if you do a search you will find a shit load of threads all stating that :

no after market full replacement ecu works properly with the auto , although some claim they do , they dont

this limits you to interceptor type devices like the safc II or emanage

with an auto You might have to run a Piggy back computer

or you can run a

Hydra EMS computer

which adaps the auto box funcitions into it

Wat is the damage and have you seen them work on an auto

Lol dood i dont think people have had a good read at this topic. Mate unfortunatley you cannot use a apexi power FC because it doesnt support automatic gearbox intergration. You could try wolf3d im stuck in this situo as well. Too head you in the right track you will have to have a piggy back ecu or Use another ecu for Fuel and Ignition and use the standard ecu to run everything else. Also try a nistune supplier http://www.nistune.com/workshops.html

mythbusters ahoy

and blast from the past - beyond 2000

you cannot (well shouldn't) use most stand alone ECU's on ECR33 Auto

this is because the standard ECU has all the logic for gearchange control

if you replace this ECU with a standalone that is a MANUAL ECU (that is, does NOT support the ECR33 AUTO box) then it assumes manual

it wont back out timing on gear change, which results in harsh/jerky gearchanges and the changes put stress on the box

this "gotcha" applies to most stand alone ECU's, be it Apexi, HKS, Motec, Autronic, Wolf etc etc etc

your best option is nistune or emanage or remap or safc

all of these options keep the stock ecu, and retain the factory gearbox logic

users have insisted that powerfc (and other stand alone ecu's) etc work on AUTO

and the truth it, it does work, you can start the car

you can drive, you can boost it etc

but the changes will be harsh and youll risk the box

if you are OK with that, go for it, but you know the risks/results

this "gotcha" only applies to ECR33 auto where the gearbox is electronic control logic and needs the main ecu to do the logic change for it

cars such as vl turbo, toyota either have seperate ECU control for autobox or mechnical (vl turbo)

      RB25DET with solid lifters - which cams ?

      By TurboTapin · Posted

      Yea that's a fair assumption. I'm presuming they call them solid lifters as they have no moving parts like hydro lifters.

      Why am I hitting a power wall with my stroked RB25?

      I believe you're confusing WMI with water injection. Looking at that graph, the 93aki+WMI car is making more power than C16 race gas. Boost juice, which is what I also run, is Snow Performances 50/50 premix.

      GCG is a good company, they're a major distributor for Garrett in Japan as well.

      Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣

      I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date? Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it. Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that. My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).
