamp.

This is consistent with what I've observed on my car. With stage 3 wiring and no adapter, I got the CEL, my car ran extremely rich, and I had to adjust the i/j map with big negative numbers. (I believe this was counteracting batch fire mode.) Once I installed the adapter, I got no CEL, but had to throw out all my earlier maps as the rich condition was now gone.

I think Stage 3 makes sense with the adapter installed, but with no adapter, I'd just go back to Stage 2 and do all your tuning with the airflow adjustment map. All you give up is tuning with the i/j map, autotuning with the afr target map, and individual injector control. You have to decide if you need those or not.

THat would seem to be consistent with what I am experiencing... CEL usually comes on after 2 or 3 minutes of driving... it pulls pretty hard and the logs look pretty good... but it wil randomly hesitate as if it were too rich.

Also doing correction on only airflow map creates rich condition all the time. To the point where I can't lean it out enough using only the airflow map.

I think I will just go ahead and order up one of these adapters.... then I will put in some new plugs and do half of the correction on the i/j map and the other half on the airflow map (sorta how i'm doing it now but hopefully it'll be cleaner).

But for now it does run pretty clean and pull pretty hard (i'm even pushing 20 psi now... but i do have a lot of timing pulled i should probably readjust). It starts up, idles well, and cruises really well. Even after the CEL comes on I don't notice any problems with it being overly rich. I'm also not really leaning it out much on most of my map. Like maybe lean it out 2.5% on most areas... nothing crazy though... For idle and cruise I have it set for 655cc injectors and dont lean it out ANY extra (or richen it up) and it does great.

edit: I ordered up the last one they had in stock.

Did you guys have to wire in the adapter before or after the emanage taps the injector wires coming from the ecu? Or does it matter? I'm guessing between the ECU and where the EMU hits the injector wires.

And you put it on 12V ignition? yeah... that makes sense

Also, Mohd said he'd get in more adapters this week or maaybe next week if anyone here wants to buy 'em up.
