However the forums will remain available for view, they still contain a wealth of information on how MegaSquirt works, how it is installed and used. Although if the car is tuned for ITBS Alpha N style it will look a little bit different to regular style tuning. Hey, as some of you maaay know. 0 is the latest (last?) true DIY board from Al Grippo and Bruce Bowling. medium. Gruppe, I know many folks on this board understand quite well what Alpha-N is, but this is for those who don't understand it. The bottom line is if you understand terms like VE, MAP, MAF, and Alpha-N in Megasquirt, then stick to what you know and welcome to NASIOC! Alpha-N An alternative method of metering fuel is to use the throttle position sensor as the column index. Essentially due to the way things run, the MAP amount I have with KPA was a tiny window of maybe 30kpa to deal with, so the resolution was tiny. The software has a special ITB mode that uses the MAP sensor at low throttle / high vacuum and switches to the TPS at high throttle / low vacuum, for those using independent throttle bodies. MegaSquirt is the premier Do-It-Yourself EFI controller. For models with the v1. Unless otherwise requested, it will ship with the latest stable release of the MS2/Extra firmware. It's supposed to be the best of both worlds if you can get it tuned properly. Here is where I'm at today with my car. asm is required to load the code necessary for the upgrading of the software through the serial port. The engine was fun below 4500rpm (the removed T-VIS switch point), and then something changed in the tuning and was a whole lot more fun from there to the redline. We have extensive experience in many standalone engine management systems including AEM V1/V2, Haltech, ProEFI, MegaSquirt, LinkECU, Motec, Syvecs, Vipec, and more. by Mykk540i/6. The Traditional Megasquirt is not for everyone, but if you want to learn this stuff, the MegaManual will have most everything you will need to learn to tune your car yourself. Can work with a narrow-band (included) or wide ECU Tuning options Discussion in '80 alpha-n or MAF for fuelling calculations for tuning, the same software as Megasquirt. Megamanual Tuning Will I be able to tune the shift points, etc. Speed density, Alpha-N, Alpha-N Combination, and VE fueling strategies – Tuner has the option to select from a variety of load sensing strategies to meet their engine requirements or tuning preference Tuning der Alpha-N Tabelle []. This is the ultimate in control, using the MS3 setup, it has VVT control and SD card logging, providing a true Plug-n-Play ECU Firmware for MS-I chip. It is the exact same setup and tuning support we offer for our ECU customers, but accounts for the extra challenges that come with new relationships. Off idle ECU would revert to MAP algorythm all the way to full load. if the The issue of open headers of poor WBO2 placement can be addressed with an Alpha-N table (or a combo of Speed Density and Alpha-N). Alpha-N An alternative method of metering fuel is to use the throttle position sensor as the column index. Well over a decade ago, Fox-body fans rejoiced with the advent of the first replacement performance chips and piggy-back computers. It has also been a success because it further improved upon the stability of the system, while at the same time increasing the feature set and, importantly, offering a prototyping area for future modifications. First you should set your inovative to the 0-5v signal; That's covered in the inovative manual or on their Web site . Links to other MegaSquirt Forums: MSefi If you have questions about MS1/Extra or MS2/Extra or other non-B&G code configuration or tuning, Alpha N blending. Running Alpha N till I get a Map sensor installed close to the intake. 0-3. This section covers programming the MS1 ECU to run the 13B rotary. From supercharger kits, headers, and exhausts, to suspension and ECU tuning for your E46, we have it all. you may want to skip these. I usually recommend having the lowest amount of timing right at the RPM range where you want it to idle, then setting about 3 degrees more timing about 200 RPM below your desired idle speed. The engine I have built for my old Honda has rather large ( for the street ) cams with plenty of lift/duration/overlap and itbs to boot. " Herzlich Willkommen auf der Seite der Alpha-N GmbH. The set-up is described above. im looking at the megasquirt 2 or the emerald k6. Full details of each step are provided within I am looking at picking up a megasquirt-II programmable EFI kit. Bit confused, when the Fuel table is now converted to a load based on tps, why is the ignition table still Kpa load based?? I now only seem to be using the top third of the ignition load table? MX5 / Miata 1. There's a lot of guys on the Megasquirt forums who just use a MAP line plumbed to draw a signal from all the throttle bodies at once. Basic Setup: Fuel VE Table 1 The VE (volumetric efficiency) table represents the main fuel map for the engine and is where you will be doing most of your tuning. The current defaults are 50% at all points. Start up the tuning software, go to the Constants dialog and change speed density to Alpha-N. Did lots of research, trial and error, tuning and re-tuning on Speed Density before finally going to Alpha-N. It may solve some drivability issue tough. I know all the Infinity literature talks about the VE based tuning but can it also do TPS/Alpha N based mapping for ITBs? I assume it does, just checking 2 years ago he decided to ITB and Megasquirt his super high mileage 16V. ) Alpha-N takes the vacuum out of the equation entirely because it makes decisions based on TPS, ignition pulse, and oxygen sensor input. 30 for MegaSquirt Tuning Your MegaSquirt 112 density or alpha-N fuel control. where N is the number of cylinders. 5 bar MAP sensor 2 Ignition Inputs (for dual wheel ignitions) The MicroSquirt ® code can be used on MegaSquirt-II™, and thus MS-II™ can use a MAF. The TPS will be mounted to the side of the intake manifold. While tuning the fuel for best vacuum is generally a good idea, that doesn't necessarily apply to timing. Finishing my above project it is time to report as promised to Nick an James who supported me with some basic maps for my MS2 project. Very nice guy and helped keep it as plug and play as possible. not many other ecu's can do that. This is my (hey googlers) Megasquirt 20 valve 4AGE Alpha-N Spark and VE Fuel Map (s) for ITB from last week. 1 to Megasquirt from the incredibly unreliable (to me) Digifant, that I'm making a dedicated thread for it. It is updated frequently, and contains the latest information on assembling, testing, troubleshooting, installing, and tuning your MegaSquirt II includes all of the features and benefits of the original: Onboard MAP and baro sensor for NA or boosted engines up to 44psi (upgrade over standard 21 psi single sensor) Speed density or Alpha-N. htm 10/23 . Larry, to be honest I don't know if the ECU will definitely work to get the bike running, I bought it all in bits & I mean BITS!! Besides that I have to trust 30 year old connections & then chop up a brand new Power commander 5 to adjust the fueling. ) This is my (hey googlers) Megasquirt 20 valve 4AGE Alpha-N Spark and VE Fuel Map (s) for ITB from last week. I downloaded the free Tunerstudio software to get an idea (helped a little). The J-Body Organization, j-body. Note that this is the main documentation that is applicable to all MSPNP2 Platform ECUs. Using the speed-density algorithm, MAP is the main variable and VE is a 'tweak'. looking to get a engine managment system for my progressing red top which will be on throttle bodies. The tuning was through TweecerRT with a separate wide band. Tuning with Alpha-N. MegaSquirt uses Windows9x/ME/XP-based PC Granted, the Megasquirt requires a bit of study, and a lot of reading to get going as desired, but the flexibility is utterly mind boggling! The system code I'm running is MSnS-E , which stands for Megasquirt and Spark-Extra. The Siemens MS41. Alpha-N basically fuels an engine based on throttle angle and RPM (with similar fuel trim for temp, O2 sensor, etc. This is the index to the latest web-based version of the manual for MegaSquirt.

The alpha-N mode is intended for engines with very large camshafts that make using a manifold absolute pressure (MAP The MegaSquirt EFI System is truly the dream Electronic Fuel Injection computer for the DIYer. Speed Density, Alpha-N, MAF based tuning & blended algorithms ITB Mode – blends SD and Alpha-N for excellent drivability with naturally aspirated, multiple throttle applications! Custom blended strategies supported, mix/blend strategies to suit any engine Alpha-n tuning will be abbreviated 'AN' and speed-density tuning will be 'SD'. Depending on the size of the ITB's and the location of the MAP plumbing you may be better off with a full Alpha-N setup. it's for a NA 4 cylinder with ITBs and a big cam how does megasquirt compare to kalmaker? I have a mate with kalmaker and I'd need a real time ecm or a security PAL or I could go with MS. reason to use table 1 for map is because to use the electronic boost contro, l it has to be map and work off the "Primary fuel load" the way boost control is set up. MegaSquirt 3 Gold Box for Z31. The rest of the hardware is likely to be OK, but the analog Pro-Jection ECU is not appropriate for a turbo car at all. I decided to go MegaSquirt. MegaSquirt is a general-purpose aftermarket electronic fuel injection (EFI) controller designed to be used with a wide range of spark-ignition internal combustion engines (i. The system uses an O2 sensor so in idle there is closed loop operation. 00 Select options Start up the tuning software, go to the Constants dialog and change speed density to Alpha-N. Speed Density, Alpha-N, MAF based tuning & blended algorithms ITB Mode – blends SD and Alpha-N for excellent drivability with naturally aspirated, multiple throttle applications! Custom blended strategies supported, mix/blend strategies to suit any engine Alpha-N uses the throttle position ('alpha') and RPM ('N') to calculate the amount of fuel to inject as opposed to using the manifold absolute pressure (MAP) and RPM to calculate the amount of fuel to inject. Hybrid Alpha-N is more of a low load thing, like idle, good with wide cams that make low manifold vacum. Our Gold Box plug and play systems have become very popular, but many of our customers are requesting a universal system. TonyK. RPM) if you have a weak vacuum signal. alpha n tuning megasquirt
