Megasquirt Support Forum (MSEXTRA)

94' Saturn Coupe, t3/t4, stock motor, 720ccs, Running 2.1.0p, had it running pretty good for about 2 months and made 202whp on only 7psi. Upgraded firmware and now I'm trying to get it running again since it doesn't want to start.

1991 325i
2.7i stroker motor with super ETA pistons, Dbilas ITB's, 292* dbilas cam, cone filter with custom airbox, ebay headers, no cat, magnaflo muuffler for resonator, B&B cat back.

no dyno results as yet.

running MS2 extra 3.1.1. with wasted spark, launch control, batch fire injection, on a modified stock wiring harness.

Just made the jump from MS1 to MSII.

Rewired the whole engine bay and power distribution. 1999 Mitsubishi Eclipse, 2.4 swap, Garrett GT3076R, Crower Stg 3 Cams, RC 750s.

MSII v3.0, sequential injection, 4 bar w/baro, p&h board, full standalone on 3.0.3y.

Mine is running also:

1973er Beetle 1303 with MS2extra V3.11
here are some pictures and a movie

Hi,

this one has a 12-1 Hall-Trigger and a MS-controlled spark now:

It is based on a Simson/Awo 425S and modified for classic races:
- around 100kg when ready for takeoff
- 247cm³, bore/stroke 68/68, hemispheric combustion chamber, compression ratio ~10,5
- very lightweight ohv valvetrain with aluminium push rods and hair-pin springs
- around ~22-24hp@~8500rpms
- at the moment one 30mm carb

If i find a solution for enough electrical power (the space where the alternator was sitting was cut away to save some weight) the next step will be to remove the carb and fit a 35mm throttle-body and an injector.

Best Regards, Mario

Recently joined the ranks of Extra code, on 3.1
My project is listed over on the success stories, but it changed physically so drastically this winter, that by rights it is like a different machine, and project really.

Details:

-1983 BMW R100RT MotorBike (988cc air cooled, opposed cylinder boxer engine, Nakasil liners, dual plug heads, etc.)
-Delphi injectors, sensors, MS ecu's, LCI wide band, etc. & much advice from helpful guys @ DIYA
-Some donor parts from Honda CTX650 "turbo" donor bikes (exhaust "Y" collector castings, and dual throat throttle plate plenum chamber assembly)
-Mitsubishi #TD025M-08T-3.3 Turbo, with aftercooler fabrication from 1/2 core from Sabb 900
-Exhaust manifold pipes and outlets from 321 SS mandrel bends (to avoid the ever hazardous "intergranular corrosion" that results from high turbo manifold temperatures)
-Water injection with miniature Peerless 12vdc diaphram pump that develops 80psi @ 120ml/min through ultra fine SS fogging nozzles from MacMaster Carr stock. 4L reservoir is hidden within rear upright seat.
-Tested to 23psi boost levels which correlate to uppermost rpm zone of turbo map, but presently tuned to 7psi.
-Stock bikes with Bing Carbs require highest octane gas to avoid "pinking", however I'm able to now use lowest octane without issue (and at substantial savings) Other photos or details available
Almost forgot, underachieving stock Bosch crankshaft mounted alternator (280W on a windy day) upgraded prior to MS project, with a 900W compact Mitsubishi Alternator (by upgraded I refer to serious fabrication and machine work to shift to a frontal belt drive system - however was ideal lead in to a project that tends to request more electrical power every time you add something.

BMW M50tu (Vanos)
running entirely on stock sensors and loom
19lb ford motorsport injectors
ms2e 3.1, batch fire,wasted spark COP fired of oem drivers
currently running on another MS user's 2.8 map
starting refining tonight, car runs close to stock already very pleased.

I run a MS2. It took some time but I built everything. Help is very hard to find when it comes to programming. Take a look at the finished product. I have a 15" flat screen to display everything. http://www.youtube.com/watch?v=gRm88aeayAA

I have 3 engines running MSExtra.

20v 4age sc14 supercharged running on MS2 extra. Using stock dizzy and the Zeal engineering daughterboard. Wicked cool.

Triumph 2.5 PI previously clockwork then MS II B&G 2.89. Runs ok though the firmware change has deranged the fuel map somehow - need to map it again.....

Thought I would update this post with a dyno sheet (Check link for full size image - forum cuts the thumbnail resolution in half)

Nice numbers!

running ms2/extra in my jdm ej20g tdo4 powered porsche 914. 6/7 trigger. took a while but it runs great.

1976 porsche 914, jdm ej20 subaru motor, tdo4 turbo. here is a list of most of what i have done to the car. new carpets, head liner and mats, new window cranks, rebuilt door handles, customized driver side door storage, rebuilt glove box, custom rear panel, custom air intake in front to radiator, extra hood release, pioneer deh-6300ub stereo and 4 speakers, custom center console with 4 gauges and 2 speakers (innovate air/fuel, oil pressure, water temp, boost), customized shifter with custom boot, refurbished visors, ate vw fox big brake upgrade in front, rebuilt rear calipers (green stuff pads), new hard and flexible brake lines, new 19mm master cylinder, replace proportion valve with “t” fitting, new clutch cable, customized rebuilt peddle assembly with brass bushings, custom shift linkage bar, jdm ej20 subaru motor, 250 hp stock (450 cc/min injectors, relocated tdo4 turbo, wrx intercooler, custom tubing), summit electric fuel pump, kennedy adapter and fly wheel, stage 2 clutch and pressure plate, custom 3” exhaust, stainless ansa muffler, cx racing 3 core aluminum radiator with 2 12” electric fans, custom radiator cowl, refurbished fuel tank, electric windshield washer pump, 140lb rear springs, ats 15”x7” classic wheels with bfg sport tires, battery relocated to trunk, megasquirt ecu (ms2/extra, tuner studio running modified sti ignition map, innovate wide band o2 sensor, electronic boost controller), custom heater core in modified stock heater box, custom rain collector in engine compartment, stock engine temp. gauge used as oil temp gauge, custom rear wheel fender liner, among other things. photos taken before springs were installed. looking to get on the dyno in the spring, aiming for 275-300. any questions just ask.
finally made a video, check it out at:https://www.youtube.com/watch?v=7QBvLg2ulqM

Citröen engine XU10J4RS (or RFS).

Original: 4 cylinder, 4 stroke, 2.0L, 16 valves, 167hp.
Before MS: 136whp, gasoline.
After MS: 189whp, ethanol.

My car is a 1960 Lotus Seven home-built replica (not a kit) running a ’91 Mazda RX-7 normally aspirated rotary engine. The engine is rebuilt as stock with a custom intake manifold and headers. Crank angle sensor has been modified with 2 missing teeth. Oil injector pump has been eliminated. I am running premix. I recently added Bluetooth communications for 14 bucks. I’ve been on the road since March and have had over 2,000 miles logged. I’m still doing some fine tuning when I get the chance.

My setup is MS2 on a V3.0 PWB running 3.1.0 firmware. The MS2 is controlling fuel and ignition, dual speed fuel pump, Aux ports, and cooling fan. MS is wired directly to the highly modified RX-7 wiring harness with no expansion board, just the main MS2 controller.

I have an R100RT I would like to EFI and would like to get in touch with you about some questions I have about your bike. Is there a PM function here?

Sure "Les_Garten", I believe if you go to a person's post and click on their signature, that takes you to a page where you can email and such.

1972 Volvo 142e, B20. It was formerly injected via Bosch D-Jet.
B20 is a 2 liter pushrod 4 cylinder. predecessor to the B21/B23/B230 OHC motors.

Currently running MSII, extra 3.1.1.
1000cc Delphi injectors with resistors, GM 2 post coils in wasted spark driven by BIP373 coil drivers.

engine is 8.7:1, Holset HE251cw turbo, few other things going on.

cold start is perfect, still working on warm up drivability but it's not horrible.
once it's at operating temperature, drivability is better than it was at it's best with D-Jet.
cruise is good, WOT is an absolute blast. boost comes on like a freight train.
