Hey,

As the title suggests, I'm after some help with upgrading my computer.

I've got a 20det with the basic to mild mods and I want to know why and what you would recommend.

Basically I'm tossing up between the Apexi power fc and a microtech. As far as I understand, there both pretty well much the same (except for the afm), Leaning more towards the Apexi??

Your response would be great, as Im looking to do this next week.

Many thanks in advance :)

no need for either, remap the standard one.

cheap and easy and good gains to had.

plus youll retain the factory operation and loom.

if your in melbourne speak to dr drift.

a powerfc will set you back 1400 for the rb20 as its an ap engineering model

have a chat to him, this man could remap a lawn mower and get it to make more power. no need for powerfc unless you really really want one and its hand controller, he could get the same power + tune state out of the stock rb20 ecu.

remap = $300

if u want it dyno tuned = $350

and if something is wrong another $300+

so you pay almost $700 for a ecu remap that you cant sell for $50

or a pfc for $1200ish

and u can selling it for $900

and all the other facts... pfc does much more, will give you more power, more ppl tune it, etc etc

what happens if ur tuner who has remapped the ecu closes business.. or is busy, or not in town/???

trust me! AP PFC

i wasted over $700 on ecu remapping and dyno time and the car was running like shit!!

and the tuner is suppose to be the best in the business

i cut my loses, got a real ECU

i concour with silver gts-t sounds like very simular experience

bad experiences with remaps

not much power gain for the money spent

locked into the one tunner

Remap i gain 5-10rwkw all up with all the dramas approx $1.1k

i gained 33rwkw with the wolf3d cost $2000 all up fully tunned drive away

now 20rwkw+ for $900 is a good gain to me

Edited by EVL032

There are good and bad points about both...

I have had 2 cars remapped.

Case no 1. RB20DET cefiro with usual mods. gained 26rwkw throughout most of the useable power range. Remap cost me $250 + $120 for the dyno time... so $370 all up....

Case no 2. Auto car with bigger turbo (no power fc made for the car) did'nt want to spend $2000 for an ECU. Gained approx 20rwkw, removed speed cut, removed TP limit, better fuel economy... Cost. $100 for an eprom burner, $25 for a UV eraser...

I did all the tuning myself and have learned a lot in the process...

I can offer the following advice. If you are going to get a rempa get EVERYTHING you want to mode done BEFORE the remap. and if you have a good tuner and don't plan on modding the car further it is an excellent option.

If you are going to continue to mod the car and want a flexible system get the power FC... But be prepared to pay $1700 before have it back on the road...

With a good EPROM tuner you will get excellent power from the standard ECU. There is neumorous GTR'S running 1000rwhp running the standard remapped ECU in japan. they have been doing it there for 15 years and have it down to a fine art.

Hope this helps :D

Agreed CEF11E...

I had mine done by Dr Drift and gained close to 30 rwkw.

If you get it done get it done by some1 who knows what theyre doin.

You can get very close to the gains of a Power FC yet you cant get the flexiility..... Your choice at the end of the day.

I emailed dr-drift regarding a few things and one was a remap.

he asked what mods i'd have when the ecu is to be done.

i told him and he said he has a few generic chips for certain mods.

my one was for rb20 engine, rb25 turbo, 14psi, FMIC, exhaust, filter, fuel pump.

stock injectors, fuel pressure and afm.

he said can be done for about $400 (he will send me the ECU) and when he is up in Brisbane next, he will meet up and fine tune it for me if required.

Now that is all I want out of this car in terms of power so that is a good deal.

I will probably change the car before I go any further with mods..

if you plan on going all out later on, then might as well get PFC or other full management system.

    • To plug the hole. The engine plant may not have known whether the car it was going into had a gauge or not. It was a long time ago and the integrations might not have been fully modern. Or they might not have cared because the extra inventory and processes to save a few cents on the sender might have cost more anyway. But please tell me you are not still confusing the idea of a pressure gauge sender, and an oil pressure light switch. The switch will be out there. In a separate hole. Probably with only one wire running to it. Running the light.
    • Blower needs to go low on the exhaust side, displacing the AC and PS, which you have to decide whether you want to keep and how and where to relocate if you do. Electric option for PS is, at least, helpful. Sadly, there is no workable 12V electric AC of any value. Whilst the blower is the last compression step before the throttle, and so it might seem a good idea to have it near the inlet manifold (as mentioned above), you probably want it to go through an intercooler first, so, having it on the opposite side of the car facilitates that air flow path. The turbo discharges into the blower, so proximity of the turbo's compressor outlet to the blower's inlet is nice. But then you might want to intercool that too, before boosting it again....which would probably be a ball ache. Routing pipes out to the front and back could be a bit shit. If there was room for (at least) a small (but preferably larger) water to air core on that side, then that would probably be the best approach. I guess a reasonable alternative would be to locate the blower where the alternator is (more or less, associated with the inlet manifold, per Matt's thought), and somehow incorporate a water to air core into the manifold, sort of like they do for modern blown V8s. The big difference here though is that those V8s have only the one throttle (upstream the blower) and only the one compression step (the blower) and no need for too much in the way of bypass/blowoff valves. Whereas in a twin charged 6, you do need to think about one or two bypass valves associated with the 2 compressors and you would prefer to have the intercooling done before the air has to pass through the throttle. You'd like the throttle to work approx the same no matter what the compression is doing. But if it is located in hot air stream before a cooler, then sometimes the air will be real hot, sometimes it will be quite cool, and the throttle mapping/response will be quite different between those two cases. The throttle, if sized for hot air, would be too large for cold conditions. It's all a ball ache.
    • Package SC on exhaust side. Remote mount turbo. Still a fair bit of room when you get creative on the inlet side of the motor too. Especially if you can get really creative with the welding, and effectively build it into the bottom of the inlet manifold. Would definitely take some design work, and some trial and error, to make sure flow works well still! Might be easier to just start with the Nissan March though... All the work is already done for you...
    • I'll sit down and get a post together 😁
    • The factory oil pressure sender is no longer in the car that's what is confusing me. In the Taarks adapter I have an aftermarket Bosch style pressure/temp sender and the factory temp sender only. Oil pressure is perfect. Where does the factory oil temp sender go to if there were never any gauges? Why was it there from the factory?
