can 20v ecus be chipped

[escortman]

droppin a 20v in the ae82fx, will be doin 2.25in exhaust, and hav seen sock filters put on the quad throttle bodies if i did this i was also thinking of puttin a airscoop just in front of these to get some air in there, but i was also wondering can the ecu b chipped, on trademe i saw a auction where the guy sed toyota ecus cant b chipped, if they can be how much would a slitgh in crease in performance chip cost

[Alex B]

Hes correct, no chipping.

[escortman]

ur kidding is it the way theyr designed or somethign, wat is another option then?

[Alex B]

I dont think the sorce code or equivlent has been released?, A replacement ECU such as a LINK, MoTeC etc.

[Alex B]

Accualy for the basic mods your doing, tru find a sard drop in one, but good luck with that.

[escortman]

ook yeh iv heard theyr lik a needle in a haystack

[escortman]

so i spose another mod could b a port and polish or are the blacktops all ready pretty good

[Mr Revhead]

you can and you cant....
SARD and TOMS can, as they work very closely with toyota, so have access to the info needed. its not just a quick replaceing of a chip either, they have to add another whole level containg several components to the circuit board.

forget the socks. keep the surge tank.
also fit the air box and duct cold air to it. use a K&N panel filter
fit an oil catch can and run it on the best fuel you can get

[escortman]

ok so forget the chip then, the previous owner fitted a pod so if i get a s/s box made up and ducting to the front somewhere wud this b better than the socks

[Mr Revhead]

yes by lots. and lots

[escortman]

instead of the pipe goin in wat bout still doin teh air scoop on bonnet or both

I've got Mine's ECU in my 20v, I've pulled it apart (curiosity), It looks like they removed CPU, soldered the socket/cable to it wich is going to daughter board, wich has normal setup (CPU is separate from ROM chip)... it looks like they kept the stock main board. So it is possible to copy them and "chip it", the daugther board's complicity is average (can be done at home), and does not contain many components (all of them are readily available from shelf).
For gains wich this ecu gives it is not worth it. Tuning practically imposssible. Unless some one has "cracked" the firmware, and has good idea about tuning .. (real time tuning is not really achievalbe with this setup)...

[Mr Revhead]

hehe your too g33k for me. i didnt understand most of that

my SARD one made some pretty good gains. id be interesting to compare them and see if anythings different internally

[escortman]

yeh from wat warwick sed im gona flag doin anythign witht he ecu save money for a turb, can ppl giv me some ruff prices for this converion

[escortman]

yeh if u didnt understand that i had not idea wen he sed daughter board lost me

[Alex B]

If you turbo, youl will need an aftermarket ecu anyway.

[escortman]

yeh i wud only get a aftermarket 1 if i was turboin

[flygt4]

jst slap a evo turbs on au , itll go hard bro , i herd thy will waste any docha turbs out ther. thy cn run 20psi stockers,itll be phat!

[escortman]

o ok but on 20psi the engine wnt last long, i thought wen puttin turb on NA engien boast shudnt go higher than 7

[ROBODISCO_20v]

If you cant find a SARD or TOMS ECU, you could always use a APEXi SAFC2 with the standard ECU to put a bit more fuel in where its needed. You can get upto 10% power increse when tuned correctly.
