Just out of curiosity has anyone used one of these ?

On their site they mention a version that has an adapter loom to plug into an R33 GTS25T - but uses map sensing .

From what I hear one of their selling points is that it runs constantly in learning mode so is supposed to be able to adapt to changing circumstances .

Anyone ?

Wasted spark is usually fine. Lets do the math for it, I enjoy maths anyway (wtf)? At 8000rpm you have 15ms per 2 rotations (4 stroke) so you have 7.5ms to charge, discharge and rest a wasted spark s

a very good friend of mine is running an adaptronic on his beams 3sge, and it seems to do the job quite well, we hook the laptop up to it regularly, im not sure on the model but it has all the tuning capabilities of the big brand computers, and a lot cheaper than them also, and there Australian company as well ?? , but he is more than happy with it, and another mate is looking into getting the plug and play option for his 25det also

I run the adaptronic on my rb20det made 320hp on 18psi with a 2876r on the side of it.

Appears very easy to use, has Self tuning and closed loop only downside which really isn't to much of a downside is it only has 4 injector outputs, But this will be changed in the new model comming out next year. I picked mine up new for $990

Heres a couple of screenshots from my tune.

I run one,

Ran my RB25DET and now is running my RB25/30DET.

Absolutely no issues with it.

If you look on the field apps page at the white R33 that's on there. That's my one.

It can be ran in one of 4 modes.

Open Loop, uses no O2 feedback

Closed Loop, Uses O2 feedback and trims the maps by a percentage, this percentage is erased each time the engine is started.

Slow converge, uses O2 feedback to SLOWLY modify the fuel values in the fuel map. This takes a long time, and is good to run in to get the maps just perfect at cruise.

Fast Learn, uses O2 feedback and very quickly makes changes to the map. Running in this mode is for tuning only really, whack it in this mode with a wideband, when the fuel map is a fair way out, or you've just made some changes to the setup and need to retune.

ECU also has features such as Launch Control, Traction Control, a few boost cuts, air temp correction, water temp correction, Soft rev limits, and hard rev limits, log direct onto a laptop, also has the video controller that plugs into a 7" tv screen as an extra unit.

The Map sensor, is also tapped into the wires that run to your AFM, so you unplug your AFM, T into these wires, and wire the map sensor in (3 wires that you have to solder and tape in) and then connect the Map sensor in physically. The loom is a simple plug and play. Go nuts setup. Works perfectly.

Any questions, PM me.

They are a very capable unit, however i have issues with andy selling plug and play units without an Air temp sensor, which is absolutely essential for a map sensored ECU.

Why do you say this?

with out air temp you can not know air density, there for pressure alone is useless...

The change in density would be minimal though, to the point, that cars tuned on the road, generally have a safe tune in them, that the minor amount that they can lean out from this heat up, is negated from the slightly extra fuel anyway.

That and the fact the car can run in closed loop, so it can richen or lean out the mixtures accordingly

Every map sensor equipped ecu i have seen, power fc, autronic, motec, haltech all use the air temp sensor, so i assume it is needed.

That adaptronic, can use it, if you buy one. The only difference I'd be able to see, is if the PowerFC, Autronic, Motec, Haltech etc, COME with the air temp sensor, which, from my limited reading on these ECUs, they don't come with one either... They may, please correct me if they do.

So I don't see the issue here. If you want one, run it. I haven't had an issue with mine, without running one, but I keep my tune conservative, not on the edge.

To tune the air temp correction properly, you need to run the car on the dyno in different heats, and then adjust the temp correction, but, at the same time, humidity will also affect the tune, so how many of us are running ECUs that can alter for it?

2 points: Autronic does not have an air temp fuel correction map, this is for a very good reason, its a mathematical formulae, whereby the change in temp effects density.

The change is far more than you would believe. I have tuned 2 cars with adaptronics without Air temp sensors. The frist one was a brumby with no intercooler, left with a 12:1 tune at WOT. Customer fitted a water/air intercooler, running exactly the same boost, came back running 14:1 WOT. The other car was tuned conservatively in winter, and when it got hot in summer would blow black smoke. So i could either retune it every 6 months, or lean it out, then in winter it would run lean.

I understand that the sensors are available, and there is a table in there, but for the added expense to adaptronic to make the product correctly, i wouldnt risk it, i mean all the ecu's should come with it, and the table should be set and locked. I mean put it this way, if you are a customer, and have a P&P ecu fitted, then down the track the motor blows due to the ecu who do you blame?

I have the formula somewhere for the change in density VS air temp, and it is quite substantial, there is also the effect of humidity, but i think the design of an air temp sensor must incorporate this also.

Its easy enough to wire up the Air temp Sensor, For the price of the ECU and what it does it does allow some leaway for you to give it the benifit of not coming with the temp sensor.

Still if you add the cost of a temp sensor to the ecu and plug in harness your still under $1400 for a ecu that does alot of the same functions as alot higher priced ECU's on the market today.

I am going to be installing a temp sensor with my adaptronic jsut to be safe on my new engine but it ran my old rb20 with 300hp atw with no problems for 12 months and didn't see any large amounts of black smoke

For that reason I don;t know why people don't recommend them more oftern.

few reasons, but they are a very simple budget ECU that gives competant results (tuned them on 4age's and turbo hondas)

i would seriously wait for a full 6 channel IGN and INJ model before fitting it to any of my customers cars.. till then it will remain the 4cyl base ecu.

What do you mean by 4 cyl ecu??

I've got one running my 26/30 n/a setup and it seems to be coping well with the 140 rwkw it's made.

The only thing I can say wrong about it, that when trying to turn my car over sometimes the CAS and the ECU have a conflict and sort of cut the ignition out, only does it every now and again.

Yes I have the impression that its mainly aimed at 4 cylinder engines with its four injector and four coil drivers in the box .

The air temperature and therefore density issue is a biggie and without some means of knowing what the temperature of the air is I'd say it's impossible to tune for a wide variation in atmospheric conditions .

The Autronic I used to have (SMC) had I think options for an air temp correction map or what they called a charge temp estimation table which works much better .

The thing I never forgot was that some switched on tuners used to put a MAF sensor in front of map sensed engines while they tuned them , message in there somewhere .

      What brakes on R34 GTT(Europe)

      Sorry, just assumed that talk of coloured pads meant EBC red/green/yellow/shit stuff. I don't know the DBA pads, but it's a reasonable bet that they will be OK. DBA make good stuff generally. Those 4000 series rotors I linked to are very good. I may well replace the RDA rotors I have with those when required.

      The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.

      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.
