can bike throttle bodies run on standard managment on a vts?
If so which ones, and what gains would be seen,

Also Agree with raunchz. Even if you did wish to stick with the original ECU you would have to have it so extensive modified to work at all well I cant see why anyone would do it over a stand alone system. Standalone is simple and very easy to reprogram if ever required.

Very true and its not cheap and a long way from the standard item when he is finished

Got my popcorn at the ready for this one
But personally id not be running an OE ecu with my car and be limited to just one person being able to map it, and the joy of a decent standalone is you can save the map on to your pc so if you ever have any hardware faults you dont loose the map aswell. |

I am a bit confused as to where your coming from now. As my point was it will not run on a standard management as it has to be modified to work at a not so insignificant amount. When I was original quoted for the work I thought I may as well go stand alone as it did not work out much more, was much simpler to have mapped later down the line, could migrate to other engines if required and the options from stand alone units were far more comprehensive. The proof is in the pudding as it ended up the strongest engine on the track so was very happy with my decision.

its 16x16 ross. the geographical thing is an issue but with chipwizzards down the road from myself and seeing a car develop over 200bhp i would consider it if taking my car further. chipwizzards are even working with ricky-p to map a standard ecu for boost.
|

Ah okay, if you're local to Chipwizards then it does seem like a good solution - any idea on a rough price ?
So effectively it does become a standalone Ecu, that's cool to learn ! I wander what sort of software is needed to do this sort of thing with the OEM Ecu? I would imagine you are effectively reading and overwriting some sort of chip in the Ecu with new parameters? |
|
depends what you mapping the OE ECU for. i know the basics of mapping them to run bodies but i dont know how you would go about mapping them for boost if im honest.

Can i ask the advantage of a oem ecu map over easily re-programmable aftermarket Engine management. Especially as oem ecu's are atleast 7 years old now.....Unless its a replacement unit. So effectively, is equal to s/h standalone unit, which generally are cheaper... |

taken from what wayne said on here i personaly understand very little of though lol. Someone did ask what the map resolution of the stock ECUs were, I suspect trying to imply that it was in some way inferior to a particular 'nameless' system. Well I can tell you that the main tables are 11(load)x24 or 20 speed sites, depending which system you pick and they ultimately have 16-bit value resolution (each step being finer than 1/65000th). This compares with 12 load and only 12 speed sites (not enough for a high-revving engine) at a miserable 8-bit resolution (with steps no finer than 1/256th) which is too clumsy to be acceptable for me, which is one of the reasons why I won't do the 'nameless' systems any more. That reason plus miserable reliability issues. |

firstly the oem ecu is at least 15year old design --nothing wrong with it.
but there is no way you can have the flexibility of a stand alone you cannot remap an oem unit to do same job as a stand alone ,purely and simply because you cannot get at all the parameters in the oem ecu . it is a half way house at best . It can work fine on some limted conversion of the program it was fitted with from factory . but it can in no way be considered a direct comparison to a stand alone ecu. anybody that argues otherwise is flat out wrong .there is no other way to put it. At some levels of tune --it may work out every bit as good as a stand alone ecu -but once you start changing components the advantages become disadvantages-so for any serious tuning its a poor choice due to its inherrant limitations,because it was designed for a specific car + state of tune |

Can the ignition and injectors be that accurate to take advantage of the 1/65000th step? When compared to 1/256th it sounds hugely finer but would this give a 'better' quality map, and wouldn't mapping take a lot longer?
Not really aimed at you webby, just a general question, but I don't know how 'fine' a map the car can use and be advantageous over a 1/125th ecu resolution. Would the hardware (such as injectors, crank position sensor etc?) be the limitation to this? Sounds very interesting though, is cool to find out some info about the oem Ecu ! |

i really dont know ross im afriad, i am putting in some time at uni with the racing team and i will be learning about mapping and ecu's ect as it really does interest me. so i will report back in a few year lol.

Same old discussion that's happened a dozen times before - YES it can be done, why don't you go standalone, what standalone you got, Predator, oh I know some huge secret about them, let's keep the discussion polite, YES it can be done.
I wish I was in on the big secret!! Andy |

its good to have a conversation about a subject rather than everyone going mad including myself.
if i still had my saxo this is how i would do it; if the car was on bodies for example and it was a weekend car used mainly for b blasting and the odd RWYB day then i would get the standard management mapped. if how ever the car was a proper serious track car competing every week in the race season i would go for an after market ECU. this is because as someone mentioned, the technology in ECU design has moved on from wheh the saxo was designed a good few years ago now. then the technology stopped developing as the car ceased to be in production. where as after market management continued to develope until present. i suppose it all boils down to what your car is going to be used for and if your happy with it thats all that matters. i know pretty much everyone who has a predator ECU designed by andy is more than happy with it and give him consistently good reviews, and at the price they are they are worth every penny IMO. also i think that the standard ECU is very good at being able to adapt to bodies for example for the age of the technology, so its not got to be massively expensive for you to run bodies. obviously there are very very expensive ECUs out there that cost well into the £1000s but as i mentioned earlier it all boils down to what you personally are wanting the car for and what use its intended for. |
