Has Anyone Tried To Interface A Larger Screen On A Pfc?

[Adriano]

Hi, just wondering if anyone has tried to wire a 4 or 6" lcd screen into a pfc hand controller, my old age makes it hard to read after 2 hrs on the dyno, plus it would be cool to have one fitted in the dash?

[paulr33]

if you can find one with the right voltage and input i dont see why not

look in the PFC faq in my sig, someone found a suitable screen replacement on the rx7 forums

Better yet, get a Datalogit. Use a laptop and full size screen, and access further capabilities of the ECU.

this man is correct.

The laptop tuning side of things makes the job 1000 times easier. Seriously.

I agree that the datalogit makes it easier to dyno, but i dont want to have a laptop sitting in the car all the time. It would be good to be able to display 2 or 4 gauges on a smallish screen for easy viewing when driving.

[paulr33]

it would be good if you get an rsm style screen for the PFC and plug it in

then you could choose between digital guages, didgital output and have it closer to the driver. the rsm is ace, if only it could show knocking

yeh be pretty sweet to have it on a 7"lcd screen from a dvd player im sure it could be done might need some interface program

[Adriano]

Does anyone have a broken hand controller, my electronics mate reacons he can do it but he needs a part number or a look at the original screen, will pay $$

[sinistaGTR]

keep us posted on this adrian

yeah ive got a busted 26 controller here

actually ive just looked at the unit in the powerfc FAQ and it looks the same as the one used in the hand controller ive got open here on my desk

the one inside the FC controller has a 20 pin connector with A and C on the right hand side like the one on the site here

i didnt realise they had a common 20 pin connector, i thought all the crap on the back was part of the FC

it appears all the crap behind it is the logic for the LCD display. ace ill order one of those screens (out of stock) and wire it up to my working 25 controller

i wanna put it on a safc stand and have it next to my rsm, so that knock is more visible

But instead of using ECUTalk, run the PFC software on the laptop with readouts on the indash screen and only pull the laptop out for tuning purposes

[paulr33]

the main board for the LCD display has 3 chips on the back

all hitachi chips with

5L1

HD 5

61202TFIA

Japan

The board has SII with a black dot

also has E91964 340 in white print

REV B

G1216

B1N (in a white box)

on the underside of the backlit display i can see

020596 in big black numbers

and in small gold numbers i can see D2161

[paulr33]

ok ive just realised

the part no the FC board is G1216

the part on the seiko site is

Seiko 128x64

G121621V000

so it sounds like the same unit

let me order one n see how we go

[paulr33]

ive ordered one of these

The lcd needs to have the exact same controller or an equivalent as the original LCD otherwise the instruction set will be wrong and you won't get anything at all.

Because the original LCD is 128x64, you can't go any higher in resolution without going to a different controller. You might be able to go up in size but keep the same resolution but not by much.

Only way I can see you getting a larger display would be to figure out the powerFC serial protocol (datalogit and the handcontroller would use the exact same protocol) then program a microcontroller to get the data and put it on a larger display.

Is the powerFC datalogit cable USB or serial? If its serial it would have to be an asynchronous serial port. USB it could be either.

If someone has a dead powerFC I'd have a crack at it. It just so happens I have a graphic lcd in the mail

If anyone has any electronics questions about it... just fire off a PM and I'll see what I can do

[paulr33]

well i hope its the same controller logic, can only guess and try it i spose

if it doesnt work its not the end of the world

[R31Nismoid]

Remember what happened last time you "tried" something

*burning smell*

[paulr33]

yeah but thats hacking a wiring loom with the power on

ill have a friend swap the screen over

i cant do that myself, the soldering is too small
