750hp Rb26 With Remaped Stock Ecu? What More Can Give Me An Aftermarket Ecu?

[GreeceS13]

You can see my setup in my signature.

I was in mind to use stock ecu as it is full remapable.. with two z32 mafs.

I have a friend here in Greece that he can map the car with stock ecu and with launch control.

The only I need from an ecu is a launch control and civillized working of my engine with 11-11.5 afr.

Has any problem with this the stock ecu after a remap?

If all theese can give me the stock ecu is there any cause for aftermaker ecu?

I can buy also a brand new LINK Generation 3 ecu that it is very cheap and it can work with stock sensors.. only need an air temp sensor. And with a solenoid can adjust the boost pressure (so if I put the Link, I will sell my apexi avc-r).

But which will be the gainings of an aftermarket LINK ecu for me? For other people that wants more for an ecu will be usefull but for my requirements that I said you?

Your replies will be very important for my choice

Hey buddy,

The factory ECU is as programmable as the Apexi PowerFC or the LINK ECU. Link has not got such a good name over hear but there are also not many tuners that do a decent job in regards to aftermarket ECU tuning, so it may just be that they do not understand it's structure.

The factory ECU will be able to give you everything except launch control but you can buy these as an addon and they work very well. I used a factory remapped ECU in my R32 GTST and made 260rwkw from the RB20. I have sinced moved on to the RB25 (as I had one lying around in the corner or the shed) and will also be using the factory ECU for it. It will be tuned to 600rwkw plus I will be adding gas to it later. Any of the options you have mentioned above will work for you, but the Nissan computer will be the most reliable. You can use the consult interface for diagnostics and if you have someone who can do the remapping for you that is close by, then that is great also. Go with the tuner you trust and the system he or she is most familiar with.

hi,

you should go with whatever ECU option is locally supported, find out what tuners are near you and find out what they use

you would be mad to fit an ECU that on-one locally can tune for you, cos then you are stuck with an ECU that can't be tuned or fixed later

so if you have a local guy who can remap and he is reliabable then this might be your best bet, just make sure you have a dyno and a good tuner

both the G3 link and the factory ecu are good units but it comes down to the operator and application.... even ABE-san from BLITZ in japan (arguably one of the best ECU remappers in japan) found the limits of the fatory ecu in the BLITZ R34 D1GP drift car and needed to go aftermarket (MOTEC in his case)

I have tuner who can install a daughterboard in the stock ecu two have more than one maps!

And he can put in one map launch control map! Not rev limiter... launch control! Theese are what he said me!

paulr33

For LINk we haven't anyone mapper in Greece. Anyone have link ecu waiting an australian tuner to come to Greece some times in a year...!

We have good tuners for power fc but the tuner that tune nissan ecus are quite good too.

URAS

I don't know the jap man that you tell me but what is the limit of the stock ecu? Maybe the limit of the z32 mafs!

You mean Nomura's R34??? Blitz D1 car has stock ecu??? A so expensive car has stock ecu? Are you sure about this?

What horsepower it has?

I will go definately for stock ecu!! Nomura have... why not me too??

[paulr33]

if you have local powerfc tuners, then this would be a good choice

up until this year yes it had std ecu (now MOTEC), 550ps around about... i reckon a bit more. i speak to BLITZ quite regulary and help do their local product development here is a pic of the owner and the overseas manager (two jap guys) of blitz at a drift prac in melbourne.

while the stock computer is great, I don't understand how your tuner can supply launch control through it - it is just not built in.....

generally launch control is a second rev limit that applies when the car is not moving. PFC base models don't have this either

It is actually one of the easier parts of remapping the stock ecu, depending on the size of the bin file, you can either have two maps on the one eprom, with an external switch, or run two eproms piggybacked with an external switch. Alternatively you can set it up with the clutch switch grounding the water temp sensor, and map it appropriately

That's pretty damn interesting

[GreeceS13]

URAS this isn't Nomura's blitz r34 right?

Can you post some fotos of the engine please?

Duncan I don't know exactly what he do for lauch control... but in my previous engine ca18 with stock ecu I bought from uk a multiboard with launch control.. but it was simple a rev limiter at 4500rpm! I ask him if he mean rev limiter and he said me.. ofcourse no.. launch control!

Adriano the revlimiter map that I had in ca18 (something like launch control) started with handbrake up (relay at the ground cable)

So guys nothing wrong with the stock ecu...! Can manage the engine as safe as an aftermarket ecu!

Ofcourse I will choose it as it is also easy way

[GreeceS13]

Because I didn't believe that the Blitz, one of the bigger tunning industry in the world use in the D1 Nomura stock ecu I try to find if it is true!

And ofcourse it is All blitz projects have blitz access ecu (stock remapped ecu).

Blitz Project R348

Blitz GTRBLITZ know how to explore the potential in the GTR, and have proved it with their latest monster, the R34 Project 348, where they took a road legal modified GTR up to 215 mph on a German Autobahn using parts straight from their catalogue. On the day the car ran, it used 2.3 bar boost (34PSi) and ran 890 BHP...

The 890 BHP engine uses a single KKK turbo charger, 6 x 1000cc injectors, uprated intercooler, induction kit, Nur Spec 'R' exhaust, DSBC boost control, Multi Speed Turbo Timer, Uprated pistons, High performance camshafts,uprated suspension, Blitz Aero bodykit, oil cooler, uprated clutch, Blitz Technospeed Z1 18 inch rims, Brembo 6 pot brakes, and Access ECU upgrade.

Blitz Skyline RB26DETTAll these parts are made by Blitz or made exclusively for Blitz and are available for purchase.

The R34 uses the latest colour Technospeed Z1 rim from Blitz. This unique design of split rim is in a metallic grey/silver colour, and has fine details such as individual gold studs, and a smart Blitz logo centre in matching gold.

The R348 yielded 343KPH which is not enough to break the world record set by the Veilside R34 in Rotorua (New Zealand), but it's still an incredible speed, and it is highly likely that Blitz will continue to strive to beat this awesome record.

You can see the z32 mafs

???? WOT!

[STATUS]

that is not the d1 car but yes it was also tuned by ABE-san. I have engine reciepe some-where for that R348.... a customer wanted the same engine specs in a R32 GTR a few years back.... it ended up at PROTEK to get tuned but i lost contact and never got to see the final result. It had T618Z's on it... i would have prefered to see a T78, K6-900 or T88GK though.

they now use MOTEC M800 as it lacked various niceties (extended peripheral datalogging) were not possible on the std ecu.

[Duncan]

That's pretty damn interesting

+1 good thinking

[GreeceS13]

URAS Blitz has two project cars..

D1 Nomura rb25 that 2008 runs with motec

and

R348 890bhp with stock remaped ecu as in the fotos

Really cool

Do you understand why blitz use stock ecu??

They didn't have money for a very expensive ecu like me? Ofcourse they have unlimited money!

Blitz don't sell ecus like hks, apexi, greddy!

They sell just remapped ecus with blitz sticker..

So they advert stock ecu to don't let the people to pay money for aftermarket ecu that they don't sell.

So as Nomura's D1 car all the years had stock ecu why not to have my car too?

And think about it... D1 car that sure it needs antilag and other abilities of standalones..

Also 890bhp that has the blitz R348 sure they aren't little!

STOCK ECU IS AS GOOD AS ANY ELSE

just out of curiosity, launch control isnt just a rev limiter is it?

i once read that launch control maps retard the timing and richen up the injectors to produce more exhaust gases whilst reving in neutral to get the turbo on boost earlier or reduce a negative vacumn in a manual car! is this right?

thats why we see japanese drag races revving to redline for quite a while before launching with black pops of fuel exiting the exhaust.

can anyone elaborate?

[GreeceS13]

Yes that is the launch control

I don't know how do you mean that jap drag cars starts but I will use the launch control with a pussbottun at the knob..

When I am ready to go I will leave the clutch and the button!

Or maybe I will do it with the handbrake.. with the handbrake up I will have launch map... and when I leave it down the car will start!!

That's anti lag, a complete launch control system combines anti lag with traction control. Anti lag spools up the turbo, builds boost with no load on the engine. If you launch with full anti lag on you will be sacrificing horsepower (too much retarded ignition and way too rich A/F ratios). That's why a decent motorsport ECU is essential, to switch between anti lag and traction control on clutch release. Retarding and advancing the ignition timing to control the wheelspin. The ECU can use G forces sensors to detect forward motion or the ABS sensors to detect wheelspin or simply a predetimed engine RPM that correlates with previously tested maximum traction, or a combination of all three.

If you are truly serious about what you are doing then lose the standard ECU, it has nowhere near the accuracy, speed of processing data, logging and functionality that you will need. Restrict your choices to proper motorsport ECU's, you will need full data logging at around 50hz, anti lag, launch control, traction control, soft and hard rpm limiters, ignition interrupt on gearchange (so you can flat change), data analysis software etc etc. The likely units are Motec, Autronic, Pectel, Bosch, TAG, Electromotive etc.

[GreeceS13]

Gary I don't need all theese super functions! I will never use them.

I will not need something more than Nomura haha!! Or R348 Blitz!

The only functions that I need is a launch control and I will have it.

Two maps on the standar ecu and when I will have the handbrake up I will have launch map.. with rev limit 5-6 rpm and with retard ignition and rich afr.. no too much aggresive because I don't need to destroy my expensive T04Z!
