Mk4Gaz Posted August 20, 2013 Share Posted August 20, 2013 Hi guys, i'm just about ready to crank the boost up, but would anyone be able to tell me definitively if I need anything else before I do ? Current setup: Stock twin turbos - j spec ceramic afaik NGK BKR7IEX or whatever the code is 1st and 2nd decats with 2" restrictor ring 3" cat back system Boost controller en route Induction kit FMIC soon to fit - but not necessary, just for bling ! Mines ECU Now i've read that the mines ecu removes fuel cut, and boost cut (not sure if they're the same phenomenon ?), but could anyone confirm this for sure, so I don't start going into silly mode every time I put my foot down ! I'm planning to run 1.1 bar max, I know that any increase over stock is likely to stress any engine, but don't want to risk pushing the old girl too far ! Can anyone see anything blindingly obvious that I may have missed ? Quote Link to comment Share on other sites More sharing options...
tony tt Posted August 20, 2013 Share Posted August 20, 2013 I've a mines bud and its right enough no need for a fcd with that. Do you have a decent boost gauge to keep an eye on it? Quote Link to comment Share on other sites More sharing options...
Mk4Gaz Posted August 20, 2013 Author Share Posted August 20, 2013 Thanks Tony, I was hoping you'd come along, as I remember you mentioning you also had one I've got a pro sport stepper motor boost gauge mate, and I'm pretty sure its accurate. Was always spot on with my gizzmo msibc in my mr2 Quote Link to comment Share on other sites More sharing options...
tony tt Posted August 20, 2013 Share Posted August 20, 2013 Nice one mate. You won't believe the difference bpu makes bud. You are in for a lot of fun Go for 1.2 mate the old girl is well up for it I'm sure Quote Link to comment Share on other sites More sharing options...
tony tt Posted August 20, 2013 Share Posted August 20, 2013 Just had a look again at the list bud do you have a walbero or Bosch upgrade fuel pump? Quote Link to comment Share on other sites More sharing options...
Mk4Gaz Posted August 20, 2013 Author Share Posted August 20, 2013 Sorry, forgot that bit - and I only fitted it on Sunday! Yes, a walboro 255 lph pump too Daft question, but does it make THAT much difference over stock, I mean its really noticeable? Quote Link to comment Share on other sites More sharing options...
Scott Posted August 20, 2013 Share Posted August 20, 2013 Are you not seeing 1.1Bar just now? I always hit 1.1bar on my mines ECU. Quote Link to comment Share on other sites More sharing options...
Mk4Gaz Posted August 20, 2013 Author Share Posted August 20, 2013 Scott, I've not driven it since fitting the pump and 1st decat on Sunday! Previous to that, it was about 0.8 bar on full boost, so interested to see what it makes without a boost controller. Just wanted to confirm that I don't need a fcd before I go out stamping on the loud pedal Quote Link to comment Share on other sites More sharing options...

The Mines ECU generally increases the boost to 1.1bar with zero other mods done (no decat, nothing). Have you physically checked that it has a Mines ECU? Different ones have different settings/features/options so it's probably a good idea to get the serial number and send it off to Mines to see what it has done to it.

TT Paul Posted August 20, 2013 Share Posted August 20, 2013 boost controller fitted ?? Quote Link to comment Share on other sites More sharing options...
Mk4Gaz Posted August 20, 2013 Author Share Posted August 20, 2013 Paul, the boost controller isn't fitted yet mate, I'm hoping its going to turn up tomorrow........... Scott, I haven't dome much looking into it to be honest, just that when I was running the power cable for my amps, I found the ecu has a mines sticker on it - the proper foil gold one, so I believe it to be genuine, had one on my mr2 years ago, so kind of know what they do - ish. Previous to the weekend, my car had the cat back and 2nd decat fitted, and was making circa 11psi on wot with both turbos running, over 4k rpms. The guy I bought it off, said it had been dynoed at 362 bhp at that level, but I have no print out to prove it, and I don't even think he was aware of the ecu, as he didn't mention it!

Scott Posted August 20, 2013 Share Posted August 20, 2013 There's probably versions without the boost increase. If you email mines with the serial number they'll get back to you and tell you what has been done. Mine had the following: Fuel Cut Removal Speed Limit Removal More aggressive fueling/timing Boost pressure raised to 1.1bar Rev Limit Raised to 8k RPM I think that was all but there may have been more.

tony tt Posted August 20, 2013 Share Posted August 20, 2013 My rev limit isn't increased with mine. I think ill send them an email. Quote Link to comment Share on other sites More sharing options...
Mk4Gaz Posted August 20, 2013 Author Share Posted August 20, 2013 I'm definitely going to do that, I think the rev limit may be manuals only, possibly as the auto box doesn't like revving that high - or I could be speculating rubbish! I've read that the rest is pretty much right, raised boost maps, fuelling/timing maps for bolt on mods, fuel cut removed, speed limiter removed Quote Link to comment Share on other sites More sharing options...

I've read that the rest is pretty much right, raised boost maps, fuelling/timing maps for bolt on mods, fuel cut removed, speed limiter removed The rev limit can be changed on the auto too, it's not by as much of a margin though. I'm guessing it's a bit of a rare option to have the autos with the increased rev limit though..... to save the box I would guess? Quote Link to comment Share on other sites More sharing options...
Mk4Gaz Posted August 20, 2013 Author Share Posted August 20, 2013 That's my thoughts too Quote Link to comment Share on other sites More sharing options...
tony tt Posted August 21, 2013 Share Posted August 21, 2013 I've emailed mines about my ecu so ill post up what they come back with and how long it took for a reply. Quote Link to comment Share on other sites More sharing options...
tony tt Posted August 25, 2013 Share Posted August 25, 2013 Got an email back today from mines wanting a pic of the unit so I've sent it to them even though I provided all the serial numbers. Hopefully they won't be long with a response. Quote Link to comment Share on other sites More sharing options...
SPG Posted August 25, 2013 Share Posted August 25, 2013 My last Mines ECU rev'd to 8,000rpm, only found this out when I got cramp whilst sitting idle. Quote Link to comment Share on other sites More sharing options...
tony tt Posted August 25, 2013 Share Posted August 25, 2013 I think it only increases the rev limit on the Manual version. Quote Link to comment Share on other sites More sharing options...
tony tt Posted September 6, 2013 Share Posted September 6, 2013 Response from Mines. When this VX-ROM left our shop it was for a (CHUKI) middle version, automatic transmission SUPRA JZA80 Fuel mapping and ignition timing optimized Speed limiter cut Rev limit +500 rpm Can handle up o 0.9-1.0kg/cm2 boost MAX for use with 100 ron octane rated fuel. I have to say I haven't noticed the raised rev limit although throttle response has been improved. Quote Link to comment Share on other sites More sharing options...
