Tuning JTD - GSR induction & Red-Dot remaps!

[Argonought]

re: JTD - GSR induction & Red-Dot remaps!

On a standard car they do.
But it was running fine after the rampped, car is happy to rev up to 5000+

I'd love to see you post up your power curve

Be very surprised if you're holding peak BHP much over 4k rpm. What's the point in holding a gear if you're dropping BHP all the time (and that's without considering the mechanical risks you're taking)

My 163HP with standart induction work normal and I can't produce any error... O I get only next error: "Water in Fuel Filter" and I really hate it
My result on dyno:

Next thing what I would like do is induction kit and exhaust, but we must first fix this induction issue

re: JTD - GSR induction & Red-Dot remaps!

the gsr induction has two holes in it (not including the ends lol) one just before the turbo which is for the crank case/oil breather pipe to feed in to. the second is for the maf sensor to slot into it will make more sense when ABZ gets his pictures up.

Haven't you followed the tread or was that a mistype

Remap should function fine with standard induction (as both bozzy and I reported)

I gather it's only an issue with the GSR induction kit :chin:

Well the symptoms i get are the same as Hams and others as we've discussed on Performance Stilo.
Argo, i believe neither you or Bozzy have Reddot Maps, correct?
Therefore mine may function differently to both your cars as would have different parameters entered into the map.

I wouldn't disconnect it completely as the lack of a reading will create a default setting on the ECU which might negate the benefits of the remap and produce errors, so my advice would be to 'play' as I have done and see what happens.

I need to play around a bit more with my 'experiments' to see if this is a definative answer and as I do not run standard induction it would be wrong for me to say my findings are right for every car On a standard induction the possibilities for 'tweaking' the MAF are, sadly, far fewer

Will do and i'll let you know how I get on.

OK - as requested a piccie of the GSR induction, the position of the MAF should be pretty obvious. It's a recent piccie, not one taken today as I've 'mislaid' the bleedin camera

 

[minimad99]

re: JTD - GSR induction & Red-Dot remaps!

ah, so the MAF is vertical on the GSR i'm sure it's horizontal as standard???? could there be anything in that, assuming i'm correct LOL.
If not i'll shut up (waits for replies)

Quite so Must confess, I've got a bit confused over this as I thought the problem was purely the GSR kit but now I realize it's a general problem with RedDot maps.

This is obviously adding a bit of confusion to this thread as other maps (aside from Angel) don't produce errors either.

Have to say, I think you guys need to sort out the original map before worrying about GSR :idea:

You and I are on the same wave length my friend but HOW we do it is the big question.
It would be great to be able to compare Map contents/parameters to see how different companies differ.

Sorry mate - it was vertical in mine on the standard induction

However, the angle of 'attack' of the MAF to the airflow may be part of the answer..... certainly Red had some success on the 2.4 when he re-orientated the MAF and that could work on the JTD too (although I haven't had any success with that measure myself).

I strongly believe the MAF is the key to whole "thing" but to be right we need folk who have had other remaps done by other tuners to post more in this thread.

I take on board Argos' point about the Red Dot remap, something I alluded to right at the start of the thread. I'm loathe to spend a couple of hundred quid on another remap to prove the point though So folk with other maps (Celtic? any others?) please do post something.....

you could do that if you can arange with peter to take a car with gsr and a map that has no errors to reddot one day, can copy the map take it in the office and have a look
try not to come on same day as rolling road day so they have more time to spend on the problem :idea:

Well, I'm a bit shocked by this

It looks like the MAF sensor has been removed from its mount (from its tube) which is going to mean the device is no longer calibrated correctly.

The tube it's inserted in has a bigger diameter (judging from the picture) which means the device will UNDER READ air flow. In other words the engine is receiving more air than the ECU thinks it is which presumably will lead to a lean mixture.

I'd guess it will also be a big issue for the turbo since it will be creating much higher boost pressure than the ECU is expecting :chin:

:yeahthat: the same happened with the 2.4 and that had to be redone because of similar happening..time people learned to leave their cars as they were meant to be and stopped naffing about with the standard parameters laid down by the manufacturer..

My mistake, just been and checked and it is vertically mounted. i was thinking about the 2nd mount that Argo has mentioned that is bolted to the airbox horizontally.

.....and also the right way around

re: JTD - GSR induction & Red-Dot remaps!

@ABZSTILO: Im not looking for this picture because I have it... Im thinking about picture inside of Induction kit... On this picture look like that MAF is about 5-10cm nearer engine...
As someone said maybe Induction kit do not produce right air circulation and MAF report wrong values to ECU...

I hope I will quick receive any response by Peter about Induction kit because without it I cant test diferents maps...

Im build about 8 Stilos with 160HP remap and 2 are produce errors... One was owner drive to local service and they are change one tube near turbo and probles has been fixed, for other we are not looking for any solution but we are build 140HP map which work ok...

Is there someone who have this Induction kit without remap? Or someone who have kit and remaped ECU without any errors?

P.S. @ABZSTILO: You can go to chip tunner who are produce your map and tell him that you have problems with your car and if he can put original map to your car... He must have saved it... When I remap any car I send original file to custumer email or copy it to USB device...
If he haven't your original file then ask him if he can read file from your car and send/copy it to you and I will look in database for original file...

Slight problem of a 900 mile round trip though.


Also with regards to the maf not reading properly because of the different dimentions of the maf housing. Isn't that one of the parameters adjusted with the new map.

See to recall rightly or wrongly that that was an issue with the 2.4 and a tweeked map sorted it out. Although I may be misremembering that bit.

Yes, maybe is only problem map but we don't know that... Im receive answer from Peter that 1.9JTD induction kit is on hold now, now Im waiting for how many time we must wait for fixed induction kit... But if this take to long I will take any other induction kit... I don't want wait to long because I will spend all money...

Might be possible I suppose :chin: but seems a hell of a lot of work to reassign operating parameters to a device which Bosch must surely have spent a vast amount researching.

Power tuning isn't supposed to be easy.

Power tuning isn't supposed to be easy.

Maybe but not much point inventing the wheel twice is there (as in duplicating work already done )

Sounds crazy mucking around with the MAF's parameters to me

Just think of the implications - every time you removed the GSR kit then you'd need a different map - as otherwise engine goes like :yuck:
