Hey yall,

Been a thought iv had for years, thought it would be worth to throw it out there.

Say im looking for something more from a BNR32, what would be required to get my ATESSA up to scratch. Using a G-force sensor bender is a bit old hat, and doesn’t change the fact the system is clocking 10 times a second.

What do you think is required to get a R34 / 33 system into a BNR32?

Would the diff chassis lengths (hence torque application software) make it not work? Would i need to change transfer cases, or could simple ECU and sensor changes suffice?

Thoughts, opinions flames???? :yes:

an alternative could be to get a GRID dancer controller or hks ETS controller and upgrade the 4wd clutch packs to make it stronger

you could also look at locking the pump on via a relay interceptor if you have the vspec system (i did this in my gtst)

Yah, unfortunately,

The ATTESA system as a concept is one that’s used now by most of HiPo manufactures like Porches etc. I don’t want to lock it solid, front to back, nor simply strengthen the clutch packs, Iv never driven a R34 GTR, but am told the system is a lot more progressive and adaptive to wheel spin, and how tight it push’s the packs together. You can watch from footage of quick examples how it effects the attitude of the car (understand the E-diff has a role here, but lets leave that out of the equation for now)

Any other thoughts

Is the R23 V-Spec II a 1000/sec ecu, or was it just a retuned 100/sec ecu? The probelm I see with a R33/R34 ecu is that they have 10% always going to the front wheels, and if you put one of those ecu's in a R32, it would expext 10% to always be there.

Our Targa car has a HKS Kansai controller, no idea how good it is cause we've never turned it on (came with the car), if anyone has any english instructions i'd appresiate it.

Unless the controller replaces the attessa computer completly it can't refresh quicker. I've never seen the Bee-R ones but the grid and all the locally made ones like ours leave the standard computer in place

Stupid question..

but..

Why?

This does answere MANY MANY questions! I went staggy RB25 + ECU in my GTS4 and.. GUESS WHAT!?!.. 10% all the time..

..ghay..

Any way you cans stop/change it?

I think the trasferbox is designed diferently. As you have to remove the front shaft to dyno R33+, and not just the ecu fuse. well 10% is sfa in the grand sceme of things, i assume it balenced the car a little better, and it would make the attessa feel more responsive. The R32 one can feel a little slow at times.

Did you do the gearbox/trasfur case with the engine and ECU?

      Turn signal wiring question

      By Duncan · Posted

      That may not be so tricky with a changeover relay (again, with LED indicator only to reduce load on existing headlight + source)  30 to indicator + globe side 86 and 87 to headlight parker + 87a to original indicator + chassis side 85 to chassis/earth repeat on each corner, sorted, no diode required

      Using Trickle Chargers

      There might have been some "hard core" decalcification going on in the cells to create that noise As for chargers, I stick all our cars on a trickle charger every few months to "clean out their pipes/cells", the Mrs battery in her Mistsu ASX is still running its OEM from new battery 10 years on, and that thing does alot of short drives, and it can sit around for ages without a good long run

      I'm not sure the diode only will give the desired result. I'd probably approach it with a couple of relays (And you still might need a diode too!). You need to be able to break the constant feed from the headlight to the orange corner globe when the indicator is flashing. Not knowing which Skyline we're talking about specifically here too (And it may not matter, but I don't know the R34 column switches) you'd likely need to rewire the stalk, so that the indicator power itself no longer runs through the stalk too, as now you need it able to trigger a relay that will break the constant supply from the headlights to the indicator, then you'll need a separate relay to trigger the indicators to come on (Replacing the internal action of the indicator stalk).

      Import insurance in 2025

      Weird story from me My Toyota 86 was with Commbank comprehensive but for market value (who they use to underwrite is unknown) When I munted it beyond financially viable repair in 2020, rear end smashed in to the point it bent the rear quarter and roof, they knew I paid $31k cash for it because I told them, they still paid me out $38k, as all the 2017 limited edition variants with typical Km and condition were going for between $36-41k, so they did weird math and came up with $38k I never officially mentioned any of the mods that I had done, but as they were not the cause of the crash they were not fussed at all, the insurance inspector actually asked if I wanted to replace all the mods with the OEM stuff if I still had it laying around before they took the car I still came out of it behind though, because I had probably dropped $20k in it with the suspension (bent after the prang), wheels (bent as well) and "other" mods, that the inspector asked about But still, as the market value was higher than what I initially paid, and they paid out market value To say I was surprised with the outcome would be an understatement  Weird, but true, but probably just lucky with the inspector on the day I guess  Sadly, I don't think if I munted the old NC1 MX5 I would get the same result Meh, pay to play

      Well, the car is back, all straight and shiny, for how long for is anyone's guess  After picking it up we went for a bit of a drive, Jebus I really enjoy driving this little thing, hopefully the weather let's us go for a nice long cruise this weekend as it will be out of my hands for at least a few days next week when it heads back into Mania on Monday It's weird, whilst I do always enjoy going for a drive, the NC makes me feel like a kid who has just got his first car, and they just want to drive wherever and whenever they can I really need to look into the MX5 Club of NSW
