Alex Posted March 25, 2008 Share Posted March 25, 2008 Oh my... I got this problem whit boost on turbo #1, only 0.4 bar and whit turbo #2 kicks in i get 0.9bar.... That's not a problem - that's how it SHOULD work! Turbo 1 at low rev = 0.4-5bar. Both turbo's at higher revs = 0.8-0.9bar. Link to comment Share on other sites More sharing options...
JustGav Posted March 25, 2008 Share Posted March 25, 2008 Hmmm...just had a thought, and I hope I'm wrong... But if the wastegate is held closed electronically, does that mean it will provide a sort of turbo boost as they just run away....and the other wire just ensures both are online....

I was thinking along the same lines, doesnt sound good though does it. Link to comment Share on other sites More sharing options...

JustGav Posted March 25, 2008 Share Posted March 25, 2008 Hmmm, wonder if one of the envy boys would be willing to pop past and enquire how the modification works (if they are still trading?) Link to comment Share on other sites More sharing options...

Tricky-Ricky Posted March 28, 2008 Share Posted March 28, 2008 I suspect its just another way of tackling the electronic version of the TTC mod as suggested earlier. Link to comment Share on other sites More sharing options...
JustGav Posted March 28, 2008 Share Posted March 28, 2008 I won't call this a reprogramed ecu.. 41A red 42B Yellow 45B brown Does those 41A,42B,45B refer to the pins that it connects to, because it seems really odd 41A = Doesn't exist (Can you confirm pin location) 42B = Sub throttle position sensor 45B = Intake air tempreature Any markings on the little chip on the daughter board (I'd be interested to know which IC it is), from what I can see, it has a variable resistor, a fixed one, a diode and what I'd hazard a guess is a voltage regulator. Although I'd assume the red wire is a power wire, but should really confirm. Link to comment Share on other sites More sharing options...

Oh dear... that was my first though as soon as I saw air intake connection..... Might be a slightly advanced one that allows them to adjust it... Sorry flyby, I'll stop looking into these things because it always seems to be some very odd with your ECU Link to comment Share on other sites More sharing options...
flyby Posted March 28, 2008 Author Share Posted March 28, 2008 I just talt to turbosystems on phone whit my bad english. He says he has not seen a supra since 1995 in his shop. The little eletronic bord is some kind of Frequency Controller. The smalle botton under my dask, work as a boost controller, and wourld make the turboes run ass fast as possible Link to comment Share on other sites More sharing options...

The boost controller thing?? looks like Wez and I may have been correct in our assumption in that it just electronically holds the wastegate shut (which isn't good)....

flyby Posted March 28, 2008 Author Share Posted March 28, 2008 I thing yout worst fear is right. I can recall he said that the turbo can only make 30psi, but i thing it was my bad english understanding, and he proberly said 13psi and that is 0.9 bar Worud it be the best if I try to remove the eletronic in the ECU, and reconect the 2 wires, ande if anything is back to normal. If my turbos is not dead.... Or do I have a boost leak some where so both turboes can make more than 0.9 bar of boost? Link to comment Share on other sites More sharing options...

My gut call would be to remove the 'interesting' modifications BUT here is the gotcha... Do you know what else has been changed? It is a risk to consider....

Not as simple as that, its been discussed a few times before, do a search. I wouldnt bother looking at this route. Link to comment Share on other sites More sharing options...
Sharpie Posted March 28, 2008 Share Posted March 28, 2008 what is the price on a UK TT ECU auto ? I noticed that ibrar has a second hand unit on his new website for ~£80 but, that too has a "modded sticker" on it from SuperChips. Looking at their site, it says a 55BHP increase for £499 fitted and inc. VAT http://www.superchips.co.uk/curves/supratt.pdf Anyway, back on track for Ibrar's site: http://www.suprabits.com/userimages/procart2.htm Link to comment Share on other sites More sharing options...

flyby Posted March 29, 2008 Author Share Posted March 29, 2008 Did you just disconnect it or join the original wires back up? I cut the 4 wire inside the ECU and and join the 2 wire outside. When I conneded the 4 wire and still left the 2 wires joins it stated again. I need another ECU Link to comment Share on other sites More sharing options...

Have you got pics showing how the 4 wires inside the ECU are connected, have they broken any tracks on the main circuit board. It looks like they might be sending a modified voltage to the intake temp sensor input, by tricking the ECU you could cause it to run richer or leaner.
