Swapping 5A-FE in charade 86

[ahsanonline]

sir there is one last problem(i hope)...speedo meter is not showing correct speed...i hit limiters in 2nd gear...my speed should b near 100but meter was showing just 60.....what should i do?

Did you solve the VSS issue you had initially? I think they might have put a different speed sensor in there - one that has fewer teeth or something like that.

you mean 5afe is dumb?

and stupid also

Thanku so much sir for the concern....appericite it :)the problem is solved and as i was thinking it was coz of faulty FPRbefore i reached there they(mechanic and electrition) changed every thing plugs, plugs wire, distributer, ecu, fuel pump, injectors, MAP sensor, TPS, and what not....i reached here and told them to change FPR and they were like "sir ya kabi kharab nahi hota"and started there diagnosing again....they changed the whole wiring, wired all the sensor openly and place ecu in the hood and there was no single difference in the behaviour of car...i insisted them to change the FPR again like "yar maray kehnay pa ek dafa badal k to deekho" so they finally changed it and car was back to life...and then everyones mouth was shut....there was no mis firing...and sir it was not exact 4K the problem startes as soon as we push the accelerator a bit fastly...but this was only hapening on moving car...on standing position it was going till fuel cutoff limit...it was ideling was perfect..and there were no error codes....

wait a bit more and you will find some real wild a$$ mechanic guesses too - they are exceptionally great with automatic transmission diagnosis, I have repaired a 4AFE AE101 GLi corolla automatic that would not shift out of 1st in less than 30 minutes. The usual diagnoses was transmission change to a tune of Rs 25000/-

bleh, I just removed and replaced the governor assembly, it was jammed closed with contamination.

Is that 800rpm idle (with no electrical load)? Or is it 750?

It idles at 800 or little below it but bcoz its on CNG so some time its at 750 and some time 800. With ELS given positive it jumps to 900 and with load comes back to 800.

7AFE ECU is little better than 5AFE. Even if you dont connect ELS turn on all the electrical load, Brake light / Blower FAN on full / Radiator Fan/ It will drop to 600 and slowly moves back to 800.

like Sharo I also had a issue it was not FPR but only STA was disconnected from some where in the wiring and it gave nightmares to my mechanic and electrition They did everything they could to solve the engine running in limp mode. I had to take my car home after they were scratching their head with no clue :p.
In Limp mode the car gave me 4 KMPL Petrol average. But later fixed it by my self (Thanks fo Xulifqar and Farrukh)

[Vaqas1]

^^ That's On 7AFE.....5AFE Respond Same??? The ENd MODEL A Series Have Better ECU's......(One With Black Stickers)

The Earlier One Are Just DUMB...!

Yes my 5AFE use to do the same. But after I tried different ECU only one behaved like above all others had no idea if there is a some connection to ELS.

Yes a friend had a Honda civic 2005 it was running to bad no pick no nothing and missing very badly. The honda people said the Map is faulty so they quoted a high price for a new one we went to 2nd hand market bought one for 300Rs Tried 3 or 4 but no difference. So tht guy refered us to a Electrition Ustaaj jee. First he kept us waiting for 25 mins than he came checked the car and said 8000Rs ka kharcha hai and you will have to leave the car for one day with us we will open the whole wiring and check.

We refused and came back. Tried one more guy a cng tune up one. First thing he did was disconnected the advancer and car came back to life :p.

thanks bro..that problem also solved...the problem was with the meter...the meter maker guy solved it...

LOl...seriously these mechanics dont know what they are doing...

[Sharo53]

swap completed...
uapdate and pics will be uploaded tomorrow..INSHALLAH

Same As My IMC 4AFE ECU.........Stupid And DUMBArse...

Simple Stuff......Replace And Check Their Best Diagnosis...They Will Always Be lakeer Ke Fakeer.....Not A Thing Above That

LOL...That Was Nasty Back In 2010?? 2011 I Guess.....! STA Signals Is Always A Backstabber...Show No CEL And Create Mess BIG WAY

[SER_GTR]

With These ECU's A Manual Diagnose Is A MUST.....!! You Can't Just Depend On CEL.....

my 4AFE Is Acting Weird Also......Sometimes It Cranks Up All FINE.....Sometimes It Just Denies To Start...Then Start...MISS Miss Badly
( 1 or 2 CYl Not Working) Then After Sometime It Works Fine.....! Spark Is All There When Check Always Manually

Dizzy Checked...Coil Checked...Pickup Coils Resistance Check....Plug Wires Check And Replaced ......Plugs Cleaned...TPS Checked Calibrated To Spec....Timing Adjusted...TB serviced....Injectors Cleaned And Serviced....!!

Once It Start...It Drives Like Charm...No Issue Whatsoever.....In COLD Starting Like After 12+ Hours...Miss A Bit Then work Fine

After 4 5 Days or A Week It Does Same...No Starting.....Takes Forever To Start....Miss Miissss Start (1-2 Cyl Off) Then Gets Normal After Sometime...

Fuel Pump And Pressure Is The Last Thing To Check.....Removed Fuel Pump And It Was All Covered With GUNK RUST...Clean And Put It Back......!i Doubt Its Working On Full Pressure.....Maybe Causing issue....

[Sharo53]

The ECU

injectors

plugs

adjustable strutbar under the car

3rd mounting under the car

READY TO GO HOME

[SER_GTR]

Replace Injectors O-Rings.....And Clean Them...Service Them....!

The ECU Looks Like Of 95 Model 2nd Gen 5AFE.....Same As You Have....

2 ELS Points Can Be Seen....

[Sharo53]

new rings are easily available from spare parts shop?

how to clean and service them?
i had to remove throttle body intake manifold first to remove injectors..right?

u were talking about this ecu, this ecu is dumb right?

[SER_GTR]

DUmb Means Its Not So Intelligent Compared To Newer Model Toyota ECU's......Forget It....It Will Do Fine...as Long As You Wire It Perfectly

Yes...O-ring Kit Is Available...Each Injector Have 1 O-Ring And 1 Grommet Ring And 1 Vibrator Insulator RING.....!

Ask For It It's Available Easily....

No Need To Remove TB ...These Are Top Feed Injectors And You Have To Just Remove Fuel Rail And Some Fittings To Get Them Out..

There Are Desi Ways Of Cleaning Them.....They Do It By Opening Them Manually(Using 6v Supply) And Spraying TB Cleaner Through It Couple of Times....!! Reverse And Front Side...!

If Someone Have Injector Cleaning Machine Then Get It Cleaned From There

[Vaqas1]

To clean injectors you will need a ultra sonic machine no other way works. In Lahore there is a shop who got this is Magic Motors. Below is the map to there shop.

https://maps.google.com/maps?hl=en&ie=UTF-8&q=magic+motors+lahore&fb=1&hq=magic+motors&hnear=0x39190483e58107d9:0xc23abe6ccc7e2462,Lahore,+Pakistan&cid=0,0,18283381220777502955&ei=GpYXUJCQIYTrrQfiu4HwCg&ved=0CJABEPwSMAE

TO take injectors out of this engine is bit hectic. You will have to remove TB and also top of the Intake than you can take out the fuel rail and injectors.

This ECU got 2 ELS but I dun think any of these will work You can try by giving 12+ to the ELS point and see if it makes any difference to the RPM.

I Clean Mine Making A Small Apparatus ..Complete DIY

Works Well For Cleaning Most Dirt Out Of It....!! Work Well For Me ..Do It On Sunday Myself As I Have No Time Spending Almost A Day AT Injector Cleaning SHOP....With Handsome Heavy Charges ....!

Ultrasonic Cleaning Will Make It All Clean But Make Sure To Get Them Flow Tested Also Then.!

Before Spending On Cleaning Injectors..DO Check The Injector Coil 1st That Its Worth Spending On...!

@Vaqas...How Much He Charge For Injector Cleaning And Flow Testing??

[Sharo53]

Thanks vaqas bro for the location...
I'll contant him when i'll get free..for now im running after interior cleaning and rust care
