Greddy EU install, need help.

Greddy EU install, need help.
Got the wideband in my 3.5 swap today.
Nick liked that little guage gadget, so I let him take it off to borrow for 2 weeks so he can look at his Honda's A/F. He plugged the bung with a cap scew. So, that's about it for the WB for now.
I've been reading up on the EU installs, Got a good feeling of what's going on. But I'm very unsure on the jumper settings inside. This EU I bought was used, and it was used by a Mitsu Turbo Eclipse before. So I'm sure my jumpers need to be re-done. Anyone can help? I need all jumper settings known.
Also, what software versions will definitely work this EU with our cars? I have the 2.0, but need to know if this would already be okay...

v2.0 is the best for our cars as it can read our crank sensors.
I think we should have the jumpers as they came from Greddy, but the guy you bought it from might have changed it as you said.

Yeah, that's exactly what I was worried about. I did go throught the manual a little bit, but they are a little vague on the jumper setting descriptions. So I hope someone here can point out all the exact jumper settings for our cars so I can do it right without messing anything up...

For the 3.0 ECU/sensors the jumpers will normally be:
JP1 to JP6 - default (OPEN)
JP7 & JP8 - default (1-2)
JP9 - default (OPEN)
JP10 - change to 2-3 if using auxiliary output (eg - as an rpm switch or relay driver)
JP11 & JP12 - default (OPEN), if using pressure sensor or WB
JP13 & JP14 - change to 1-2 if using for air and/or water temp, otherwise default (OPEN) for KS
JP15 - default (1-2)
JP16 - default (OPEN), generally not applicable to us
JP17 - default (1-2), generally not applicable to us
JP18 - default (OPEN)
JP19 & JP20 - default (1-2)
.......

Yeah, I've just cleared off a few messages, you should be able to send now. Sorry, too many pm's per day, don't have to time arrange and delete.

This should give me enough time to master EU installation, lol.

Yeah, I'll be glad to help. Your car's already a beast. With an EU, I won't be so audacious to challenge you anymore. I'll show up to this week's meet again on Thursday night at 10pm. Hope ya'll to come, too. My car is finally ready.

Dandymax, I have another question...
If I get the EU installed and run the base map and datalog for a while, I'll be able to see the fuel map layout, right? also, advance timing, right?
If so, can I then swap in a jwt ecu and hook up the same settings to datalog to see the fuel map layout and advance timing?
Basically, I want to know if EU can be used to tell the exact mathmatical difference between the jwt and stock ecu by datalogging the two.
Thanks.

However you won't be able to perfectly nail down the EXACT timing curves (and therefore the difference also) between the 2 ECU's because the EU logger is very sensitive and will show even small fluctuations (which can be a good thing sometimes and other times not). But you will be able to get an average/trendline, and a reasonable comparison from that.
Also, perhaps you are already aware of this, but I'll mention it in case you're not: the type of timing logging/comparison you are talking about has already been done with OBD2 scanners and WOT curves posted a few times in the last couple years. A quick search of this forum should find them...

Right, I have seen most of those curves already. But I also noticed how JWT gets to douchebag their maps a lot. I've seen different curves from 3 jwt ecu's. It may be mod variation related, but I'm skeptical that jwt does the same fuel map and advance timing for every ecu they send out. This is why I would like to see the difference between my own stock and jwt comparison.
But your explanation is great, I totally understand the proverbial "trend curves" you're talking about. And that's exactly what I was looking for. Thanks for the help.
