What standalone ecu do u recomend?!?!

[smoked240]

You can't compare ecu's when the tuner is shit.

A ecu will only performe as good as the person who tuned it.

You also realize you can change the smoothness of the graph on the Dyno too right?

[TheRealSy90]

Pick one of the better, decent ecu's and save up for it. When you've saved up for it and have enough just keep saving for like two more months and just get an Infinity setup.

Adaptronic Modular ECUs look real nice. I will be swapping out for one soon.

I was just about to ask about this...has anyone had any experience with Adaptronic? Ryan Litteral from Formula D is running this Ecu with his RB25DET and his car looks really good out on the track.

Looks like their are a few on youtube that I have found, its relatively new.

Speaking of datalogs etc this looks pretty trick!

That's a lot of driving on an un-tuned setup to create the tune IMO.

thanks for the post,

You can drive for as long as you want. You can drive for 5 seconds if you wish, and check the log and re-tune then go again. The "Driving for hours" was only after you had mostly tuned the map and wished to hit "all the corners", sometimes the engine only touches a region briefly once in a great while (see all the 1's?) Normally you would trim those ones, but if this were say, the 10th or 20th time you decided to log the data and finally had hit one of those points, you would want to look back at the moving map when you had hit that "1" to see if the data was good or not. Also consider when basemap tuning you can check nearby values to determine more or less if the box in question is a valid number, often the basemap of engines are fairly smooth, rarely will a box jump in value drastically.

Another thing to consider is that the reported values are "averages" which means it is also logging transient data. There is a setting which alters the delay before taking a value and recording it, so this is important for slowing down the logger (making it wait a second or two before logging a data point, vs letting it take a value immediately, can be setup manually) once you've established base map for driving. Remember that the values are loaded into excel where you will examine them, and change them. You can manually enter data into an excel box to adjust the increments, i.e. make them smaller or smoother. For example if you know a spot was very rich, but the determined multiplier were something drastic like .655 (65% of the original basemap value) you would simply click the box in excel and change it to something more rational- such as 0.850. Then re-run the engine, hit the spot again and see if it still needed some fuel removed. There is nothing forcing you to make large changes, you can always adjust up or down as you see fit (and I always do) based on the average, hi, low, and wait-period, and other data such as knock data which is also recorded simultaneously on another map, along with a myriad of other variables (a drop down box gives the other logged points for all the other sensor data) and you can also adjust it to show only values which were recorded above or below certain conditions.

Maybe I need to take a video of the process, but my camera is a piece of garbage after the lens melted from some brake cleaner (and its over 10 years old) so I dont know about just yet but I will think of something eventually. It only took me 10 years to make the picture above... sigh! It is easier and faster than any other stand-alone I have ever tuned, fwiw. Anytime you can log wideband data and go back to alter your fuel map is priceless $$ and many stand-alone can do it. You do not need an excel file for making adjustments, that is just to help speed the process (so I can stop the car at a traffic light, copy/paste any delicious adjustments and in 15 seconds have a new map loaded ready to go for more tuning)

Would it not be faster to make all these calculations and changes within the EMS software itself, and never have to leave the one program or mess with Excel etc? Like the Infinity software for example as well as the other "more expensive" EMS. You can do everything in the tuning program, even live while the car is being driven.
Hell the Infinity program TELLS you what you should change and where once you start driving it with the o2 feedback enabled. It damn near tunes itself from that point.


TLDR I'm an Infinity fanboy and you love PowerFC lol. We can go back and forth forever, but I know we can agree that for more money you DO get a "better" ecu, however the older options CAN be tuned to a similar accuracy if you put in the time and effort.

Depends how well you know computers. Being a computer tech/programmer I don't have any trouble dealing with excel while driving, the program is fairly simple to use. If you are unfamiliar with it, I can see why it might be scary to think of having to deal with. At the end of the day, there is little difference between the two situations i.e. both of the methods give you the result you want: a tuned map. The major difference is in the price tag, could cost us over a thousand dollars extra just to have it all included in 1 software bundle. If I can save thousand or 1500 by using excel to perform my calculation it seems worth it to me.

I tune everything. I prefer Accel for its user options. I am only showing how we can save money by using a pfc to do the same exact sort of things.

Also, I feel that you have "time spent" in reverse, the more time and effort is spent tuning the more complex ECU. PFC tuning is fast and simple because it has fewer options. Accel has so many options it can take a long time to fine tune each one, especially injector phasing, idle config, spark optimization, cold start, and so forth, of which the PFC has barely any of that. PFC I slap it on and done in a couple hours. Accel style ECU is days of work, perhaps 8 to 12 hours spread out over 3 days on new configurations.

I found a really old video of the power FC In my old 95' redtop car that I forgot about. It shows alot of things I just mentioned so I figured I would share it. This PFC I found in the back of my friends shop, on the floor, half covered in rust and looked water damaged. He had all kinds of stuff back there he didn't even know about. Indeed the commander never worked on it, but it connected fine and tuned fine with the laptop.

my dads car I tuned with a power FC and made a video.

"data-logit" plugs into power FC and turns it into a typical stand-alone computer. You can re-sell the data-logit when you are done to re-coup the money if you want. Use a popular wideband, drive the car around and log the values like this.



Get rid of un-sure data points, by examining the number of data-points collected, averages, minimum and maximum valves recorded, and by reviewing the chart to see how the map was moving when those points were being recorded. Here is an example.



The closer you are to a final tune, the more careful you will want to be when using recorded values. For an initial tune, most of the values are useful. Later, you will want to smooth them (make the changes less intense) and remove any low-quality data points.

Finally, you paste the result back into the PFC.



This is a very powerful feature because you no longer have to watch the fuel map while you drive to tune the vehicle. You can drive for hours if you want, then collect and use any valid data-points to re-tune the fuel map. This excel file is downloaded free from the data-logit web group where they also update the software.
