http://www.diyautotune.com . They charge $193.00 for MS1 V3 complete kit (including case), which is 97 quid. The complete MS2 V3 was $253.00, 127 quid.
D'ya reckon that is reasonable or rather over the odds. I did shop around quite a bit and thought it pretty competitive. They seem to have a very good reputation as well. These are unassembled, in component form - the fully built MS2 V3 clocks in at 206 quid, which seemed reasonable compared to eBay and various other sources (negating shipping and customs, of course, love relatives

). They included a harness so you can start building your own loom, as well as clear packaging and instructions...
MS1/extra has rev-limiting and a dozen options that the MS2 doesn't yet have
This IS interesting though - These are the things they list as 'new' compared to the MS1 on their site:
24 MHz HCS12 processor,
- Fuel control to 1 µsec (100 times more resolution than MegaSquirt-I),
- Ignition control (full spark timing advance control, dwell control, etc) for one coil/distributor (7 pin HEI for example) and Ford's EDIS systems,
- On-board stepper motor driver for IAC stepper control (this requires a few jumpers to be added on the MegaSquirt PCB to connect the socket jumpers to the DB37 connector),
- Ford PWM idle valve firmware support,
- Built-in rev limiter, either 'fuel cut' or 'spark retard',
- All tables are now 12×12 in size,
- WBO2 AFR target table (in AFR units),
- Independent dual-tables for VE and AFR target,
- EGO feedback in wide-band mode is proportional to the differencebetween the measured AFR and the target AFR, the bigger the difference, the bigger the feedback step,
- Spark advance table can have different rpm and kpa bins than VE and AFR tables,
- 115,200 baud serial interface with MegaTune2.25+,
- CANbus networking
- Barometric correction amount and direction configurable in software, and provisions for:
- barometric correction based on initial MAP reading,
independent 2nd barometric MAP sensor for continuous real-time baro correction, or no baro correction.
-TPS values for open loop and flood clear mode are user configurable,
- MAP based open loop can be set as well as TPS,
- Both TPS and MAP based accel enrichment is built into the code, you can configure the ratio of each,
- Blended Alpha-N and speed density is an option,
- 2 spare I/O lines for custom controls. (This is in addition to 4 lines for Idle stepper control if you don't need this, or the Fast idle solenoid then becomes a spare if you do use a stepper motor.)
Seemed pretty compelling to me - then again, the majority of those things might be something the average user will never even look at, let alone use....but I might play with them.
But if it's the case that the above is incorrect and not quite a true sale, then do say, might be inclined to do something about it

DIYautotune prices are about the same as everyone else. Unless you can slip under the customs radar you have to ad 25-30% for vat and clearance fees. Your issue is support if it doesn't work.
Their list of new features is compared to the fuel only MS1 code, not the extra code which everyone acutally uses. The text quoted is copied from the MSEFI site and was written by someone who refuses to accept the existance of the extra code. I would say it is slightly misleading, but is not technically lying. Jerry sells a lot of kits, but I personally don't think he takes the time to explain the options properly.
For example some of the things Phil runs on his cobra
Launch control? Not there
Flat shift? Not there
Nitrous control? Not there
Everything else bar CAN and stepper IAC is pretty much covered by MS1. Also nearly every V8 in the UK is on MS1/extra so people know that.
Mark: Regarding the restrictors, they are useful on smaller engines, or if you want to mod the throttle linkage for staged opening. They just drop in.
I can't post prices on the forum, it would be inappropriate. But PM me if interested.
