:happydance:

I just tried the rev037 MAF tab. it's much "tighter" scatterplot than the previous test releases. With no ROM change, my scatter plot went from +/- 10% to +/- 7%.

I think tomorrow, Ty, I'm pulling the 3" MAF, and putting in a 65mm inlet (temp) to scale the injectors/latency tables. Then once they're squared away, put the 3" back in, and start on the MAF again.. THis "chasing my tail" trying to scale both, simultaneously, is for the birds

THEN, I'll start on OL again..

WTF? I DIDN'T post that in this thread! That went into the NA tuning thread!


EDIT: Crazy, the thread I actually did post that in no longer exists in the NA forum. It's been deleted or something.

Also, to post something actually relevant to the thread, I finally gave up trying to chase my MAF scaling in circles with the temperature changes and zeroed the temp compensation table. I'll see if it's any more steady this way, and if it's not, at least I can use one day's scaling as a starting point for building a new compensation table.

Actually, zeroing everything but the MRP compensation table seems to have helped things tremendously.

which maps did you zero? My engine load map came zeroed(don't know if I may have picked it up in a "stock download") I noticed that the MAF comp table will only let you select values of .8 multiples, which appears to be too big for what we want to do anyway.

Zeroed Temp comp of load and Throttle Opening angle comp of load. Mainly because both of those are either 0 or non-existant on other years of RSes. Considering zeroing the MRP comp of load as well, but other models do use that.

Educational read. This should be a sticky in the open ecu section as how to tune. How long did you log to get all of that data? Combined time...

It was just a trip to the store and back. Of course, the store is about 40min 1 way...

~1hr log is the shortest you can reasonably work from.

Just curious about what's the most amount that you can log?

You know, I haven't hit it yet, and I've logged for more than an hour a couple of times. The limit is either going to be the maximum Windows file size, or when the variable tracking Time in RomRaider overflows.

I would be interested in the answer to this as well. I would think the max windows file size would most likely be the limit. It definitely won't be the time variable (unless you plan on logging for the next 300million years ). If you were using the maf tool however I suspect it wouldn't last anywhere near as long due to memory requirements needed hold and display all the data.

I know I have logged for 2:30 hours straight once for my maf scaling. Yeah there was a lot of data!!

Oh and skimming through it to check for any knocking, not fun.

Don't want to use sort function because I want to see everything not just the highest knock count, I've tried and and looked at the data and said that was pointless. I want to be able to see before during and after. Have to be able to tell if it is slowly counting back to zero or if it pulls timing again. I have not found an easier way of doing it.

Actually, the bragging wasn't about the accuracy. That was actually pre-tuning. I cleaned my MAF and had to totally re-do the MAF scaling. It's about +-1.78 most days now. Well, +-1.78 of where I want it to be as I want it to be pulling a little fuel in a couple of the ranges so if/when my O2 sensors fail, it runs a little rich rather than a little lean.

The bragging was about my being able to force Excel to graph 35k points. The index variable overflows at 32k.

How is it that your IAT's stayed so low... Below temp of freezing for water? I know Ohio can get cold, but man... Unless you meant C instead of F.

How did you beat the 32k limit... I must know.

No, that was real. Looks like the outside temp when I took that was about 29F. Which, btw, is not really cold at all. 0F with wind starts to feel cold. However, I've been sleeping outside in Ohio when it was -30F, so that actually qualifies as cold.

Had to run it in two different series and plot them on the same graph.

That's pretty beast.

It's about 75F right now in Chicago, and I'm running 90F consistently on the highway with the hybrid intake cut a little short so it would draw from the fender. I hope something isn't wrong with my car. Oh well.


Now if I could get that stupid DBW map to work well with my TCU, I'd be happy.

(Not to be off topic but I did start another thread about it, much would be appreciated if you could help)

My K&N semi short ram runs about 15 degrees hotter than ambient, unless I am sitting in traffic.

Ok, cool, that's good to know.

I would like to think I'm running a little cooler. The summertime will tell I suppose.
