In this case we just got :
Log: ^@Sec=00913
instead of
Log: Sec=00913
in the log file but it could have been worse.
That should clarify it pretty well :-)

only new cars in UK with cable throttle now will be the very small sub 1000cc town cars .everything else including diesels have some sort of FBW--GrowlingandBiffo wrote:Are any new cars still made with throttle cables?
The only Fly by Wire safety issues we can recall are Volvo, in the US of A when their cars suddenly took off and hit something but this was traced to pilot error.
If you try and "blip" the throttle, when stationary, in a modern lorry it will not rev very high. This stops bored and stoopid drivers from pretending that they are racing..
Perhaps all ecu's will have this as an option so you can let the kidz borrow the car, or will it be std to reduce emissions, and save fuel.
Race cars are faster with Fly by Wire, which is why they stated to use them..

LOL, a strange concept indeed to limit air to a diesel. I hate electronic diesels, it removes their very best feature : durability in ANY environment.johnd wrote:everything else including diesels have some sort of FBW
I'm not sure what you think I am trying to do, but I am trying to provide a system that people in poorer places and students etc who aren't lazy, but are poor can use to get the best possible performance from their engine for the least money. I'm not much interested in helping corporations make cash on it supplying it to owners of high end modern cars. Most engine swaps and EFI swaps are on older cars and those with std throttles anyway. If the high dollar boys want FBW, they may pay for it :-) The point of this site is the DIY part. That includes the boards, assembly, wiring, etc etc etc. Do It Yourself at home, in your drive/garage, on a budget at night while studying/working etc. That is the spirit in this project. Some people miss that point. Another is adapting and engineering around OEM monstrosities that are supplied on modern vehicles. Adding a throttle is nothing to a true blue DIYer, at least not in New Zealand it isn't! Things certainly are a bit different here though, I've stayed here long enough to know that now.It is rumored that ESP will soon become a requirment for all EU spec cars ,and that cannot work without FWB.
this is why i am suggesting you think about it from the beginning ,even if is not used ,as all engines have or will have it soon ,and cost to buy a t/b and make a cable set-up in a car not meant for it somehow goes against what you are trying to do -- So please include an output to run a FBW
This is a little off-topic. Are you talking about 'pumping losses' by having a throttle, Fred?Fred wrote:LOL, a strange concept indeed to limit air to a diesel.

No, I mean the ability for an old style injector pump traditional diesel to run UNDER WATER with only a tube of fuel and a tube of air (no battery power at all). I have had my life saved by this once, and in any serious situation (boats, commercial vehicles, off road vehicles etc) it is absolutely invaluable.MotoFab wrote:This is a little off-topic.

Oh, I get it, that level of durability.Fred wrote:No, I mean the ability for an old style injector pump traditional diesel to run UNDER WATER with only a tube of fuel and a tube of air (no battery power at all).

I imagine the manufacturers are using them to avoid pumping losses, however that is annoying too, diesel engine breaking is a fine feature that should not be removed by choking the air supply.
the way the world is going now and the way car values drop there are so many perfectly good modern engines which give good power and economy sitting in scrap yards ,lighter than old units better power in std formIt's a minority thing anyway, so it has to wait for everything else that WAY more people want like idle and boost etc.
Cheap is only one factor when choosing an engine. I prefer to choose based on performance capability and strength also. Most modern engines have pencil rods and are built with slim margins to make the power that they make and little/no more. I'd take a 1988 - 1998 engine over most modern stuff anyday. They were building them flowing well enough then, and still strong enough to take a beating. Modern engines are good for stock form and emissions and little else without major work. This isn't specific to any given manufacturer or country of origin either. All of them have gone that way for legislative reasons. New != Good.johnd wrote:the way the world is going now and the way car values drop there are so many perfectly good modern engines which give good power and economy sitting in scrap yards ,lighter than old units better power in std form
far cheaper to fit one of these than even rebuild an old engine .
Its far cheaper now to get a good s/h unit than rebuild most engines --thats where I,m coming from
No, it's poetic justice. Why should someone with a pocket full of cash benefit from my work when my account has 5 quid in it and I'm working for free? IMO they shouldn't, if they can afford to pay, they should crack out the wallet and stop being tight. I do LOVE the way well educated POHMs speak (apparently a minority) and aspire to speak the same way, so in that respect I am a snob. I'm a snob when it comes to tech too, only the best will do. However I loath the attitude that comes with the good manners and elocution lessons etc. The only thing I loath slightly more are all the uneducated POHMs that can't speak english as well as this middle class kiwi ;-) Poor form old chap, as it were, etc, old boy. So, yes, reverse snobbery if you like. I'm OK with that, are you?you are almost sounding like you would begrudge someone with a newer car fitting a diy unit to to --is this reverse snobbery?? LOL..
= Pencil rods.double vanos
This is not a realistic limitation unless the person making the decision isn't aware that for 5 quid they could have a laser cut adapter to a reasonable sized throttle of an older engine. Vanos etc is easily controlled.etc that stops them being fitted in kit cars + home builds ,cos the thought of buying a GEMS,or MOTEC etc to run them + costs of someone to set them up is too much .
This is possible. I said I want an open platform for DIY type people to be able to build and modify in any way they want. What I meant by that was that I wanted some good functional firmware that does the basics VERY well and can easily have cherries added on the top at a later date that is licensed under GPL such that anyone can build hardware for it. This would mean free hardware designs, and it will also mean cheaper commercial hardware designs because of competition. The fact that my code is commented and structured and readable means anyone can modify it with relative ease. This makes good engine management accessible for those who aren't on the right side of the Buckingham Palace gates.I maybe have misinterpreted your mission statement
Firstly, what exactly is wrong with MS in your eyes? Secondly, it WILL be able to compete with any similarly speced ECU and give them a good thumping in many cases, however that is not the goal. There will always be a MOTEC that does it a little better. You need to aim for where you want to aim for, not where the jones are at. The goal is to satisfy MY needs and the needs of the sort of people I care about. Much less the sort of people that as Pink Floyd put it are "riding the gravy train".I don,t see the point in making another megasquirt type thing --when with the same effort you could be making something that would conpete with any ecu system on the market ,and yet have it as a diy unit
I bet you think the ford pinto engine is a good engine . name me a good engine from that eraCheap is only one factor when choosing an engine.
