VIN not decoding; seems to be incorrect.

Inception:


Yes sir.

But it was first replaced with a wrong one from a 2011 kia sportage (same outward looking transmission, but different gear and final drive ratios)

Clunking started immediately car was driven. But the nail on the coffin was that TCU adaptation was reset to this transmission . It first drove very smooth for about 30km and of course it went back to limp mode again.

Transmission was later replaced with the correct one (after serious research) and TCU reset, But this time only 1-2 was smooth with serious flares at other shift points at WOT. This persisted after transmission was exchanged with at least 4 other gearboxes of same spec.

Not sure where the 3500usd came from. Drew Tech that is arguably the best is below 1700usd.

If it has to be done, it has to be done. There are problems you CANNOT solve without reprogramming. At some point, you will just start offering the service. If you don't want to spend money buying your own hardware, there is a way around it, but your customers end up paying more.

If you get someone to flash your ECU, ensure they have very good internet to avoid damage to the unit.
In some of these cases, it is a hardware fault and re-flashing may not resolve it. Further investigation will need to be done to verify this.

Post ECU part number. I may be able to help you.

It is correct sir. Pls see link of detailed specification of vehicle:

Maxi Sys elite with 2yrs free update sells for 3500usd inclusive of the j2534 box. After expiration of the free update you pay 1350usd . To navigate through the delearship server you pay the appropriate fee depending on what service you need. Ford for instance do not joke with this. Each time you log in you are charged exclusive of getting a pass thru software from their server. With the aforementioned what do you think should be an appropriate fee for this service on the Nigerian soil

You don't need Maxi Sys Elite to program, but you need its J2534 box. This can be installed on most WinXp and Win7 laptops and hooked up to the vehicle's OBD. Apart from Mercedes and BMW, Maxi will not fare well. You cannot program Hyundai with Maxi; you will need their software on a PC, and subscription. Those OEM programs don't run on Android, which is Maxi's OS.

My point here is that with a good pass through, PC and subscription, you can program. Leave Maxi out of the equation. Discounting the subscription, hardware will not cost 3500usd like you stated. Autel's pass through is 800usd, which can be purchased alone. Add that to another 700usd for laptop. That is 1500usd. Then you pay for subscription. You can even do pay/day or week or month for some manufacturers. Since you have the device, (and most likely a laptop), you are almost there. You don't need Autel's update subscription to program.

On the amount to charge, it depends on your business model, but on-the-fly programming (where you don't need to pay subscription) will cost you, the technician around 43k per job, irrespective of brand. There are other details.

The bolded is very wrong. Maxi Sys comes in various how do you intend to programme ICM for bmwF10 without autel's on line subscription. You would never get that possible. How do you intend to programme an ism for Benz GL450. With out the autel's subscription you would never be given access. It's something am currently facing now and that's the reality. Only using my BMW icom for beemar jobs now

You are getting it wrong. If you are using Autel pass through connected to a laptop with OEM subscription, what do you need Autel subscription for? Are you saying you must have Maxi Sys before you can program outside of Maxi? You are only limiting yourself to BMW and MB if you are sticking to Maxi. Of course if you don't have Autel's sub, you cant program with Maxi, but not with their pass through. How many MB come to your shop for programming? There are more Japs on the road, and Maxi Sys are useless with those.

And if you have many MB and BMW customers, why not pay for Autel's sub and charge accordingly?

It was setup cost that triggered this debate.

mayor2013:


Have you by chance used this tool. I thinks you mixing things up. I think you should use this tool so by then you would be able to change your mind set. Most European vehicles the maxi Sys elite would confidently work on. Not to forget the online programming capability does not require a pass thru for that. You need the autel subscription for this. With this you have two subscription to deal with. Autel and the dealership subscription. Not to forget the maxi Sys family has got a wide variety to choose from.

Kashif:


Yes, I have used the tool. You agree Maxi Sys can only program BMW and MB. When you say Maxi would confidently work on Most Europeans, remember we are talking about computer reflash, and not just setting changes.

What do you mean by online programming?

Na wa for Hyundai Kia sef...

After exhaustive investigations and research, i realized that even the transmission replaced is not compatible! The TCU was never at fault.

The Transmission installed was from a KIA optima 2012 US spec vehicle. All drive ratios with the originally designed transmission is the same( gears 1 to 6) but the final drive ratio is different (2.885 for US spec{2.4 GDI engine with 200HP output} ) as against 3.367 for the 'General' spec{2.0 Theta II MPI engine with 162 Hp output}). The general spec is the Nigerian export which Kia motors Nigeria sells .

The implication to this is that the output speed sensor takes readings from the gear teeth from the final drive. Now this already gives a ratio of 2.885/3.367= 0.856 which causes a transmission flare particularly for gear shift 2-3 and 4-5 (as this involves the engagement of clutches instead of brakes) .

Now to my gurus: i am in a dilemma. i have a 2013 Hyundai Santa-Fe gear which i dismantled and removed some elements (clutch disks) for future use in case of clutch pack failure( long story for another day) . upon checking i realized that the final drive of this is 3.648 { 2.4 GDI 2WD}. i have confirmed that it will work if i swap the differentials, the final gear and the output speed sensor into the current gear( i don open that one too but no pics you hear ) This will give me a ratio of 1.083.
What do you think?

N.B. This is purely from an engineering stand point and yeah yeah i know i will need to buy another gear but i want to be like kashif first and use my leave to have some fun

No vex ooo make I ask question.

1. How did you arrive at the initial conclusion that TCU was faulty?

2. How did you arrive at the initial conclusion that the first transmission was not the right fit and that this other one as well is not a right fit?

3. You said you are in a dilemma, but the issue is not very clear? To install the 2013 Sante-fe transmission or to ....

Seems to me that the issues discussed are over and above the capacity of a shade tree mechanic...

Good questions...
1)
Transmission was replaced 3 times after purchase from previous owner(valvebodies was also interchanged. ) with transmissions from US spec Hyundai sonata and kia optima 2.4 GDI ( i knew this from the vin stamped on the gearbox bodies). It was the same story ( transmission flares 2-3 , 3-4 not too bad, 4-5 bad, 5-6 not bad) but with no jerking. Only 1-2 engaged normally. This caused the initial conclusion that TCM might have gone bad.

Remember that the car was bought from previous owner with 2013 Hyundai Santa-fe gearbox(2.4L GDI 2WD) installed as it had suffered gearbox failure from previous owner( forward gear refused to engage according to him). Prior to replacement of gear by new owner, transmission adaptation was reset. the reset caused smooth gear shift with no flares for a bout 20-30 km, then harsh engagement set in (particularly from 2-3)

Vehicle is a Nigerian specification vehicle, transmissions are US specifications

2.
Like as earlier said the first gear installed was from a 2013 Hyundai Santafe 2WD. Gear ratios were all diffrent (1: 4.639,2:2.826, 3: 1.841,4: 1.386, 5:1.000, 6: 0.772, Final drive= 3.648) . The Kia Optima/Hyundai Sonata ratios are(1:4.212,2: 2.637,3: 1.800, 4:1.386, 5:1.000, 6: 0.772, Final drive( US spec)=2.885, Dana spec 2.0 MPI= 3.367)

Vehicle will never shift the same Unless maybe you go the invasive surgical route, replace the ECU with Nigerian US specification and all the attendant problems/costs that would come with it.

3.
Right now i have 3 transmissions... 1 from Hyundai santa fe, 1 from us spec hyundai sonata, 1 from kia optima us spec( currently installed on vehicle). I was able to rebuild the Hyundai sonata from the Santa fe by only exchanging clutch packs. This i have tested on the vehicle and it worked (with the same flaring issue of course). There i realized all the similarities and differences.. So now what i intend to do is to swap the final drive and differentials on the Hyundai sonata and install on the vehicle to check compatibility

Let us know how it goes.

So you are in this trade...as a business or hobby doesn't matter, but I have always had this feeling that are one of us.

The mechanic was simply my 10 -11 spanner
