Bipes ACU

[rhysmate]

If you really want great value for money the megasquirt is a serious ecu.. its not as difficult you may think, once you have your afr tables set up properly you can run it through ve analyse live and it will give you a good base to get a great map going. You may find you need to adjust the idle a bit though.

People lik Steve have alot of knowledge on other ecus.

Do many professional mappers do stuff with megasquirt in ireland?

There's a man called Joe power in Dublin and he knows megasquirts very well.. he mapped a pro drift mx5 to 236 HP a couple of years ago.. 1.6 engine fairly close spec to my own he quoted me 300 for a full map from scratch but I haven't called him since as I didn't have the car ready for him. fairly sure tdp do too

Megasquirt is a really good value for money. The bad part is that if you assemble it yourself, then the reliability is really up to your welding skills...
It doesn't have a good reputation from mappers because of this, as they already have a hard time with cars that are not ready for mapping when they show up: play in throttle position sensor or linkage, air leaks, misfires, etc. So they don't want to end up fixing issues inside ECUs as well, that's a waste of rolling road time.
That's a different story for ECUs that come pre-assembled and are plug and play like the MSPNP ones sold for MX5s, then there is no human error factor.
Also, DIYAutotune has just released a new MS3Pro ECU to target professional installers, with better Ampseal connectors and all the features from the MS3 + MS3X.. The price is over 1k€ then, but it has the same features as the top of the range stuff which cost even more.

The tuning software "Tuner Studio" is really smart stuff, the VE Analize Live feature, for example, changes values in the VE Fuel table according to the wideband feedback compared to the AFR target. And this with a user-friendly interface that make some other softwares look like MSDOS.

I know a few 205s in France running over 400hp on MS2. Now perhaps I'm proving charged RS point by saying this, but my own 205 is off the road as the Megasquirt CPU eventually died, but after years of driving the car daily and fidling with the ECU, adding features now and then. No regrets, I learned a lot with this, and I can buy another one it will still cost me less than what I'd have paid for an Emerald/DTA/KMS/Sybelle/etc..

with dyno time though you'd be ending up close to the cost of a second mx5!

What other ECU/ACU options are there?

A rolling road is not mandatory for mapping. You can map it on the road.
I'm not saying that road mapping is better, as it's probably very convenient to tune the car without having to drive around trying to reproduce all conditions while data logging, and having a proper way to compare power and torque between 2 runs to see if you're heading in the right direction is very handy I guess. You can also use a G-Tech or some smartphone app like Dynolicious or Perfect Power, but it's time consuming, probably too much for most professionals to bother with.

I'm a hobbyist, and therefore I prefer doing everything by myself, as it's a good way to learn electricity, bodywork, welding etc.. I might not doing it right or best, but at least it's keeping me away from the pub.

Here's some very good, free software for programming and tuning :http://dataloglab.com/

This stuff used to be paid for, but has gone free recently.

All of my tuning was done on the road - using 3rd gear power-runs from near idle to redline, and all manner of driving speed, load, etc in between. With a bit of care, autotuning like this can get you good, safe power. However you need to go 'manual' in order to smooth out the bumps between zones (in the fuel map and the timing map). The ECU will also record 'knock' events, so you have to manually tune those specific areas.

It's quite easy via a spreadsheet (one you have downloaded runs from the ECU) but software like DataLogLab can help make it easier still.

Thanks for that Software Frank, I bookmarked it I might use it at some stage..

For Megasquirt, the programmer of the realtime tuning software "Tuner Studio" also made an app to read datalogs offline: MegaLogViewer
It opens the maps + logs at the same time, and can even modify the fuelling with the same "VEanalyze Live" feature as in TunerStudio

There is also a version for non Megasquirt users:
http://www.efianalytics.com/MegaLogViewerHD/

Supported Data Logs:

TTS CSV Exports or native DM3 files
Power Vision log files
Power Commander log files
Motec csv Exports
Electromotive Tec II and Tec III
Pro EFI
Vi PEC
TunerPro RT Exports
Twin-Tec & Twin Scan log files, no need formating or data massaging.
Most GPS Output Files
Many Many more, load nearly any csv or delimited file formats. If you find a delimited log file it doesn't load just contact us at EFI Analytics, ods are we can have a version that will load it in no time.
