FIC2150 tuning notes

got a bit more drive-time. for e20, 1539 cc/min seems good. i had to drop latency by 0.025 ms (smallest step size). i put the pulsewidth linearization values back to my e85 values, but will probably have to make a few tweaks to the table to get afrs fully optimized.

So the pulse damper works and is a good upgrade? My car also has a weird lean spot around 2250 that I can't seem to tune out...
Will installing a fuel rail and damper from radium have an affect on other parts of the tune? I feel like a higher volume fuel rail could make afr's globally rich...

yeah, the damper works, although i don't think this one is 100% effective (due to its overly simplistic design). word has it that radium is working on their own damper (vs their current offering which is simply a bosch damper). i will likely try it. a number of people say that a damper is not needed for stock rail and fpr. what you got?
big rail will not affect fuelling except in the case of the prior rail being undersized and causing a pressure drop along the rail.
damper will only fix resonance-based deficiencies. will not affect overall tune.

Ordered the Radium Evo9 fuel rail kit and damper today. The rail looks to be good quality unit.
And now you say they (Radium) are doing their own damper, kinda wish I had waited a bit now.

2250 rpm is the right place. if you still have stock injectors, see if installing them gets rid of the lean spot. i'll loan you mine if you want. i'm curious to see.

I might have them somewhere. Somewhat questionable as to whether or not they'll be gummed up with old fuel, they've been sitting unused for well over a year now. I'll try them if some more tuning tweaks don't help.
Unfortunately, company's only get good discounts on shipping that they use a lot. If they don't do international a lot, they get charged a lot. At the last place I worked, we only used UPS, but our rates on everything changed monthly depending how much of which service we had used the previous month...

I got it fixed. Finally got it to replicate while logging. Car was going into open loop (load was 95-110), so I just added fuel in the fuel table. Increased units by 8 in the Asynch vs tps delta table and it no longer goes lean on tip in or after shifts. It works, but makes my fuel table look funny with the block of rich fueling in the middle of the very top lol

My Radium fuel rail kit arrived today, looks to every bit as good quality as I had hoped for.
Unfortunately, it seems I have ordered the wrong kit as the kit I now have has no fuel pressure reg adapter or flexi hose. And I now have two fuel dampers, which do not mount to the top centre port on the rail and so I will still have to buy some adapter for that. This is getting messy.

I figured I would have to get an adapter locally to fit the damper.
Speedflow is made in Oz and they do a zillion fittings and adaptors, so that should not be much of a problem.
Hopefully it wont cost too much to get the other parts from Radium sent out.

For the most part. It's just about perfect most of the time, but it still occasionally goes quite lean right in that spot (17:1 or leaner), it did it this morning on the way to work pulling away from a stop light, and I wasn't logging (of course). So, I'm going to start bringing my laptop with me everywhere I guess...lol
