A few other people have ran my ROM with a wideband and also said it gets a little lean for them also. One of the guys also datalogged my ROM and said the same thing, but he was at a higher elevation (I guess that would make it a little more lean for him since I dyno tuned at sea level?).
atleast your ---- idles :-). thats an improvement.

I'm going to post on the uberdata site for some help

What have you did with your fuel modifiers? In my ROM they are all set to 100, but I have the cold and TPS enrich set to 53 right now. My car idles perfect with them set either way though. I think gimpy is running my ROM and he had to set the main and TPS enrich to 53 to get his car to idle well. I think he posted in the uberdata forum about it.

Your car may be running rich on Pats map do to the fact that he ran 10psi on the dyno, therefore only those cells are accurate. I took a peek at Pats final map, and would 'appear' to be ok at lower boost levels, but you said your plugs are black

Here is a link to an updated version of Pats map. The fuel modifiers are corrected, a sleep deprived oversight on my part. I adjusted the timing to were it should be, just load it up and set your base timing to 16. I also smoothed some of the fueling and fixed some timing discrepancies. Pat I wonder wich A/F printout you have. I have a few of yours, but not the final. What did I write on it?, or what is the time stamp on it?

As far as other peoples WB results, I would trust those #'s over what the dyno put out. This is a graph that I made of one of my runs. Its Dyno A/F vs my PLX datalog. Notice that the dyno sniffer lags about 500rpm behind. Makes tuning a bit more difficult. In my Hondalogger logs, I can see an almost instantanious (less than a second, or 100rpm) change in A/F logged vs injector pulse width changes.



Note: The Dyno sniffer was having some serious problems that day, it was slow to start reading and would then peg lean near the end of everyones runs.


Is there any way I can get ahold of someones WB datalog of your bin Pat?

As far as running to rich at lower boost levels, well bump it to 10psi, and youll be just fine :P
