One question to all the Mines haters.

Have you actually had one in your car and has it caused issues?

I understand the theory behind what you are saying, but as soon as you modify the exhaust/boost/cooler/intake then the standard ECU is not longer tuned for your car either.

I've not used a Mines so am not speaking from personal experience but I've seen a ton of people on here poo-pooing them with what seems to be no actual evidence to support the criticism however many people who have run them or do run them are generally always speaking out in support of chipped ECUs like a Mines.

So may I ask those who are so critical of chipped ECUs to actually support their theory with some evidence?

Again, I'm not pro or against them as I've never used one, but it seems people who have on here have had generally good experiences.

The only mods he has done is an exhaust and upped the boost. The first issue to me is the boost spiking, this to me identifies something else is wrong.

If he drops the boost I cant see why the standard ecu cant cope or even the mines for that matter. Its not like he has considerable modifications. I agree that a tune would help a lot but it doesnt appear to be the issue yet.

I was running 12psi, had an intercooler and exhaust and that was enough to get complete boost cut where the ecu kills the ignition for 2 seconds, I also got the horribly misfiring and complete lack of power over 5.5k due to it running so rich it was misfiring (below 10:1 when it got on the dyno.

The stock ecu can shit itself as soon as you start flowing much more air than standard.

I am not a Mines "hater". If you live in Japan and can take your car to Mines and get them to make a chip for your car that would be fine. But buying one off ebay and sticking it in your car is like a lottery. For some people it works better than their stock ecu but for others it may either be worse or else it may be bettr but not optimal. I have had a chipped R32 ecu running my RB25DET (245awkw) but my car was tuned on a dyno and the chip tailor made for my application. People like Toshi make mail order chips for people who list their mods and these will work better than the stock ecu and he has many happy customers, but I would never buy one because i want my tune to be spot on.

Re my post above, yes I had a mines chip in my ec, it was absolute garbage, they had to wind the cas back as it had advanced the ignition so far it would ping on 98 octane fuel with octane additive as well.

Seen many work very well first hand. Never heard of one actually running bad, they are based on a stock car with no more than breathing mods. I personally believe limitations/expectations can be taken as the same as stock, with dyno time to support.

Have although read LOTS of non-user feedback :banana:

EXACTLY, i used two, not a problem at all. Car runs better but try telling that to non-users. Good luck. i made 210kw+ on both and no my engine didnt "BLOWWW UP"

Mine had the CAS wound all the way back to stop it pinging and ran so rich the wideband sensor was maxed out, I was even getting rich misfires so must have been around 9:1 AFRs.

So there is one example.

Thats your experience. I used PFC, stock ecu, 2x Mines ECU and about to try NISTUNE.

MINES ECU was excellent, nothing bad about my personal experience with using mines ecu. ran 13.3 with shit tires, car went nice n hard, thrashed it. never missed a beat, even in 38c degree heat when i took it to heathcote.

Running an off the shelf remap is always going to be dicey, just because it works some times does not mean it is a good idea.

Everything is dicey. Tuning, modding up the car. You waking up and getting out of bed if "dicey". IT WORKED IN MY case is what im trying to say, just as well as PFC.

Or I could just pay the $300 to get it tuned and not worry about it :ph34r:

300?

First tune was 950.

My second was 1550 including some other work..

And now my 3rd is 900-1000.

point is?-its never 300, not in my case anyway.

But anyway, we could go all day. i get what your saying, it is less riskier, if you tune your car. What some people dont get is MINES ecu can work, but dont want to even hear about it. In any case, me no care, ill butt out.

As said previously, this guys setup is hardly highly modified it really only has an exhaust and some more boost. Once he drops the boost I don't see why the stock ecu or a mines ecu can't do a reasonable job.

has this seriously been going for 4 pages...

just turn down the boost... youve basically got a standard gtst there.

want more power spend more money, its pretty straight forward I would of thought...

If you read the title of the thread you will see that the focus of the OP is to go faster. To do that he will need a tunable ecu. If he goes to EFI they will sort out his other problems. His own understanding of how things work appears to be limited.

If you read the actual thread he has a lot more basic problems to fix before he worries about modifications for more power.

You are spot on, you cant just turn up the boost and expect power, you need to modify the car, exhaust, cooler, maybe fresh coil pack before even considering turning up the boost BUT, i can assure you that OP problem is not ECU as i used this ecu previously. Its something else, the problem was there even before Mines ecu, and my suggestion is to get good flowing exhaust, good cooler, coil pack and turbo tech manual boost T. And than run 12psi. Thats how i made 208 kw, and you should too providing rest of your car is in good nic. :D

why on earth did the PFC not work? in 12 years of playing with them not once has there been an issue like yours...... in fact the PFC ignores allot of minor issues the NISTUNE wont, chances are the nistune will be worse than the PFC in your case. The PFC only cares for AFM voltage, tps and CAS the rest it ignores..... the NIstune requires just about every sensor to be in check or it will throw a code and depending on the model may not have a DTC check box to keep it ignored.

If the PFC wont run either the tuner CBF'd or they didnt tune it..... there is an underlying issue with your car that wont be sorted with any management, which can often be a biatch to find. Any good workshop should have no issues though.

If it was me id have the PFC back in it in a heartbeat.... and find the issue.

      Unpeeling the Orange

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.

      No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).

      I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
