Yeah OEM is still connected. Thanks for the tip.

Fixed. Had a pin contact problem in the aux harness. All better now. I need a beer.

Did you have to modify the plug that plugs into the aux port? I had to dremel off part of the plug to get it to properly insert into the port.

No the plug fit fine. I had to change the diagnostic voltage for the o2 sensor to 5 volts max as default was set at 2.5 and it was throwing codes because the output voltage of the PLX is 0-5 volts. Just needed to push the pin farther into the plug to get contact and now the haltech is reading the wideband too.

Still running lean though. Anything under load and I get 16.0 afr or higher. My latency times are sort of a modified guess so not sure if the latency times can affect it that much.

If anybody has any ideas I am game. Wideband working, no codes, injector flow rate set, latency times a best guess. I have another set of times I found online that might be correct for my injectors but that is my last thing to try. I can also see if these need to be set to a high impedence because all the Deatschwerks I see are about 12.9 ohms and I am not sure what the map is set to right now.

My last resort is to try to get ahold of Deatschwerks first thing Monday morning at 9 am, but my tuning apt is at 10 am and it takes a half hour to get there. Hoping to get this in order so I can make my appointment and finally get a full tune on a standalone.

Did you try to lower the injector flow rate setting number at all and see what the outcome was?

Yes, that did not seem to work that well. I lowered it down to 500 (from 550) and it would still run lean under load. It seems to have a real dead spot between 2000 and 4000 rpm where it will run lean. I can try to see if calling Deatschwerks gets me better lag times (but I have played with those a lot, up and down and I don't see any real difference under load.

I am reading everything I can about VE and dead times and it seems they can make a huge difference in AFR. But the whole VE equation is new to me.

When I was first buying this kit, it came with a piggyback and I have no deadtime info. So I know they were Deatschwerks and 550's, but Deatsch makes no 550's specifically for the S2000, or at least not anymore. They have many different 550cc injectors which can range from dead times at 14 volts of 1.1 all the way down to .09 milliseconds. Does not make it easy.


I don't know how to tell for sure, but can I switch to another tuning method other than VE where deadtime is not a crucial variable and it will still have a base map? There are two other method to choose, but I don't know if they have a map because the default on the Plug and play was VE.

That I do not know. My knowledge of the software and tuning methods is pretty much limited to what we've covered so far in this thread, lol! Hope you get it sorted out. I'd suggest calling your tuner and seeing if he can help or maybe send you a modified base map to try.

I appreciate the attempts to help. I unplugged my boost gauge from a t connector that was also hooked up to my MAP sensor so that the MAP was the lone connection to the intake and that helped some. I also scaled down the flow rate as you suggested and that helps too. It is running a little rich at times and lean at others but I think I can at least limp it to the tuner this way and he can get it going. It has a strange dead spot between 2000-3500 rpm where held at a cruise it will sometimes be lean, but anything above that is in the 12's. Beats the heck out of me but I think the tuner can sort out the map.

Anyway, thanks again. It looks like I will make it there. I just did want anything lean under load (and now I am a tad rich) because it is about a ten mile climb out of the river valley to the tuner and it will be under some load most of the time. I think I am on the safe side now.

I've kind of been wondering this as well. Where has your tuner been throughout this entire process?

vader1

First time at this shop. Its my fault. I got the Haltech shipped to me later than I expected giving me only the weekend to hookup and sort out. Shop was not open on Sunday to help with any questions. But I keep tweaking the dead time and injector sizing and it seems pretty solid to drive now.

EDIT Got back from the tuner and things went OK but the whole problem was that my "550" are junk and flow about 475cc. Car runs well now.
