Control Characteristics
Map points 512 - every 500 RPM (0 - 15500 RPM) and 1/15th of maximum load (TPS or MAP) Same as e420b, but two ignition maps and two fuel maps.
Load determination TPS or MAP TPS or MAP
TPS using 2nd map as MAP backup
MAP using 2nd map as TPS backup
Both maps MAP or TPS, digital input to select
MAP and TPS map, digital input to select
MAP and TPS map, use MAP on closed throttle, otherwise TPS
Use max/min/average/sum (MAP, TPS)
Read TPS from map and multiply by value in MAP table
Injector pulse width resolution 0.7µs (0 - 44ms)
Ignition resolution 0.2° (0 - 51°)
Dwell time resolution 0.1ms (0.1ms - 5ms)
Dwell time reduction for high RPM with high dwell time
Accelerator pump TPS and/or MAP based (configurable proportionality) as well as asynchronous accelerator pump (function of RPM)
Works with TPS pot or switch - pot gives better performance
Fuel control strategies Open loop, closed loop, and two adaptive modes (requires EGO sensor) - can run open loop above a specific MAP if required, target AFR can be set across rev and load ranges.
Fuel correction Open loop, engine temperature, air temperature, accelerator pump, post-crank enrich, cranking enrichment, WOT As e420b, except that air temperature now has a temperature table rather than a fixed coefficient
Ignition control strategies Open loop, closed loop and adaptive (requires knock sensor, alpha version only) As e420b, but with temperature correction table for air temp and coolant temp
Idle control strategies Open loop values for hot and cold (2 points)
Target speeds for hot and cold (2 points)
Throttle cracker (VSS increase and change to open loop)
Extra for electrical load and aircon
Post crank idle-up Open loop values with a 32-entry temperature table
Target idle speeds with 32-entry temperature table
Idle effort correction for air temperature
Other corrections as on e20b
Main loop speed 200Hz approx

Wow at that price and being a little creative on sensors and some of the less expensive ITBs it competes with PMOs doesnt it?

Certainly does! I just paid $500 for a MAP-ECU piggy-back computer to eliminate the Carrera's AFM using speed-density sensing. This is only $500 more and offers me full fuel and ignition mapping

Certainly worth considering!

Curious, how would one setup the trigger on a Carrera engine? Does the Motronic use the Speed and Reference sensor that's on the flywheel to trigger the ignition?

If I fit a 964/993 twin distributor (my heads are already twin plugged), they already have a built-in sync signal right???

A built and tested Megasquirt II version 3.0 runs around $400.00.Just a reference for cost.

[JohnJL]

Crikey, those aussies are clever.

[Elombard]

R Fuerst how much were the ITBs for your set up.

[mb911]

the megasquirt II are the best bang for the buck. Very well designed and work with a bunch of different applications. If I were to boost my own 3.2 I would do the mega squirt prior to anything else. I was so impressed with the tunning process when I boosted my 3.0 with the mega squirt I would only go that route if to do it again

[rfuerst911sc]

Elombard the ITB's were $1100.00 and that includes the fuel rails and a fuel pressure regulator. Then add $86.00 for a TPS sensor and $250.00 for 6 velocity stacks = $1436.00. I used some old Weber manifolds I found cheap and was able to use the OEM throttle linkage from a carb'd car.

[Elombard]

Holy cow so you have modern programmable FI with ITBs. You could build a wild motor withthat set up and it was only $2K!! Thats fantastic. I am surprised any body buys PMOs any more. Heck thats barely more than a nice complete set of used webbers.

[rfuerst911sc]

Well there is more cost as you have to buy air cleaner housings and filters,fuel injectors,wiring harness etc. plus I went with a relay board. When I add up everything I'm around $3100.00 or so and that is buying some items used.You also have to configure fuel lines and I went the extra mile and used ss braided hose with ss fittings, this is overkill but I didn't want any leaks.There's also engine temp sensor,air temp sensor and lots of little items. Still money well spent for tuning capability,throttle response and the look of the engine compartment is amazing compared to CIS. You can save more money if you build the ECU yourself.

[WydRyd]

Just an update on this, the dealer has quoted me AUD$2k to install and tune this system on my car, which equates to approx USD$1.4k

That's a pretty good deal for a complete standalone engine management system, with features that's on par with Motec and Autronic EMS's.

Certainly worth considering...

[JohnJL]

I run this on my car now and am mostly happy. Everything works as advertised and Andy is a great guy, however it does NOT support EDIS. That required acquiring Haltech ignition units to drive the EDIS coils, but works good now.

Nothing like having the designer/manufacturer 2 kms from your house...

Here is an even cheaper way to add ITB's. Suzuki Throttle bodys, in this case from a GSXR 600 which will be good for the NA 2.7 I am building. By taking my time I picked up a pair on Ebay for <$100.00, add a fuel rail for $50.00 plus a pair of weber manifolds for $125.00, and $100.00 worth of misc parts and some work. I may or may not use the Air Horns shown, but they only cost $96.00 for the set and are available in a range of heights.



Of course you still have all the other usual stuff you have to buy like fuel pump, injectors (I used Honda injectors as they fit the suzuki injector bungs) etc. But the throttle bodys themselve are cheap, even if you have to go to a Hayabusa set for a large bore motor you can get a pair for $400.00.
