albundy68 Posted January 20, 2003 Share Posted January 20, 2003 anyone know if the com port (for the ECU) on the jap supra (97) is OBD2, coz if it is theres the possibility of gettin hold of a really cool chip (from superchip) that is self programmable, so you can have super settings for racing, econo settings for... (umm, if youre giving granny a lift home), and still be able to return to normal settings for MOTs/insurance inspections (nice since the insurance mark up on superchips is usually sky high), and you can get it to shut down with a code, so extra sercurity, sounds pretty good if it could work on a supe....

Guest Terry S Posted January 20, 2003 Share Posted January 20, 2003 The later US cars are definately OBDII but I have never heard of this wonder chip. I would be very surprised if you could mess with the stock settings. There are Company's that will reprogramme them, but not in the way you are suggesting, but who knows!

albundy68 Posted January 20, 2003 Author Share Posted January 20, 2003 yeah seems pretty, high tech, the fella that i was talking to it about, (not sum bloke in a pub, a fairly clued up fella, so there could be truth in it), has left, but as soon as i can get hold of a link or anymore ill post it, should be in the mornin, oh and thanx for the reply terry, i was starting to think everyone was ignoring me, no replys on my turbo timer thread, then a while before any on this, Quote Link to comment Share on other sites More sharing options...
paulrenn Posted January 20, 2003 Share Posted January 20, 2003 Let me know. Mine's an ODBII ECU, late model US. Not sure if Jap/UK specs got it or not. Quote Link to comment Share on other sites More sharing options...
THOR Racing Posted January 20, 2003 Share Posted January 20, 2003 You can tell if it's OBDII by reading the name printed/embossed on the diagnostics connector. This is located to the right hand side of the steering column, towards the bottom. It's like a D-type shaped connector. It'll have a plastic cap over it with OBDII written on it. This cap pops off to reveal the connector. I think the OBD changed around 97 period so you may or may nor have OBDII. Don't be fooled by OBDI, it's completely different. OBDII is a proper protocol standard but OBDI was just a serial line pulsing up and down. Which is what most people here recognise as it also flashes the Engine Check light to indicate the fault code. OBDII has one standard of communication but three physical layers to choose. Sorry but I cannot remember which physical layer Toyota use but.... J1850 VPW--The connector should have metallic contacts in pins 2, 4, 5, and 16, but not 10. ISO 9141-2--The connector should have metallic contacts in pins 4, 5, 7, 15, and 16. J1850 PWM--The connector should have metallic contacts in pins 2, 4, 5, 10, and 16. Picture of the connector is attached. The following is a good site to learn about it. http://www.obdii.com/ Specifically for the diagnostic trouble codes... http://www.obdii.com/codes.asp Regards Pete Quote Link to comment Share on other sites More sharing options...
roboldham Posted January 21, 2003 Share Posted January 21, 2003 Good reply Pete! So - are you gonna ship a lead and code so the tweak heads can play ? R Quote Link to comment Share on other sites More sharing options...
THOR Racing Posted January 21, 2003 Share Posted January 21, 2003 are you gonna ship a lead and code so the tweak heads can play Sort of, I am doing a OBDII diagnostics scanner. This will clear DTC and allow you to view active sensor information in almost real-time (as the vehicle ECU actually controls what you see so you're never to sure when in time the data changed) It won't be able to tweak values, mainly because I haven't figured out how to. I suspect it's just finding the relevant code to send and then changing the data applied. So if anyone knows more I'm keen to learn.

Guest Terry S Posted January 21, 2003 Share Posted January 21, 2003 Isn't there a Techtom or whatever it's called that does this now for both OBD1 & 2?? It will not let you alter settings though AFAIK. Quote Link to comment Share on other sites More sharing options...
albundy68 Posted January 21, 2003 Author Share Posted January 21, 2003 well, superchip who are supposedly going to reliese this product dont have an official statement on it yet, and i quote "no can do unfortunately, it's not released yet and the info / link that we've got isn't allowed to be generally released..." my mate probably got the news from the focus forum, not shure if the link will be on there, but they seem to be a bit tight with it! but like i said before he's a pretty relyable chap, when i get anything more ill post it up!
