skyludeboy Posted May 9, 2010 Share Posted May 9, 2010 At the moment I have a 2jzgte engine with 6 speed box fitted to a jzx100 chaser, running hks t51r turbo kit, hks cams, tommie fuel pump, tommie fuel pressure regulator, intercooler, oil cooler, koyo rad. All the spec was done in japan, Cars making 453bhp @ 1 bar What I want to know is can I have the stock ecu mapped? or do I need to go for a power fc what are my options, because at the moment the car has a stock ecu and some wires comming off the stock ecu going in a small plastic box which I believe might be some sort of jap ecu chip (will take some pics). I dont think any one might be able to map this. also have attached a dyno graph- advice welcome and appreciated as Im new to 2jz tuning and dont know the do's, don'ts and where to start. Many thanks Asim Quote Link to comment Share on other sites More sharing options...
skyludeboy Posted May 9, 2010 Author Share Posted May 9, 2010 just noticed that the picture of the dyno graph is really crap will get it scanned in a bit Quote Link to comment Share on other sites More sharing options...
Dave17 Posted May 9, 2010 Share Posted May 9, 2010 Nope, can't be remapped, you need a piggyback or stand alone ecu Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted May 9, 2010 Share Posted May 9, 2010 Do a search dude. The box is probably an FCD. You will need an ECU to exploit it fully. Quote Link to comment Share on other sites More sharing options...
tooquicktostop Posted May 9, 2010 Share Posted May 9, 2010 T51 is a big turbo to be running without fuel management, I would get this sorted quickly, are you running stock Jspec injectors? I think a full spec list and some pictures would be useful I feel a big bill is on the horizon Quote Link to comment Share on other sites More sharing options...
skyludeboy Posted May 9, 2010 Author Share Posted May 9, 2010 Im not sure on the injectors what colour are stock injectors normally? Quote Link to comment Share on other sites More sharing options...
Nic Posted May 9, 2010 Share Posted May 9, 2010 The stock ECU needs replacing with a standalone ECU and properly mapping. I can't believe it's been run on a dyno with the stock ECU, were they monitoring the air fuel ratios, it could have quite easily gone ? It really need taking to a 2JZ specialist and sorting out, don't drive it until it is. Quote Link to comment Share on other sites More sharing options...

skyludeboy Posted May 9, 2010 Author Share Posted May 9, 2010 just checked injectors are grey so they are stock, how many posts do i need to place a post in the wanted section i need some 800cc injectors and a suitable ecu can some one post an add for me?

You need to take a step back mate, get the car to a Supra 2jz specialist and get them to check the car and the spec over for you, it may have other issues than just needing injectors and an ECU The HKS T51 is a very expensive kit and it is a surprise that it is fitted to a car with such poor thought, does the car have any additional injectors in the intake pipe as this is sometimes a crude method of adding fuel I am amazed a garage dyno'd the car in this condition, the AFR's must have been shocking Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted May 9, 2010 Share Posted May 9, 2010 Maybe the car was raped in Japan before it came here, had a proper ECU/injectors before it was sold? Anyway yes get the car to a proper tuner because Im betting your AFRs are way lean with that power and stock fuelling Quote Link to comment Share on other sites More sharing options...
skyludeboy Posted May 9, 2010 Author Share Posted May 9, 2010 yep I also think it may have been raped in japan too Quote Link to comment Share on other sites More sharing options...

You need to be a full member to post in the classifieds section and access other sections. See HERE I would go with 1000cc injectors, the T51 kit you have fitted is good for 800+hp, but needs the fueling and ECU sorting out before being started/driven. Any pics of the engine bay you can post? Quote Link to comment Share on other sites More sharing options...

trinitom Posted May 9, 2010 Share Posted May 9, 2010 this just proves how good the 2jz engines are, running like that on the dyno without supporting mods. now seriously don't run the car like that or you will need a new engine in no time!. take it to a specialist to get it sorted.

tooquicktostop Posted May 9, 2010 Share Posted May 9, 2010 I would say that has had items removed before coming to the UK as mentioned, no way it would have run a T51 for any long period of time at 1bar and lasted this long Quote Link to comment Share on other sites More sharing options...
MartinBattye Posted May 10, 2010 Share Posted May 10, 2010 was your dyno a straight power run?? or was diagnostic equipment attached? many on here like to scaremonger the new owner with tiny tales about how you can and cant do things.. the hadware is nice.. but the setup is not ideal... fact is it wont go pop the instant you put you foot down. get the motor checked for AFR and knock at critical points... if all is well then upgrade as and when you feel necessary... if all is not well then certainly think about upgrading parts to suit the level of tune your at.

What a 2JZ with a T51 on stock 440cc injectors and stock ECU at 1bar is safe? It's not scaremongering, it's advice that will stop the engine from going pop.

skyludeboy Posted May 10, 2010 Author Share Posted May 10, 2010 forgot to add the ecu has a sticker saying 'farina racers' what ever that is, might be the guys that built it in japan, sticker says something in the lines of 'we are madmen and pass this cancer on to you' lol will take a picture Quote Link to comment Share on other sites More sharing options...

Worst advice ever....fact is there are idiots like this that tell you it's completely fine to run a t51 with no supporting mods whatsoever....ignore them and get it to a specialist as soon as you can Quote Link to comment Share on other sites More sharing options...

Scaremongering !, that is very dissapointing as I am far from trying to ruin this guys day with bad news but the truth of it is he does not really understand the complexities of a single build and the supporting mods required, it would be very wrong IMO to advise the chap to add mods when necessary and not to get a fuel management system NOW The spec is unknown but needs to be checked, I hope I am wrong and it looks OK but I fear the damage may have already started on the engine I have lost an engine on a dyno due to poor set up and mapping so I do have a little experience and know that I good advise is vital at the start of your single ownership Quote Link to comment Share on other sites More sharing options...
MartinBattye Posted May 10, 2010 Share Posted May 10, 2010 you could have the worlds worst setup with piggy backs etc and still have ideal fuelling.. losing an engine on a dyno is crazy.. it must have been a long way out.. and the dyno operator must have had little engine sympathy Quote Link to comment Share on other sites More sharing options...
dandan Posted May 10, 2010 Share Posted May 10, 2010 Perhaps the fuel pressure regulator was adjusted to keep things safe on boost and part throttle and off boost rich running like a bit of a dog elsewhere. Quote Link to comment Share on other sites More sharing options...
michael Posted May 10, 2010 Share Posted May 10, 2010 I know of an MR2 that came over to the UK with a Farina Racing ECU - it was always a bit of an unknown but it put out much healthier dyno numbers that cars with similar mods and a standard ECU. Probably best to get more diagnositics done as has already been recommended, if not to just protect the engine then to optimise what you have and make the most of the turbo with a few extra mods.
