Standed Ecu Upgrades

[amordus]

I have hear you can upgrade standed ECU's by loading new firmware onto the eprom chip with new engin maping, Is this true I have a 1994 Skyline R33 GTST.

I think if you remove the kick panel and lie it on the floor, it won't be standed anymore.

ROFL....i kill me !!!

not many people do the rb25det ecu remaps to my knowledge... better off getting a RB20det ecu and having that remapped IMO

While on the topic just a quick question because i can't be bothered searching through 100 posts. You can't run an RB20 remapped ECU on an RB25 Series 2 because of the internal ignitor, correct???

Hm... ive never heard of this problem... keen to hear more also.

[PM-R33]

Pretty much what i remember reading a little while ago is because series 1 has an external ignitor for the coil packs and series 2 doesn't, a remapped RB20 ECU wont run on a series 2 unless you run an external ignitor.

Hmmm i guess i might just do some searching.

Another guy in another thread posted that, r32 ecu was straight plug in.. Only concer is no VCT support..

quote:

no probs what so ever, plugs straight in, however the 20 ecu cannot run the VCT, was no real issue for me as with the remap done, timing changed, boost raised it still has bucket loads of torque down low anyway!

Getting full boost at 2500 rpm, makes 215 rwkw on 0.9 bar with stock turbo. Drives like a dream, smooth clean power with awesome responce!

talk to Dr drift, he does r33 remaps now

[33gtst]

r33 ecu's are now re-mappable via Dr drift. Probably best to drop sam an email..he can certainly shed some light on the options for you.

[Guilt-Toy]

is he using the nistune development board?

[siddr20]

Whats that guilttoy?

If he is using it, is that good or bar? lol

[PM-R33]

Hmmm, the reason i asked about the RB20 ECU on a series II is because one of my mates is a tuner and has a spare RB20 ECU that he could put an RB25 map on and tune it for me. At the moment my car is hitting boost cut/ airflow cut (whatever the hell you want to call it) at 4000rpm on 1 bar of boost on my HKS turbo.

I have 2 options that are possible to do at the moment:

1) Modify a standard actuator to fit the HKS turbo instead of the HKS adjustable actuator and run less boost to avoid the boost cut.

2) Remapped RB20 ECU to get rid of the boost cut and be able to tune it.

Now i know that a full ECU replacement is the best choice, and i will be doing that in the future, just dont have the funds at the moment so im looking at only the 2 above solutions.

So yeah thats my problem at the moment, if i can get the RB20 ECU to run on the series II its going to solve the boost cut problem, because at the moment its giving me the sh*ts.

I didn't know nistune could do the R33 stuff yet.... hmm might have to chat to Matt...

We use daughterboards and real time emulation same as we have on the RB20's for a couple of years now

i just heard that they are testing.. it was on their site. They will need someone to test it for them lol

this is the first I've heard of an R32 gtst rb20 ecu being used in an R33 gtst rb25.

if your in sydney, i've heard hills motorsport does remaps for r33 gtst's for $350

I know, i couldn't help it.

The best was when my nephew wrote down that he "road off" his motorbike after a crash

These are the simple plug in chip upgrades, and to the best of my knowledge CANNOT be tuned in real time, and also require purchase of a new SINGLE USE CHIP every time you want a new map loaded...

The method we are using is converting the R33 to run a single 27C256 eprom, which can be re-used, as well as tuned in real time with full map tracing etc etc... Hence, the initial $$ are a bit higher, but the end results are WELL worth it.

[siddr20]

hehe yea the $$ is scarin me a little.. But i might be a guinee pig and try it out..

so when did you say you are coming to sydney?

Also you got any dyno figures sam? just to see what a similar rb25 with basic mods can acheive..
