what I found after abit of testing was engine drove better when cold well this is normal with most enignes but once my 1uz got hot and I used full throttle it went worse than half throttle u should really put an air fuel sensor a proper accurate one not a gay ass fking autometer crap...

the only prob u might run into is most air temp senders are plastic around a metal sensor coolant temp senders are brass so they very slowly change resistance air temp senders change quick due to air temps variations I have seen in the early days bosch air temp senders that were brass...

hey George the ecu part number is 89661-50590 it looks same as one in your non smart pic but don't know why it has an external immob ecu the wiring from usa model matches close to this but it has a big chunky ignition switch and plastic key with no metal part of the key going by diagrams...

hey George can u bypass the immob in this gs430 ecu if I send you the ecu by the time I buy another immob ecu from ebay and program it its easier to send to you this ecu is different to the 1uz vvti as it has external immob ecu so I cant use my 1uz vvti bypass module on it as the immob...

thanks I have 10 dvds with all the data from usa cars and one of them matched up

yer I think it is has a huge ugly ignition key funny looking ill try sort it out once I finish these 5 gm 6lt looms

I just compared this ecu to your pics and its an early one looks just like the 1uz vvti and im pretty sure when I looked at key it was a 4c transponder so ill try my 1uz vvti bypass module on it

hey George this ecu has an early part number maybe its not a smart model its just got a plastic key no blade so maybe it just has electric steering lock

its missing the immob ecu the immob ecu for smart key is bigger so im just going to buy a non smart and program it just need to save up for my Toyota flashing cable so I can reset Toyota immob ecus

I'm doing a late 3uz loom at moment with smart key so I'm pissing it all off And just buying an early immobiliser unit and programming a chip to it

just buy the spittronic aftermarket loom and get a local tuner to tune it for u that way u don't have air flow meter and o2s to worry about it just wont control the auto if u want to keep auto then do like zuffen said and google stuff buy a printer and print off heaps of pages and organise...

there is afew brands of gps modules in usa and china but since I try to use high quality stuff I buy some modules from my supplier in Australia much better quality but they are double the price like most things in life u get what you pay for

just buy a gps speedo pulse generator

unfortunately it takes a couple hundred post count in your info before people realise this

maybe just take it to someone who knows what they r doing and stop staring at the stars when u remove auto the engine will not crank so u have to join two wires on the inhibitor plug one is the sta and one is the nsw once they r joining it means the engine ecu thinks its it park or neutral...

cut the sta and the nsw wire from the ecu and see if that makes a difference if not then just fit the auto back in surely theres someone over there u can take it to to fix it

never had any problems wiring them up in manual form did u join the start inhibitor wires together how about cut those wires and do not have any wires from auto connected clutch start car as without those wires connected it wont crank then road test it see if problem is still there

who needs diagrams just do more of them and everything will be remembered in your head I don't think its the lack of documentation I think its the lack or using good electrical stuff unless u do this day in and day out most backyarders just goto supercheap or repco to get bits n pieces...

snap on modus hanatech ultrascan

2 negatives here in Australia is price and if its in US dollars we get shafted even more the other is a lot of guys want to get rid of the air flow meter if someone was smart they would make adapter kits to make the megasquirt plug into some 1uz ecu plugs another thing like zuffen said...
