Gazboy Posted April 15, 2005 Share Posted April 15, 2005 Just done a search, but apart from the fact I'm crap at searching and googling- I couldn't find a definitive guide (ie everyone agree's 100%) about making the Supe go quicker (both in a straight line, and around the twisty stuff). I've seen the sticky that Aerotop Dave satrted, but that seems to have died a death last year. Anyone got an idea like this in the pipe-line? I wasn't thinking about BPU stuff, as most people agree on more or less the same stuff, the only argument is a EBC vs a restrictor ring- I was thinking more about "what next after BPU?". Also how could I have a nice ride quality (ie no crash/bangs) without turning it into a Lexus LS430 in the process. Help me I'm clueless. (I could use that as a sig???)

JohnA Posted April 15, 2005 Share Posted April 15, 2005 ...I wasn't thinking about BPU stuff, as most people agree on more or less the same stuff, ... I beg to differ mate. Ain't kidding either... I will make this Supra guide part of my site, eventually, but it will take some time until I build up know-how on Supra specifics. Until then, try http://www.Mkiv.com and the 'tech' bits of this site. Lots of info in past threads. Link to comment Share on other sites More sharing options...

Gazboy Posted April 15, 2005 Author Share Posted April 15, 2005 What's your budget, how fast do you want to go and where do you want to do it? It's an open ended question for anyone. ie- I would like a fast road car, but caperble of 2 mile runway blasts 3 times a year, I want BMW M3 style ride quality, I want to retain the sequential turbo system. My budget is a little bit at a time, even if it's more expensive than doing it all at once (doncha just hate doing up houses?). I would like bellyfuls of torque at low revs. Others may want a quarter mile drag queen, or a stripped out track-car. Biggest queery for me is engine management. It's a question for everyone, not just me. Link to comment Share on other sites More sharing options...

Gazboy Posted April 22, 2005 Author Share Posted April 22, 2005 May I ask a silly question? I mean REAL silly, as in "I can't believe he just said that" silly? Look at the engine pic on the ebay auction: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=4521779913 On stockers there is a afm sensor assembly between the air filter and the turbo, but this car has nothing like that, nor an air filter- could someone explain to me how this works without the afm, and how come the turbo isn't reduced to shrapnal without the filter? Sorry for being dumb, but I just gotta know! Link to comment Share on other sites More sharing options...
Alex Posted April 22, 2005 Share Posted April 22, 2005 AFM's are only present on UK/US and VVTi models - the J-spec uses a MAP sensor in the intake manifold. This car, along with many other highly modified US/UK/VVT-i Supra's has been modified to use MAP only based mapping. The MAP sensor is used on ALL models but serves a different purpose from regulating the fueling on the UK/US/VVTi cars. An aftermarket ECU is the way to remove/replace a MAF.

Alex Posted April 22, 2005 Share Posted April 22, 2005 Right in which case the MAF is irrelevant. You're MAP based and have nothing to worry about. An eManage piggyback or AEM plug and play ecu is what you want. Mapping is a bit of an art and fairly impossible to explain on here. So if you ever go for an aftermarket ECU you will have to add in mapping costs as I wouldn't recommend anyone just try and do it. A piggyback ECU "tricks" the stock ECU into doing what you want, reduce or increase fueling at a certain load. The full replacement ecu needs to be mapped from the ground up but does have more features usually and will allow you to map more accurately. But FWIW, Different aftermarket PIGGYBACK ECU's can remove the need for a MAF by basically ignoring it. It takes in the signal from the MAP and sends that to the ECU (disguised as the MAF's signal) fooling into thinking the MAF is there...a full aftermarket replacement ECU just won't need the MAF as it will be part of the setup of the ECU to say whether you are using MAF or MAP.

Gazboy Posted April 22, 2005 Author Share Posted April 22, 2005 Ah, I see! Where on God's earth can you get a AEM/Motec or an E-manage mapped? Could DMS (do lots of 996 turbo mapping) for example map it, or does it require specific Supra knowledge? Link to comment Share on other sites More sharing options...
Alex Posted April 22, 2005 Share Posted April 22, 2005 Knowledge of the product is all that's really required with mapping an AEM as it plugs into the stock loom. So if you gave them the software and the spec of the car before going there they could at least become familiar with it...the AEM is the same as the GEMS (British) ECU just rebadged and only available in the flavour we need from AEM AFAIK. The eManage and MoTeC would both require re wiring - you can buy from http://www.mohdparts.com a plug in wiring harness for the eManage. The MoTeC is the hardest and if they can do them then they should be able to sort out the other 2...but it may take them time. I'd recommend you search to see who has mapped what. If you can get over to Norwich and get an eManage Ian C will map it for a very reasonable price. I'd not like to recommend anyone else as I've not been to anyone else. But there are individual's on here like Wez and TLicense who are very familiar with the AEM... Link to comment Share on other sites More sharing options...

Gazboy Posted April 22, 2005 Author Share Posted April 22, 2005 While we are on the "educating Gaz" theme, I saw this in the single pro v cons thread: "Also what ever way you choose to go, id say a wideband O2 sensor / gauge is a must. The AEM is good as you can log its output." What does the W/B replace? Link to comment Share on other sites More sharing options...
