New toy WILL play :-D

Are you sure, as the dash, seats, lights and the inlet manifold, as far as i can see, is all S4

[grinder]

really .. hummm !!

was speaking to Pip and he asked how the IC fastened on - and he said that it was an S5

the front bumper is a S5 aswell ?

is there a clear way of telling a S5 from a S4 ??

under the bonnet looks very very similar to mine

im interested in the dash comment - as its identical to the coupe that i have ( and im sure the 88 cab had the same dash aswell )

well this makes it a more interesting thread

John, Which pics have you seen? (think Stu needs to update his web page )

Stu had a White S4 Vert, this is a Green one that has S5 lights in etc.

[Grizzly]

Mr Grinder man.

Do you have any recent pics of the engine etc just to make sure its a S5 before you go buying stuff

[88GT-R]

Need more pics, but looking at the engine, the coolant elbow is ali and has a cap... S5 is plastic no cap. The mirrors are black, and most importantly the side mouldings are also black. S5\'s are all colour coded.
That there be a S4

You\'re looking at the wrong one.

Yep, But you can\'t tell alot from those pics, Ok its the Right year for a S5 and it does have round lights but you can\'t see the Seat type,Dash,Engine??

Would\'nt be the first time a S5 has had a S4 engine put in???

But if i had to lay money on which model it was S5 would be high on the list.

My bad...Stu update that damn website!!!!
Green one looks a good old S5! I will try read all this thread, and see if i can help.

John, sorry I misled you on the phone! I had S4s on the brain!

[grinder]

you all had me really really really worried then !!

yeah the white one now belongs to turboIInuttah

i will get round to updating the website when i have chance

gonna speak to rxmotors and see if they have a N374 ECU - and have someone else looking for one at rotechnics

if all this fails ... errrr ...... cab for sale ?? LOL

Stu,

I have managed to cleanup your old ECU, need to test a couple of the components with a meter tonight and make sure they are still within tolerance, but it\'s looking good - if all goes well, I will blow the code from the Knightsports onto a blank Eprom, and pop the ECU in the post tomorrow for you

I have also sprayed the board with a silicon coating formulated for electical use.  Should provide an additional barrier against moisture problems !:Giggle

[grinder]

prof - can you check what was on the chip ??

does it look ok - or could the chip be at fault and we have carried the problem forward

found some more info on ECU types aswell :

RX7 - FC3S    
88 - 91
13BT
N340
rev limit - 7500    
manu - Mazda

RX7 - FC3S    
88 - 91
13BT
N340
rev limit - None    
manu - Mazda

RX7 - FC3S    
88 - 91
13BT
N374
rev limit - None    
manu - KnightSport

not sure if that helps us or not

[grinder]

from lots of digging around - it would see that a N380 should work just fine as this is Jap/Euro Spec

now the 380 is fitted to UK TII\'s - looks like im ripping mine out the TII !! LOL

Prof : dont send the ECU yet - let me check out the coupe one - if this works - then pip said he has some - if it does work - looks like the Knightsports chip could be at fault

only thing im thinking is when its running on idle - it uses a base map - when you floor it - it switches to the chip for info - now then - tony said it idled fine and when he reved it - it cut out - so based on this wonderful thoery - has the chip gone faulty - he reved it - and blew the chips ( or something else )

its something else to consider i suppose - if the weather holds - might try and get the 380 ecu out of mine tonight - shouldnt be a big job - and the ECU area on the cab is wide open as we have been testing it

2 things can happen

1 - it works - and then we can all sit back and laugh
2 - it doenst - and we havent really lost anything - just proves that the the ECU is A-OK
