ok people i got the new jaycar catalog and saw something youse might be intrested in..
a fuel controller ecu...and handset for total of $140!?
controller looks similar to a microtec hand controller
catalog number for the digital fuel adjuster is KC-5385
catalog number for the hand controller is KC-5386
and ebc for nyone intrested is cat no. KC-5387
what use recon?
Jaycar website www.jaycar.com.au
There not here yet...
hence the "coming soon"....

is a device to modify the input signals to the ECU, like AFM/MAP, temp and O2 signals...
it migh be interesting to adjust for small changes, and for larger changes to modify stocko ECU to be used with larger injectors..
it is not a standalone ECU, it is an input signal 'conditioner'
and yes it does look interesting..
but so does a Megasquirt standalone ECU for $180

i agree with u stewart megasquirt does have excellent capabilities like especially wideband o2 sensor capability....but...isnt that 180 us dollars?
approx 300 aud with postage?
and uses a laptop for programming?
(correct me if im wrong...ive got no experience with the megasquirt!)
wheras for $140 u get this with a controller which u can read the data off as well as program...std ecu parameters can also be kept (cold start enrichment and other things. for prople with a turbo car the handset is also used for the boost controller and can be used for extra injector kit as well) which means dyno time is at a minimum (hence cheap dynotunes) much simpler to install....anyone can do it....a few wires....one major drawback will be if it doesnt have a tps connection...(which it i think it doesnt  ) but for a cheap fuel controller i think it is a good thing. my friend has a blits safc which works the same i think but also has tps sensor for load as well...sinch for connection...tuning... and works well (ca18det 14psi 161rwkw and runs smooth)...i gotta find out if it has a tps input output.

it doesn't have wideband O2 support. it has narrow band support and does closed loop.
it's US$140, OR is AUD$180 in one of our australian group buys (which i happen to host.. we are completing our fourth so far with over 60 MS's provided)
you can buy them from Glens Garage for US$140 +post.
yup, uses laptop. or Megaview
the megasquirt has true datalogging capability, only limited by your laptops hardrive space.
TPS is not used for 'load sensing' for most factory cars. the load sensing comes from AFM or MAP sensors. the TPS only provides accel and decell info for enrichments, and also provides 'flood clear', turns O2 closed loop off at certain throttle position, etc etc
typically all you need to adjust to change the fuelling is the MAP/AFM response, since that is the primary factor in fueling.
using alterations in temp and O2 feedback is bogus.. keep it in the warmup stage, and the ECU will probably not enter closed loop. use O2 feedback to richen it up and it will go lean at WOT.
many pros and cons for 'fooling' a stock ECU (particular for stock motors ) but if you understand it, it does have a time and place.
as i said before, i think the best use for these 'signal modifiers' is when larger injectors are used (since this allows greater fuelling capacity) and you can use the device to reduce relative fuelling so that the rest of the table is ok...
you will need a dyno tune even moreso with these unless you know exactly how the stock ECU works.. woudl suck to have an unexpected leanout..
