Flash cable

[steelie600]

does any one have the 2.0 flash cable (cant remember its real name) that i can hire or borrow??

Ive hatched a cunning plan!!

[John TheAntique]

I'm pretty sure I've got one in the car but won't know until tomorrow. If no one else replies PM me your address Friday pm and I will stick it in the post.

[steelie600]

cheers John much appreciated

[Nutter_John]

didn't think yours was a op v2.0 cable John ?

My spare cable is with someone so I can't loan mine out , what you hatching anyway

[steelie600]

now that would be telling, but it involves dynos, vr4's and altered shift patterns!!

TBH ive secured the loan of a dyno trailer from a friend in the motorsport industry, and i want to have a look see if you can alter the shift timings on the box, no reason why you cant after all its only a computer but needs research. If i cant borrow one ill have to stump up but for how long ill need it it doesnt really justify buying it

Mines the one thats got two plugs on the end. Is that the one?

[Nutter_John]

couple of points to help you
your PFL ecu is not flashable , and the auto ecu is not readable via the OP cables , nor is anything known about the internal logic in the TCU

Is the dyno your matey got 4wd as I have only seen the trailered ones as 2wd

both the 1.3 and 2.0 have two plugs , is the wire into the second block permantley attached , if so then it is a 1.3

so a 7202 ecu not flashable eh????

It is mate ive already had a look seems all supers have 7202 ecus, interesting about the at ecu ill have to look into that deeper, and yes the trailer is 4wd, i beleive it is one he has done himself with a normal dyno but built it into a trailer, it aint small its fitted into a artic trailer. So i need somewhere to home it for a couple of days as i cant have it at my house LOL

[Nutter_John]

ah yeah I forgot yours is a almost super

good luck finding any info about the TCU programing as it is only needed for the VR4 and possible the 7 GTA

Thing is that it has fuzzy logic so you'll find it very hard to change the shift points unless yoiu disable the fuzzyness which will be a disassemble and rewrite of certain parts of the TCU

i have a few contacts into ecu programming so ill beat them with questions about it LOL, does anyone know if the mut II can activate the solenoids in the box or not??

oh and mines getting closer to a super it now has canards!!!!! just being blended in and painted now.

The Airtrek guys AFAIK have a uprated 'shift' map thats installed when they are flashed. Its all to do with valve pressure or something. A chap in NZ has documented it i think. let me see if i can dig out a link.

the suspicion is that there is a later TCU for our gearboxes that came out with the 7GTA and Airtrek etc etc

OOOOOO mike, i loves ya. I knew id heard of it on other cars and i was damned sure id heard of it on the gta's too so im sure it can be applied to the vr4. My main concern is i just want instant up and down shifts when in tip, cos when yer getting a wriggle on having to wait for the downshift can get the car unsettled in the corner.

Oh and im also gonna go flappy paddle with it too

[miller]

Have a gander here first off, Scott Lowe is the chap in question. Now wether the uprated pressure came from the TCU or physical change on the box is something i need to confirm.

Just what im after Mike, And it seems we may be able to programme the tc to permanently lock when in tip too so we have a true semi automatic!!!!!

How does that work above normal? Surely in TIP it stays in that gear regardles?

Are our TCU's flashable.......thats the next crux. I presume the Airtrek is. Wonder would it ship into the VR4?

hmmmm

[steelie600]

yes the airtrek is flashable so is the gta, so i cant see a reason why the vr4 wont be either. When i said lock the tc btw, i meant just have it working like a clutch so it only slips when setting off and shifting gear other than that the engine is locked to the tranny. so more power is sent to wheels, gearbox temps will be lower. Looking at the last link Mike, the shift time (presure) and overlap is what we need to adjust for faster more positive changes. the locked tc is gonna be more useful for the trackdayer/ tarmac terrorist (me and you then mike!!)

Just out of interest is there a handling improvement having the one way clutch in the box or not as mine has now got the none owc box fitted from the owc box it used to have.

Might be worth speaking to Mark 4 regarding flappy paddle info: http://www.clubvr4.com/forum/showthr...ghlight=paddle
