Programmable ECUs - the only option for conversions

[DOELLOOS]

Programmable ECUs

A special category of ECUs are those which are programmable. These units do not have a fixed behavior, but can be reprogrammed by the user.

Programmable ECUs are required where significant aftermarket modifications have been made to a vehicle's engine, or where an engine has been transplanted into a different category vehicle such as a 4x4. Examples include adding or changing of a turbocharger, adding or changing of an intercooler, changing of the exhaust system, conversion to run on alternative fuel, and when an engine has been transplanted onto a different gearbox and application other than the original application. As a consequence of these changes, the old ECU may not provide appropriate control for the new configuration. In these situations, a programmable ECU can be wired in. These can be programmed/mapped with a laptop connected using a serial or USB cable, while the engine is running.

The programmable ECU may control the amount of fuel to be injected into each cylinder. This varies depending on the engine's RPM and the position of the petrol pedal (or the manifold air pressure). The engine tuner can adjust this by bringing up a spreadsheet-like page on the laptop where each cell represents an intersection between a specific RPM value and a petrol pedal position (or the throttle position, as it is called). In this cell a number corresponding to the amount of fuel to be injected is entered. This spreadsheet is often referred to as a fuel table or fuel map.

By modifying these values while monitoring the exhausts using a wide band lambda probe to see if the engine runs rich or lean, the tuner can find the optimal amount of fuel to inject to the engine at every different combination of RPM and throttle position. This process is often carried out at a dynamometer, giving the tuner a controlled environment to work in. An engine dynamometer gives a more precise calibration for optimal functionality for the vehicles specific needs. Tuners often utilize a chassis dynamometer for street, 4x4 and other high performance applications.

Other parameters that are often mappable are:

Ignition:
Defines when the spark plug should fire for a cylinder.

Rev. limit:
Defines the maximum RPM that the engine is allowed to reach. After this fuel and/or ignition is cut. Some vehicle have a "soft" cut-off before the "hard" cut-off.

Water temperature correction:
Allows for additional fuel to be added when the engine is cold (choke) or dangerously hot.

Transient fueling:
Tells the ECU to add a specific amount of fuel when throttle is applied. The term is "acceleration enrichment"

Low fuel pressure modifier:
Tells the ECU to increase the injector fire time to compensate for a loss of fuel pressure.

Closed loop lambda:
Lets the ECU monitor a permanently installed lambda probe and modify the fueling to achieve stoichiometric (ideal) combustion. On traditional petrol powered vehicles this air:fuel ratio is 14.7:1. Some of the more advanced ECUs include functionality such as launch control, limiting the power of the engine in first gear to avoid burnouts.

Other examples of advanced functions are:

Wastegate control:
Sets up the behavior of a turbocharger's wastegate, controlling boost.
Banked injection: Sets up the behavior of double injectors per cylinder, used to get a finer fuel injection control and atomization over a wide RPM range.

Variable cam timing:
Tells the ECU how to control variable intake and exhaust cams.

Gear control:
Tells the ECU to cut ignition during (sequential gearbox) upshifts or blip the throttle during downshifts. An ECU is often equipped with a data logger recording all sensors for later analysis using special software in a PC. This can be useful to track down engine stalls, misfires or other undesired behaviors by downloading the log data and looking for anomalies after the event. The data logger usually has a capacity between 0.5 and 16 megabytes.

In order to communicate with the driver, an ECU can often be connected to a "data stack", which is a simple dash board presenting the driver with the current RPM, speed and other basic engine data. These stacks, which are almost always digital, talk to the ECU using one of several proprietary protocols running over RS232 or CANbus, connecting to the DLC connector (Data Link Connector) usually located on the underside of the dash, inline with the steering wheel.

Dit smaak my julle verkoop die goed. Net uit onkunde die vraag: kan mens die OME ECU chip vir van die parameters om n goedkoper alternatief te kry? Bv soek ek nie launch control as ek 4X4 nie, en meeste van die lys goed wat genoem word doen die OME ECU in elke geval? Ek verstaan party ouens soek daai beheer van met die laptop sit terwyl jy 4X4 en die optimale curve te kry en dan weer die te verander as jy huis toe ry op die teerpad maar vir my klink dit na moeite en in die verkeerde hand n gemors.

Dit smaak my julle verkoop die goed. Net uit onkunde die vraag: kan mens die OME ECU chip vir van die parameters om n goedkoper alternatief te kry?

Ja jy kan maar dis definitief nie goedkoper nie. Doe OE ECU opsie is al reeds baie duurder as aftermarket en om dan te chip kos seker omtrent ook so veel as 'n aftermarket system.

Nice article that you found on Wikipedia... Why did you take out the bit about how the Toyota OEM ecu has the capability of reprograming its maps according to driving conditions.. It tells how it is the only standard or aftermarket ecu that has the capability of remapping itself on a continuous basis and this is why a person cant chip the std Toyota ecu’s. I guess the only way a person can describe it is like this
Aftermarket ECU = Programmable but the quality ones come at a price
OEM BMW Ford etc = Pre-set but can re re-chipped
OEM Toyota = Intelligent and reliable.
I personally think it is nice being able to enjoy a car once a mod has been done without having to revisit the whole thing now and then to get it to keep on running well. Would rather do another mod to another vehicle rather that run on the same spot. Everybody can try and mock the oem systems as much as they like but the fact remains that everybody has different requirements. There is a market for both systems so that fact speaks for itself. Lol…
Std ecu R1000 but it is a lot of work with the wiring and one must know the intire system in order to be able to wire it maintaining reliability. But once it runs there is no reason to revisit that side of things ever again.
And if you choose your motor carefully you should get the ecu thrown into the deal free.
If you want engines complete with ecu etc there is a shop in JetPark that has them..
So the cheaper and more reliable way is std management..

I was looking at the prices of the aftermarket thing and its like this….the advanced ecu costs three times the price of the oem from a wrecker

Once you pick everything one needs from that price list it isnt cheap. Actually a lot more than buying a front-cut with a vvt v8

Not sure what the OME system is but even Wikipedia has no detail on that system..
Maybe you thinking of a resister.. So I guess anything is better than that. My preference is OEM…Reason is ..
1.Cost
2.Reliability
3.Time.
4.Parts
5.Support
6.Smoothness
7.Anit theft (Transponder) As we do live in SA…But I guess the older v8’s don’t have that anyway as they are already 25 years old//
There are very nice aftermarket systems out there and there is also a huge market in the racing and dragstrip applications overseas. I went to the show (Cars in the park) and it really wasnt interesting. I was supprised at the quality of work in general.. There were some nice jobs but mostly it was mud.

Hilux4x4 rules apply here, and they are NOT negotiable!!!

You are allowed to appeal this rule in triplicate by no later than 10 February 2010. Your appeal must have 100 signatures of conversion owners who can swear that they have never cheated on their wives or girlfriends, and vice versa.

This is final.

[Scorpion]

Honorable Presidential Candidate of Hilux4x4,

I beg to disagree with your honour, based on the following:
1.) I wish to transplant a Ford 1600 Kent motor into my Hilux
2.) It is a well known fact that the abovementioned motor runs very efficiently on it's Ford IV carburator.
3.) Any sort of electronic OME/ECU/ OPE gadget would be superfluous, based on 2 above.

I just wished to bring the above to your attention and await your answer.

Yours faithfully,
