Jellybean Posted November 5, 2012 Share Posted November 5, 2012 Hey Running , SARD Analyse ROM on Stock ECU I had the Supra AFR's checked out last year , everything was spot on. 95 Octane is only available here so would it be recommended to get her remapped ? Was talking to one of the garages over here , they dont remap cars but he said any of the 2jzgte cars he got; after a remap she ran alot smoother. What would tuners recommend? Ideally I would like a syvecs but you would really need to have the car mapped using the local fuel available here Quote Link to comment Share on other sites More sharing options...

Jellybean Posted November 5, 2012 Author Share Posted November 5, 2012 uk spec ecu ? Jspec , sorry didnt think Jspec and UK cars had different ECU's on a 2jzgte Quote Link to comment Share on other sites More sharing options...
Jellybean Posted November 5, 2012 Author Share Posted November 5, 2012 Emailed one of the Tuners here in Ireland, outlined the spec of the car which is fairly basic and his recommendations on what ECU to use with the stiplualtion I want the ECU to control the boost. Outline the Price and primarily I was looking for advice on best application for my needs. Response I recieived was "How much do you want to spend" About sums it up over here, was hoping for a bit more insight. Ah well, looks like RyanG will have another customer!

tony tt Posted November 5, 2012 Share Posted November 5, 2012 What level of tune are you going for on 95ron? Quote Link to comment Share on other sites More sharing options...
Jellybean Posted November 5, 2012 Author Share Posted November 5, 2012 What level of tune are you going for on 95ron? BPU, maybe in Parallel versus Sequential like Malcoms Quote Link to comment Share on other sites More sharing options...
Dnk Posted November 5, 2012 Share Posted November 5, 2012 Jspec , sorry didnt think Jspec and UK cars had different ECU's on a 2jzgte A uk car is set up to run on 95 ron, i have no issues running mine on 95 even at 1.2 bar Quote Link to comment Share on other sites More sharing options...
tony tt Posted November 5, 2012 Share Posted November 5, 2012 My Jspec at bpu went fubar on 95ron with octane booster in Ireland blew tubby two. Wasn't mapped though so hope yours will run sweet. Quote Link to comment Share on other sites More sharing options...
Alex Posted November 5, 2012 Share Posted November 5, 2012 The ECU's built in knock detection would have adjusted for 95ron the first time you used it...fitting an aftermarket ecu doesn't strike me as VFM for your tune. Quote Link to comment Share on other sites More sharing options...

Oookay...so engine detonated yeah? and you lost some pistons as well as the turbo? Only the turbo doesn't really mind what *burnt* fuel goes through it. The j-spec ceramics can go for a number of reasons, co-incidence imo. Quote Link to comment Share on other sites More sharing options...

Jellybean Posted November 5, 2012 Author Share Posted November 5, 2012 I was down getting a Geo setup on the car, Wez (WKD Imports) is very familar with the 2jz from running a pro team in the UK and Irish Drifting plus he has had numerous Toyota variants running the 2jz He just asked me if it was remapped and just suggested it was a good idea (he doesnt map cars) so just wanted to run it by you guys. I do remember Tony saying his engine went pop before when he was here. My car is running 95 last 5 years here on standard ECU; just taught I would ask. It most likely is not an issue in the uk as 98 octane is available Quote Link to comment Share on other sites More sharing options...
Alex Posted November 5, 2012 Share Posted November 5, 2012 It's the boost level...you can't go 1.2+bar. It's a real PITA for you but that's the sensible thing to do, keep it down sub 1 bar. A decat, which removes a heat block will allow more boost to be run before it complains but I'd still limit it to 1bar. I'd also, personally, fit a knock detector...see if it goes mental. If it does then go get your replacement ECU or dial down the boost. If it doesn't, carry on. Quote Link to comment Share on other sites More sharing options...
tony tt Posted November 5, 2012 Share Posted November 5, 2012 It's probably not related to 95ron bud my car might have had other underlying issues at the time i wasn't aware of but soon as that happenned the engine got changed and i moved back to the uk.

Jellybean Posted November 5, 2012 Author Share Posted November 5, 2012 Have all the bpu mods last 3 years , afrs are fine at 1.2 bar but will this catch knock? Quote Link to comment Share on other sites More sharing options...
Jellybean Posted November 6, 2012 Author Share Posted November 6, 2012 What about Water injection to safeguard the engine from knock and detonation ? Quote Link to comment Share on other sites More sharing options...
Wez Posted November 6, 2012 Share Posted November 6, 2012 So its a jspec with a SARD modified rom, can you get details from SARD on what has been done, maybe supply the serial number to them If it was fitted in Japan then it may well have been altered for more advance, higher rev limit, speed limit removed, higher boost etc etc, all of which was prob set up on their higher grade fuel, I personally would not be happy running on anything less than super unleaded but would try and stick with optimax at 99ron. Just for comparison sake, I have a 95ron map on my Syvecs, I still run the same amount of boost, ie 1.6bar on my single but you have to dial the timing right back which loses over 85hp and 70ft/lbs at the same boost level. - - - Updated - - - What about Water injection to safeguard the engine from knock and detonation ? A 50/50 mix of water and meth could help but it would need checking with det cans. Quote Link to comment Share on other sites More sharing options...

I am not too sure what rom it is but I have read up on the features; From what I remember reading you can have two roms; one that raises the boost cut to 1.3 and another to 1.4 Analyse is an ECU set to provide alteration of high boost & rev control at high speed driving, and provides accurate engine control in various conditions, such as partial range, street driving, and engine idling. Resetting items of Analyse: * Fuel map resetting. -- Not too sure if this is altered * Ignition map resetting. -- Not too sure if this is altered * Rev limiter resetting. -- NO, same as stock * Speed limiter cancellation. -- Yes * Boost limiter cancellation. -- Yes Quote Link to comment Share on other sites More sharing options...
Wez Posted November 6, 2012 Share Posted November 6, 2012 Email them, see what info they can provide. Failing that I would get it checked on a dyno with det cans. As Alex has already mentioned the stock ECUs det control is pretty damn good but if it was my car I would still get it check out, I would also want to know exactly what that rom is doing, if I couldnt find out I would be ditching it for a stock jspec ECU, at least you know what your dealing with then.

Cool thanks ,I have a chart here but she had a boost leak so not too sure how useful it is Quote Link to comment Share on other sites More sharing options...
Wez Posted November 6, 2012 Share Posted November 6, 2012 That just shows you power and torque. The reason I say stick it on a dyno is that you can go through the rev range with det cans on, checking different loads in different gears etc, you would also be able to monitor your AFR, plus its a lot safer than trying to accomplish the same thing on public roads Quote Link to comment Share on other sites More sharing options...
