MEGATUNE GENERATE AFR TABLE PROFESSIONAL
Information provided by the Speeduino Wiki and its authors is general in nature and is not intended to be a substitute for professional advice, including but not limited to, mechanical, electrical, theoretical, and safety advice. Widebands need a controller (usually come as a kit) & you need to understand the setup, many of them need some sort of calibration and you need to change settings in MS + TS to tell it it's got a wideband and make sure everything's reading right. AFR Table (for A ir: F uel R atio targets) Page under construction. It will get the idle zone wrong, but you can eyeball that. You can datalog & use MSTweak3000 (more old technology) to calculate the fuel table tweaks to hit target AFR's. You can use Megatune's auto-tune to get the map close (but NOT the idle or high-load/rpm areas), then dial the rest in by eye around it (see option 1) keeping an eye on the O2 reading, basically try to avoid going lean at high load/rpm. Also, I suck at tuning so mostly get it close enough then lose interest the regular EGO correction sorts things out when you're cruising along anyway so MPG doesn't suffer too badly if you've landed somewhere within its adjustment range.Īs someone said earlier, you can tune the old fashioned way by feel. I've never run a wideband on any of my megasquirts. One thing they did write to me was that the narrow band sensor voltage range should be between 0-1V, sent me a chart and all, very mathematical, but then why does the program spit out 1-5V? how can that be if the program has the right math formulas? Still trying to get more info out of them, maybe my simple language one question emails will finally get through to them.on a level they can answer. Port Checker will tell you which com port MicroSquirt controller is connected to.
MEGATUNE GENERATE AFR TABLE SOFTWARE
MegaLogViewer is the software application used to view datalogs. The latest version for Windows, Linux, and Macintosh can be found at. MegaTune Configurator is the program used to set up MegaTune (not MicroSquirt itself) to display things like wide band AFR, different temperature units., etc. Latest Tuning/Utility Software Revisions TunerStudioMS is the software application that is used to tune your MegaSquirt EFI controller. So, if you are as confused as me about the information above then good. MegaTune 2.25 is the tuning program itself. they say the voltage table is because of narrowband
MEGATUNE GENERATE AFR TABLE HOW TO
they recommend wide band but not sure how to stop the program giving you a AFR voltage tableĥ. Or you could just manually enter that value. If you use the use the required fuel calculator in MegaTune for 67 ci (1102cc) you should get a required fuel value of 8.8 IIRC. they don't really know why this happensĤ. As for tuning tables, I would be happy to give them to you but you have to have you required fuel value set up the same (I think). DONT ASK THEM MORE THAN ONE QUESTION PER EMAIL.they only answer the last oneĢ.
MEGATUNE GENERATE AFR TABLE UPGRADE
I can repair or upgrade Megasquirts in UK. Without 'multiply map' the ' MAP' is removed. With incorporate AFR it becomes: PW ReqFuel VE (rpm,map) MAP stoich / targetAFR (rpm,map) GammaE. Disable Accel Enrichment by setting TPSDot Threshold to something high like 40. The basic fuel equation (simplified) is: PW ReqFuel VE (rpm,map) MAP GammaE. Disable EGO correction by setting the authority to 0 and step size to 0. You haven't driven the car at this point. I was getting the same 5V AFR table that you pointed out in this post before and emailed TunerStudio to try and figure it out.ĭoing this I have learnt a few things.ġ. Then use the 'table transform' and 'shift' tool to pull a couple of degrees of timing from the entire table to start with- to help add a degree of safety. It is designed to work in Mozilla Firefox 6.0, though it may work with other browsers.Fatboy. This is a tool for establishing a baseline spark advance table for your tuning efforts with MegaSquirt® or MicroSquirt® controllers. Then your MegaSquirt-II controller will adjust the amount of fuel injected based on the AFR table until the wide band controller reports a voltage corresponding to the air/fuel ratio in the appropriate cell of the AFR table. If you have a wide band oxygen sensor & controller, choose 'Single Wide band' under Settings/EGO Control in TunerStudioMS, and be SURE to go to Tools/Calibrate AFR Table and select your controller type.
