your right gary ,and there is really no difference in max power between a megajolt and a fixed timing and points ... i was trying to encapsulate what i felt may be the attitude, that would explain the lack of enthusiasm that jean was commenting on ... if you have a look through the site youll see that i personally am well up for a bit of pioneering ,and understand the trails and tribulations paul and jean and rod have been through , i admire all thier tenacity . Sorry Robert, I think I sounded like a bit of a prick there. I know that wasn't your opinion on the EFI developement, you were just giving an example of why people may not be as intersted in the amazing work these lads have done as they should be. I know all about your forays into the unknown. I have only recently started to appreciate the developents work that is being achieved with clutches.

I've certainly been reading with interest. But I don't understand it fully enough to make any worthwhile comments, so I keep quiet and try to get my head round it.

yes as have been said i've had my basic set up now for many years where the 16V lot is a very new thing when you compair time scales, and it's always going to take a little time to get things going with them. But just having a big figure doesn't make you fast. Having a 16v might spin up faster and pull better before the turbo ect, ect, this does and makes for a faster felling car, and it's the above that make them so different and that's why people do them IMO Best 1/4 mile 13.2 seconds @116 mph

another factor is , with matt at 245 bhp odd and then breaking teeth off on 310 ,that gives a window of safe usage ,and if one can get to that window with a carb ,why go to the expense of anything else ? the technical challenge is right on though . I'm sure that there are other TM members who feel the same, but RR figures bear little resemblance with the real world of accelerating up a drag strip or going around a circuit at full tilt. A carb and dizzy can be set up to give the same peak horsepower, but EFI can be used to optimise the torque curve throughout the rev range. Better off the line and out of a corner. That's the real objective. Saul Bellow - "A great deal of intelligence can be invested in ignorance when the need for illusion is deep."

Be it EFI, 16v, the first few turbo mini's. If somebody hadn't made the intial effort and tried something different then none of the advance would have been made and we would all be poorer for it. To me. that sums it up.... When I joined this forum 18 months ago it was because I had decided on a little "project" based on a Mini and when I looked at what everyone else was doing, I opted for the least chosen option because it suits my hobby(s). So whilst last year....... On 23rd Mar, 2009 matty said:
Last year was the R & D year for the bike heads...if the RR day is anything to go by Avon will be ALOT more interesting this year!  .... then this year will be R&D for FI on 5 ports. I doubt I will have anything to show this year, but next year (10) I guarantee I will have a working Megasquirted, turbo'd 5 port. Schrödinger's cat - so which one am I ??? |

As a few others have said, I have been following the EFI threads from day 1, as I find them very interesting.

Personally - I'm annoyed (jealous more like) that I don't have time to be involved in this right now... :( Also, all the stuff about extra boards and what-not is pretty confusing to me - but I feel like asking questions in the thread would slow it down. In hindsight, perhaps it would have made the thread clearer? That's my stance at least... It might have made things clearer for you and for others. as for the extra boards, this is to overcome the deficiencies (for our purposes) of the original Megasquirt design. I intend to look into having a simpler solution and a better packaging. Also, Megasquirt is still the only platform available which has open source code which is what allowed me to create the needed code. And it also means that if, for whatever reason, I'm no longer available, someone can still maintain and upgrade the code. Another good point is that it is part of MS2/extra so will benefit from the upgrades made to the main part of the code. There seems to be an overall feeling that this is too complicated to follow. While it's not simple, you don't need to understand all of the aspects to get the overall picture. How many people understood a turbo compressor map when they first saw it and how long did it take to get it? And do you get the math and physics behind it? Does that mean you can't turbo your engine?

I think it's a great step forward, I follow Paul's thread closely (in fact it's my favourite thread on the site) and I am particularily interested when you have a reply on their Jean, but to be honest I didn't want to fill the thread with silly replys if I can't offer enything. I thought it was interesting that no one else has conributed either other than you, Paul and Rob but then again I guess we are all quietly interested and can't really offer anything.

Again I fall into the category of following the development with great interest but I haven't commented to date as I don't think I could really contribute anything of any use. Isambard Kingdom Brunel said:

Part of the problem is that this has taken a long time to develop.

..... as for the extra boards, this is to overcome the deficiencies (for our purposes) of the original Megasquirt design. I intend to look into having a simpler solution and a better packaging. Now...... that would really appeal. I'm slowly buying the bits for a second MS but based solely on your 4 driver design and am horified by the amount of wasted space on the V3 board there will be. The peak and hold chips on your board take up far less space than the MS 3.0 design and if I bought a kit, most would go in the bin.... The daughterboard is available to purchase by itself at a reasonable price, and it seems that your code only really requires that little duaghterboard (slightly modified for staged injection) and a few other parts, specific to the siamese code, and the (few) inputs required. Two weeks ago (when I was ordering the few extra bits I needed to complete the JimStim) I was seriously considering making my own mainboard....... I've made PCBs myself in the past but, because of the limited facilities we had at work, they were limited to 2 sided and no fancy silk screen or solder protect.... but a "prototype" can be bought in the EU for quite a reasonable price if I supply my own gerber (or other compatible) files. The only thing that concerns me from someone making their own specific PCB (for their sole use only) is just how far B&G's intellectual rights prevent it. Rod.

The other thing to consider is that the EFI is a bolt on mod. No need to remove the engine. for a great number of people I think this would be the asset that will see lots of people move to Efi. For people like me it would have to be an out of the box bolt on and with the manifold it might be harder. I don't know what effect a different manifold would have on the setup as like most its loads to get your head around. With the risk of being flamed isn't this what the Canems ECU is saying they do.. I run a supercharger and I don't care the TB is on the wrong side.

I could not get it to give close AFRs, so I don't know how they can. Maybe thats why they have never published dual wideband data. The latest code is now a refined version using a cam sensor. More like the MPi setup but with bells and whistles. Saul Bellow - "A great deal of intelligence can be invested in ignorance when the need for illusion is deep."

With the risk of being flamed isn't this what the Canems ECU is saying they do. I think it's a valid question and the answer is no. What they have is much more limited. And if you look at their own graphs, they show that they cant' achieve the same AFRs for the inner and outer cylinders. Paul S has been able to do it through a very thorough testing process with the help of the code which does allow the use of a cam sensor to tailor the fueling that each cylinder requires. The Canems method (which, by the way, I had coded long before they had their ECU out) cannot do that because the don't have the code to use a cam sensor and are limited to the same pulse width for inner and outer cylinder. Moreover, they can't move the pulse angle position independently for the inner and outer cylinders. Jean |

This will sound cheeky/sad, but at the moment, I reside in the catagory of "people that would happily implement your hard work once the problem has been solved, but havent got the knowledge to help at the moment"

Echoing somewhat what joeybaby has said, I think once it is available virtually as an off the shelf option there will be a raft of people giving it a go.

Have a very keen interest, and have been following the thread since the start, its the first thread i check every time i log in here. Even though no a-series will ever grace my engine bay again! however, dont want to contimainate a gloriously fast moving and technical thread with my drivel, so leave it out :) the close AFR's is a true milestone. hats off ! turbo 16v k-series 11.9@118.9 :)
