Just noticed this from diyautotune.com
A MS PRO mini... https://www.diyautotune.com/product/the-ms3...-mini-ecu-only/ That is a KICK ASS little ECU that has long term fuel trims, VVT support, E/85 support and a bunch of higher-level ECU functions for $600! This should work great on any 4 cylinder. On a 4 it is sequential fuel/COP spark. You can run waste spark on a 6-8 and sequential on up to 8 injectors. It's got abilities that a T4 will never need but at that price point I don't think it can be beat. Had it been available when I bought my M3X P+P (MSM Miata) from them I would have gone Pro mini. I'd have saved $500... |

Oh no, I think they are all generally pretty good quality. On the first micros there was crappy speed pickup noise rejection which would result in loosing speed sync. It was mostly a problem for inline engines, particularly out of bikes. So it didn’t really matter to most people, but it really sucked for me and caused me to curse the DIY auto tune name for a few years. (IMG:style_emoticons/default/laugh.gif) Most inline motorcycle engines have a redline DOUBLE what a T4 does... Some are a factor of 3! Running ANYTHING on a 12k+ engine is a serious challenge! It's a wonder it worked at all. When you "do the math" there is not enough time at 15k to complete a "fuel burn" across a 2" bore. Get close to a 4" cylinder and you NEED double the time! @jd74914 You were PUSHING HARD! |

(IMG:style_emoticons/default/aktion035.gif) Sequential ignition/injection is really needed at these high speeds to give the injectors and coils a break (obviously depending on component and ECU driver selection). After the Microsquirt failure we went down the PE ECU (worse), then Adaptronic e420c (great product!), then Life Racing F88/Syvecs S8 route. Basically went from backyard to LMS-grade. (IMG:style_emoticons/default/laugh.gif) The more expensive stuff had much better signal processing with dedicated FPGAs. If I was starting again I would have bought/designed a signal pre-processor so the Microsquirt only got a square pulse-live and learn. |
