#1: TU3JP > TU3A ? Author: V9977, Location: Athens, GreecePosted: Tue Dec 06, 2011 5:43 pm ---- How big a hassle would it be to convert a TU3JP setup to TU3A?
As far as I can see, the only difference is electric pedal/throttle body, no ICV, engine loom, ECU software version.
I thought it was the intake different, that's all.
Otherwise surely they would use a different engine designation, not KFW for both.
Anyway, electric pedal/throttle body seems to be light-years ahead responce and consumption wise and newer software available for the S2000 ECU.
Comparing missus TU3A to my TU3JP has really got me going about this possibility, crazy as it might be.

The TU3A is slightly revisied and placed in a range of low spec peugeots, the head gasket fails from 12k to 20k (oil seal left hand sind near cambelt)
No real different to the later TU3 engine, apart from the port engines on pre 2000 being 00-00 and after being 0-0-0-0
Would just be easier to convert over the the throttle wiring
How?

Could you please explain.
As far as I can tell, our 2007 TU3A is identical engine-wise (KFW) to the 2001 TU3JP, appart from the electric throttle and much newer software version in the S2000 ECU.
One goes like a dream, the other seems a bit rough and lazy by comparison.
Both maintained perfectly and resonably low milage covered even though different age.

As surely being the sensor is built on the pedal box housing all the loom will need to be changed unless you fancy hacking into a BSI? As surely the pick up from a fly by wire will be different from a straight electric? How to, i have no idea. I dont oddly do this conversion

No being picky but if they are 'identical' then the only the ecu confiquration is the main point to attend. I personally find the electronic throttle pointlessly annoying on road tests, you get a by far better feel for the vehicle with old school cable, but thats just my opinion
There is a few minor details ive noticed that is different, such as covers and if i remember correctly the inlet manifold (ZAY recalls require health checks and they always fall to me ) is slightly altered too.
Im pretty sure peugeot have altered the engine for the emission regulations now a days (could be just the CAT but who knows), as the standards have ten folded.
Ive noted that these engines in question are by far the slowest piles of w**k ive ever come across. Yes i know cars can be guttless but really?! The original TU3 would happily p**s all over it (opinion again, no facts)
#10: Re: TU3JP > TU3A ? Author: Andrew, Location: Black Country Ay IPosted: Thu Dec 08, 2011 4:18 pm ---- Had my TU3A Rolling roaded and it made 73hp and 75hp, just the same as a TU3JP is meant to make
Lee once said that the compression ratio is fractionally higher on the TU3A, and here are some characteristics of the engine he posted on one of my threads:
"Special features of the injection system :
Transponder : 2 version
Piloted alternator with improved performance (Reduction of consumption)
Piloted thermostat
Engine phase detector : Incorporated in the compact coil housing
Sequential injection
Twin static type ignition
Air temperature sensor incorporated in the inlet manifold air pressure sensor
ECU supply : Double relay incorporated in the engine fuse box (BSM)
Engine cooling function : Incorporated in the injection ECU
Accelerator pedal with integral sensor
Motorised throttle housing
Special features of the fuel circuit :
Injection rail without fuel return
Fuel gauge/pump module with integrated fuel filter
Special features of the emission control : No recirculation of the exhaust gas.
Special features of the air conditioning : Air conditioning pressostat (Linear sensor).
Special features of the engine cooling system :
With air conditioning : Dual speed fan assembly
Without air conditioning : Single speed fan assembly "
I am guessing it is slightly detuned compared to the TU3JP because you would expect the higher compression to make more power, but it is designed for the Euro emissions that came into affect for when it was launched. Also the cat being on the downpipe, probably strangles gas flow compared to the old undercar setup.
As for head gaskets, I've not had a problem *touches wood* Last edited by Andrew on Thu Dec 08, 2011 4:30 pm; edited 1 time in total
#11: Re: TU3JP > TU3A ? Author: Addaz, Location: SuffolkPosted: Thu Dec 08, 2011 4:29 pm ---- I would check the history of the car mate, as its roughly 3 or 4 a month now
With about 7 or so being reported internally
#12: Re: TU3JP > TU3A ? Author: Andrew, Location: Black Country Ay IPosted: Thu Dec 08, 2011 4:33 pm ---- All history is with Peugeot Dealer and I asked for my history: it came back with two intermediate services and a class A
Are they being brought in for head gasket problems, or inlet manifold safety recalls?

OK. Cheers for the info.
Please bear in-mind the type of use over here;
City driving, fuel economy, low-noise and stringent emmisions testing,
small parking requirements and cheap.
The 1.4 206 is very popular car for these reasons.
It's so common you will see one every couple of minutes on the road.
I know it's slow as I've driven cars that.. go quite nicely.
However I really think the ECU software is much more up-to-date on the TU3A
and having recently gone to Pug dealers, there appears to be no newer update
(they reccon) for my 2001 TU3JP. (last update March 2003)
I have driven both cars extensively now and I'm sure the map and calibration parameters
have just not been updated/optimised as they have for the TU3A setups.
And I'm taking the electric throttle well into account in this evaluation.

Exactly.

Now you're talking.
That's exactly what I've been thinking.
I'm going back to dealers next week. If there isn't an update, perhaps there should be one.
They've already got in-touch with Peugeot France but we're not done yet.
