patrik Posted September 9, 2008 Share Posted September 9, 2008 Hello guys, ive now installed the mines ecu i bought from jacko. the first thing i noticed is that the sound is much harder :-) we installed on a friends supra to and he noticed the same it was really a big difference when reving the engine at stand still. he is more insane than me so he was chosen to try it out. its pouring cats and dogs here today so i let him have the fun. according to him he can feel a bit of power gain. soo the question is does the mines ecu really raise the boost? ( i have no boost meter so hard to tell). it feels like it goes faster but not that much really but it removes the speed limit thats for sure. and the auto changes as usuall so i suspect i have to shit with the manual to see real change on the rev limiter.

TrickTT Posted September 10, 2008 Share Posted September 10, 2008 ECU cant change the boost, you need a boost controller or different wastegate actuator spring for that, but the Mines ecu does change the fuel map so it should make a bit more power, and maps it to higher levels of boost than the stock ecu. Low rpm gearchanges are much the same as stock, but high rpm, full throttle ones are much quicker. Quote Link to comment Share on other sites More sharing options...
Nick Posted September 10, 2008 Share Posted September 10, 2008 Depends on how they've mapped it, as they're not all the same. Usually it's an adjustment to the fuel map, increased rev limit, speed limiter removal and sometimes increased boost. Note the VX-ROM won't increase the boost level, it may/may not be mapped for higher boost. If you send them the ECU serial numbers and the Mine's serial number together with the vehicle make, model and year they can give you some basic details. There's a form on their website. http://www.mines-wave.com Don't expect a quite reply. Nagahama-san is the only person that deals with these inquiries and he's in Dubai at the moment.

Guest sunnyG83 Posted September 10, 2008 Share Posted September 10, 2008 Well with both cats still on and running this ecu i could see the boost hitting 1bar constantly on WOT Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted September 10, 2008 Share Posted September 10, 2008 The one I had a fiddle with pulled fuel and added timing, the advanced timing making it sound a bit harsher. Be aware that the added timing means it will be less tolerant of poor fuel. Quote Link to comment Share on other sites More sharing options...
patrik Posted September 10, 2008 Author Share Posted September 10, 2008 i guess i will have to buy some sort of boost controller to see if it increased the boost. it feels quicker but not by much. i have actuallly tried the mines site but i posted my question there 2 months ago and still no reply :-) so slow it is. i think the ecu should be mapped to 1,1 1,2bar or something and since there is already a walbro pump in so should be no trouble if it was. i use the 98 ron fuel here i could go with the v power but its not worth the cash i think.

Wez Posted September 10, 2008 Share Posted September 10, 2008 ECU cant change the boost, you need a boost controller or different wastegate actuator spring for that, The ECU regulates the boost using the wastegate VSV, if they went to the trouble of altering the fuel and ignition I dont see why they may not have adjusted the boost as well. All a boost controller does is take away the control from the ECU. It certainly wouldnt be mapped to over 1.2bar since the stock map sensor limit is just above this.

Scott Posted September 10, 2008 Share Posted September 10, 2008 I have one. The boost is raised to between 1 and 1.1 bar. I think its set for 1 bar but varying cold weather up here let me see 1.1 bar sometimes. As Chris says the timing is altered, i think it can run a little lean up top. Never put anything other than 99 octane into the car. Be very careful though if you still have both cats in as the temps will soar. Oh, your rev limit is now 8k Quote Link to comment Share on other sites More sharing options...
TrickTT Posted September 10, 2008 Share Posted September 10, 2008 Oh, your rev limit is now 8k The rev limit on mine is 7k. Only way to find out for sure what spec you have is to take the cover off the ecu and send some pics of the mines ecu board to them. They replied to me the same day.

Ahh yes, i'm forgetting they are all different. My rev limit is 8k lol. Quote Link to comment Share on other sites More sharing options...
patrik Posted September 10, 2008 Author Share Posted September 10, 2008 ok i will give mines a new try and give them the serial number so they can check it out. thanks for all the replys. (i also thougt that the ecu could have a rasied boost function how else could the oem ecu control the boost?) Quote Link to comment Share on other sites More sharing options...

Homer Posted September 10, 2008 Share Posted September 10, 2008 It does raise the boost. Read my first post. Was it decatted too? I'd wager the decat raised the boost, not the ECU. I have driven a fresh import with a mines ECU and both cats in and the boost was stock (just under 0.8bar) Quote Link to comment Share on other sites More sharing options...

Nick Posted September 10, 2008 Share Posted September 10, 2008 The mapping is quite conservative, but it will be done on 100RON fuel. I'd say if it does have a boost increase it would be 1.1bar max, probably 1bar. Many of the maps they've done don't have a boost increase, just an adjustment to the fueling&ignition and a small rev limit increase. Keep the inquiry to the point with all the necessary info. If you ask a lot of questions they'll just ignore you as they get a lot of inquiries and they don't have the time. Even when you live 30 minutes away it can take days to get an answer at times !!!
