my 86 is sufferning
 

sorry not sure where ksa is located. is that south africa

is your fuel 95 RON.??
yes it does rearly need 98RON fuel for best performance and smoothness.

do you know what ecu calibration id your car is like ZA1JA01G.

IF your car was made before mid 2013 it may have an old ecu calibration and dealer should reflash if you have idle problems.

suggest you take to dealer and get them to check

we only have 95 RON here in SA and our cars seem to run ok with them, even though the fuel flap says 98 RON only

thats correct it will run ok but at reduced performance.
if you have ecu logging device have a look at your IAM its probably about 0.5 or less and you will have sognificant knock although you may not hear it.

you guys run same ecu calibration as here in australia and i have seen stock cars with IAM of 0.7 or less on 98 Ron fuel and knock correction of 3 or 4 degrees.

however the original poster apears to have other problems possibly related to early ecu calibrations such as 700 900 or A01 ecu calibrations or the cam actuator problem if his car is running that rough and stalling and idle dip and stability issues.

KSA=Kingdom of Saudi Arabia

wow thought those guys would have great fuel.

sounds car has a problem though if its under warantee should take it to dealer

Unfortunately, my friend KSA is not as many people imagine

Is the use of 95 will damage the engine....؟
Or just about losing power.......
I need to solve problems ....Or may be forced to sell:cry:

And I will make sure of the date of manufacture of the car soon

The use of 98 is recommended the use of 95 is required so don't think you have a fuel issue. Since mine is a daily driver and I am not worried about top performance I run 91 (the NA equivalent to your 95) pretty much exclusively with zero issues.
Like has been said already get you ECU flash level checked as that is more likely your problem.

You could always add some octane booster at every fillup.

I really need to try this, with some good octane booster, on a hot day you can feel a serious drop in performance

so what you are saying is that with the knock you mentioned above, this will actually affect longivity of the engine?

theowners manual recomends 98 ron fuel for best performance , it also states 95 ron fuel can be used but it will reduce performane ue to the ecu pulling timing when it detects knock.

the ecu should control knock well enough to prevent engine damage.

however if your car is stalling and idling erraticly this is likely to be another problem and you should get that fixed

Good morning

my car date of manufacture JF1ZN12........

Tomorrow I will meet some friends All of them have 86 We will Cheak the lgnition coil

that number is vin or vehicle id number, what you need to know is the ecu calibration id you will need an obd scanner or similar to read cit from ecu.
if your car is pre mid 2013 manufacture there is likerly an updated ecu calibration the dealer or you can flash.

95 octane is fine. The engine will adjust the timing.
Also, the idle RPM without A/C is only 650 rpm so 800 should be ok, unless if it is fluctuating all the time.
If the RPM is fluctuating without A/C and check engine light on then bring it to dealer!

I think i know what is ur issue. U do u feel like poping when you go WOT between 2500rpm and 5000RPM ?? . If yes change ur DI as a set

Hey
What is IAM ??

How do i know my ecu not updated . Mine is ZA1J700J

IAM is ignition advance multiplier, you will need an ecu logging device to see it or techstream software.

700J is an old calibration, latest one for that model would be ZA1JA01J

that old calid will not have the DI seal fix or the lastest idle dip fixs. you dealer should update it for you.

if you have a flashing device the updated rom is at end to tactrix ecuflash post link below

I will discuss these responses with a friend in the workshop this evening

And I'll tell you if something new

CEL code ??

Good morning
Sorry for the delay

After you return to the history of the Cheak Engine

i got


p0113........intake air temperature circuit high input

p0017........crankshaft position -camshaft position correlation (Bank 1 Sensor B)

p0102........ mass air flow circuit low



And this is a reaction to the lack of octane in gasoline.....

Is there a possibility of programming the car ?

The car is under warranty, right? Take it to your dealer as soon as possible.
I'm no expert, but if I got a P0017 I'd be worried.

as previous guy said take it to dealer Asap it looks like you may have a problem with the cam vvt actuator and also possibly maf sensor as the temp sensor and maf sensor are in same package in intake tube.

Good morning
Unfortunately, does not have anything new about the problem

I must updated the car computer my is (A01)

The local agent does not respond to Emails

The Ministry of Commerce procedures take a lot of time.....It is responsible for customer complaints.......



Is there a way in case of failure of all attempts......Is there a way to get the programming outside the agency TO (A02)

You could flash that update yourself with Tactrix Ecuflash updaed rom attached to post see taxtrix ecuflash link below or buy openflash tablet its easier to use but more expensive see links below

Id buy the Open Flash Tablet. It is relatively cheap and offers so much. First it would ( or should) solve your problem. Second, you would be able to find tunes for different fuel sources. third, data logging capabilities so you can see what your car is doing and feeling. Fourth, you can check and clear check engine lights.

those are the four major points that sold me on the device but there are a hundred other things it does. My car had an idle issue on the stock tune and would almost stall out without the AC on. The dash lights would all come on and the radio would kick out. Solved by flashing to 91 oct map (95ron equivalent?) and when i want more performance I can add an octane booster and flash over to the 93 oct map (98ron?)

Good morning

What's New in thes issue........There are plenty of car's affected , Were sent a detailed email about the problem to the dealer....... After a month ....Person in charge Was on vacation.....!
he says,i will see and speak on the topic of Directors.....!


We are now on the process of gathering the largest number of owners To provide a big complaint

Because patience has ended ....We want a solution

Open Flash Tablet........Is an excellent idea ... but I'm afraid that the conflict with the old programming A01 ,If he was able to replace the OLD MAB I will now calling I WILL Buy it now

Good morning

The agent replace the old ECU .....And things are excellent at the moment
I will continue to experiment for a week

But I want to make sure of the Calibration ID :mad0259:

buy elm327 adapter
