Hey acesniper i remember sometime last year you were telling me that your factory 20v computer was chipped or something. I was wanting to know a bit about how that worked? who did it? Do you know who does this kind of stuff? Is it pricy? In comparison to the a non modified computer how does it rate etc.

Thanks mate.

it'll be easier if you jst drop him an e-mail or pm and correspond directly.

from what i've heard there is not much point in chipping a toyota ECU as you do not get much of a performance increase out of it.

[spencer]

I would like to see how this is done as the chips are soldered in place

That's not a problem, when we chip Mitsu ECU's we just unsolder the factory (e)prom, solder a socket into its place, and then stick the original chip intothe socket until we get round to writing a modified one.

[spencer]

yea but I didnt think anyone did custom ones for toyotas or we would all be lineing up

[spencer]

yea realise you could unsolder but I didnt think anyone did custom chips for toyotas or we would all be lineing up

[FLAWLES]

i thought toy ecu r to brainy and pick up on this type of stuff

but y pisss around chiping y not just piggy back the ecu????
i have done this and would reckomend it to any other toyota owner

[IH8TEC]

piggy back with what, can you give more details? what functions does this piggy back perform

[corollamadness]

Yes please explain i would like to hear about this. What unit did you use and what does it control.

[Silent Knight]

piggy back is basically just the same as a stand alone fuel management system.

[IH8TEC]

such as megasquirt, or injector link type things

[Silent Knight]

it's basically a plug in ECU but without all the functions of a full blast A/M ECU. You can pick up a small piggy back plug in unit from Greddy for about $250 excl. harness.

hey, sorry iv not been on for awhile,
for the chip the main controller has been unsoldered and a plug-in system soldered in its place (the chip can plug strate into that if u wanna unchip it, but ontop of that is a 2nd board with a rom and cpu type of setup with the factory controller thats about it... no speed limiter an rev cut at 9, there is 3 solder bridges/switches dono what they do tho an the speed cut chip is removed from the main board.... when i can ill get a pic up

[Bling]

an the speed cut chip is removed from the main board.... when i can ill get a pic up

no speed cut eh.....sounds sweet....of course it would be no use to us

IT PIGGY BACKS with your standard ecu " just bridges into the standard ecu wiring "

from the one that i have you can adjus fuel settings and igntion timing and if you are running a turbo set up it can be set up for adjus boost

my uncle and steve murch desgined them they are really pob in the states www.powerhouseracing.com

some poeple have said " this is a quote " they are better than links
this is a morjority

as for the greedy/trust ecu if its the E-mangement one there now about $650 to $900 pending on wht set up u go for and they do not have a heck of a lot of tunibilite
wot i think anyway

hey ace sniper can you slap it on a dyno and adjust mixtures?

ummm no not that much...you might be thinking of the full blast stand alone unit...i'm jst talking bout the little plug in piggy back. dsnt do much but a lil bit of tuning.

[RedMist]

You can't adjust a piggy back fuel / ign curve without reburning the EEPROM. It means you have to dyno the car, test the mixtures for your specific modifications, modify the code, remove the EEPROM, burn the EEPROM, dyno the car, test the mixtures for your specific modi.... long lengthy task... and that's if you have reversed engineered the code and know where to alter the mixtures. Unless someone has already created a piggy back EEPROM and is willing to give you their rendition of the reverse engineered code it's a total waste of time. Even then I wouldn't go there unless I was prepared to spend countless hours modifying the existing codeset. Existing piggy backs are set to a specific fuel / ign curve and burnt that way, your car doesn't match that curve... TOUGH!

I can program in Motorolla Assembler, however I chose to go Link LEM.

[AceSniper]

hey ace sniper can you slap it on a dyno and adjust mixtures?

I doubt anyone could program the rom thats init altho it can be pulled so could be swaped or what ever with a newer chip, from what iv found this sard add-on was made for other cars to and its been made to run best with bolt-ons like intake, exhust, headers... its not the choice if you want to go hard... but if you want something hassle free its good.

hmm at one stage "hare" was selling a TOMs AE101 ecu on here..... does anyone know who got it? and what kinda things it does?
