my CA18det is RETARDED

vveecee18 Feb 2007, 20:11

i decided that i didnt actually care if i fucked it, and i moved the cam timing gear to the middle!!!

it doesnt hiccup at all anymore, it doesnt feel as if it has heaps more power, but it feels like it pulls a little more!!!

i reckon its still retarded, although not as much as before its minor untardationnessism!!!!

But if I remember correctly the "pin" is visible from the one side, think its from the bottom because mine was sticking out a bit. Anyone that has pics off a stripped CAS.

Its been a while since I stripped one but the disc has 3 holes one for a locating pin and that is more so you cannot assmble the thing incorrectly. It has 2 holes on either side of that for screws so it is physically impossible for the disc to move once it is fitted.

Even if the pin is missing the screws will still prevent any movement.

Veecee get a timing light and check your base timing it should be 15 deg I have seen a few cases where the base timing needed to be 20deg or more to gte the car to run properly.

I find the best way to set the timing up is to load the car at about 2500 or 3000rpm on the dyno and power time it.
Otherwise use a quiet stretch of roiad and a stopwatch to find the optimum postion.

Here is a pic of the CAS... this one just have a my Wolf3D tigger disk

vveecee20 Feb 2007, 09:30

well there you have it gents...

vlade you resourceful bastard!!! no more arguments. thanks!!!

calibrator - originally i thought that i had set the base timing at about 15 degrees, and i thought that maybe i got the timing belt wrong.

but we checked that, and i am 100% sure the timing belt is set properly.

so then i looked at CAS again - and it cant be. but now i no longer have access to the timing light that i once used to use. until i get another, i'm useless!!!

but i honestly think the car needs to be dyno tuned. i dont think my mixtures are set right, i also am not sure of the fuel pressure at boost (although its about 2.5 bar at idle), we all know about the timing, it would be nice to know that i dont have a boost leak.

it would also be nice to know that i am not running with about 80rwkw like the dog that the car feels at the moment. maybe i'm just used to the power!

what is the stopwatch method?

VVladeadmin20 Feb 2007, 09:53

I might be wrong but there isn't much one can "tune" these cars with... So I'm not sure what a Dyno Tune will help with... Other than setting the perfect timing.

I know you can adjust some mixtures with the MAF sensor but its very very little... Some other peopols at Rightway developments tried to "tune" my car, before I had the Wolf3D... Ended up being a waste of money.

vveecee20 Feb 2007, 10:12

that is what i am worried about!!! a waste of money, its been a concern for some time now, and thats why it hasnt been to a dyno.

but i'm getting fed up now - specially since i lost the use of a timing light because one friend told the owner of the light to "take a hike" *smiles at the use of such lame politically correct language*

i am specially worried about the mixture setting on the MAF.

as none of my brothers answered my calls for help in the 'chat' forum - (maybe coz the technical guys hang out here), so now i resort to hijacking:
anybody out there that can get technical diagrams or schematics or workshop manual kinda things for other cars?
calibrator? anybody?

pref digitally, like our sx manuals
or anything!

car in question is my pansywagon - renault scenic rx4 (4x4)
looking for cooling and electical pics

pleeeeeeeaaaaaassseee!

you see - no-one 'cept daniel here has replied in hours. pretty soon it will be days, then months, then my sx will probably still be retarded!!!!

Vlade, goodness now I am totally lost. Big statement here that I truly dont follow. ๐Ÿ˜ฎ ๐Ÿ˜ฎ ๐Ÿ˜ฎ

most of the bits on the sx engine that control the way engine runs, are controlled by the computer. sensors are not adjustable for the most part, obviously excluding the biggies like the TPS. even the idle control is supposed to be adjusted when NOT connected to the computer.

base timing is set, fuel pressure is set, injector and spark timing is controlled by the computer, you can slightly adjust the mixture if you "dig" open a little screw on the AFM, but thats supposed to be factory set and sealed too!!!!

thats what he means i think!!!!

TThe Calibrator20 Feb 2007, 19:37

There is a very simple way to tune those cars on the dyno.
Its called a piggyback take your pick Unichip or SMT6.
With someone who gives a damn tuning them they work very well.

R2500 fitted and tuned seems to be the going rate.

CChemCooladmin20 Feb 2007, 20:22

Unichip

Duane, I will soon approach you on tuning the sx. Thanks. 8)

vveecee25 Feb 2007, 21:14

seem to recall another thread that mentioned that the smt6 would not fit??? if it can then it may be an option.

found some strange little quirks on my engine this afternoon.

1. the throttle position sensor will advance the timing about 20 degrees when it is unplugged - this happens at idle. if your car is at 15 degrees, then it will jump to 35 degrees advanced??? WTF???

2. there is a method to set the CO levels/mixture ratio controlled by the AFM in the manual specific to cars w/out the cat and w/out a CO tester. tried this because i'm sure mine was incorrect.

3. because my AAC valves and associated thingies weren't working, these were removed and idling is now set mechanically.

4. timing was set according to the manual, which had pictures similar to those posted on this thread earlier. my CAS is still on the retarded side of the middle of the range of motion, but according to the timing light its set at 13 degrees BTC. I HOPE THIS DOES NOT MEAN I AM A TOOTH OUT ON THE CRANK PULLEY - but what would the symptoms of this be??? cos the car is fine for the most part.

ALSO - at the track on friday night, the car misfired a bit at the end of the rev range in second when 3rd gear was about to be engaged. the audience told me that blue flames shot out of the exhaust at the rear of the car. is this bad?

Sorta the reason why I went standalone...

My old management will work fine one day the next there was all sort of issues, check the ECU it would say its fine... Then wham it run fine again... My timing was always all over the place couldn't figure out why.

I'd say try double checking everything, like timing belt and so... I know the FICT valve (one for aircon) can fuck one around with the idling, previously before my standalone my plug would fall out, during a drive, then at the robots bam car won't idle.

Flames are cool ๐Ÿ˜‚ On my old ECU, my car would throw a huge flame during high rev gear shifts, it was a huge orange flash every time I shifted on top revs... freaking cool ๐Ÿ˜‰ But the car was over fueling a hell of a lot. I can remember dicing a Supercharged Yellow M3 from RGM (I wasn't much of a challenge) but the guy really liked my car's sound and the flames during our little 200km/h run from PTA to JHB.

can fuck one around

thats almost where i am at, at the moment. i'm tired of being fucked around!!! i figured if i went through everything then it would be ok, but compared to other guys cars, my CAS visually looks retarded. and other guys seem to have more power!

i checked everything yesterday that has to do with mixtures, timing and idling, and all i can think of is that maybe i got a tooth out on the crank pulley.

but i'm really not "luss" to go messing around down there. maybe later!!!

CChemCooladmin26 Feb 2007, 08:41

This one is also a previous thread under timing or so. ip, the same happend with me. Adjust the timing according to maqnuel to the book. You set it now, you check it later, it is different. Somebody said the ecu is not self learning etc, etc. Still up to date I dont know how to take charge of setting the timing, because of the above. Last time my timing was set by the tuner and end of story. ๐Ÿ˜ฎ ๐Ÿ™„ ๐Ÿ™„ ๐Ÿ™„ ๐Ÿ™„ ๐Ÿ™„ ๐Ÿ™„

VVladeadmin26 Feb 2007, 09:09

As far as I'm aware our range of ECU's don't have a learning capability. It's got a straight binary table that it looks values up, and then a huge number of input variables that affect the output.
