[How is the "staging" of engines categorised?]

It varies as there's no official definitions: https://www.torquecars.com/tuning/tuning-stages.php

Makes sense, thanks. Though there might have been a Celica S3GTE guide. 

[How is the "staging" of engines categorised?]

Hi all.

 

I'm interested to learn how we categorise the staging of engines both mechanically and electronically. Is there a guideline as to what needs to be down to achieve Stage 1, Stage 2 etc?

 

Thanks,

[Any ideas what this is?]

I think i'm going to swap out the Fuel Regulator before i invest in remaps. It seems to run rich on idle (the smell is quite nauseating) but fine when in motion. Does that ring true with anyone?

It says boost map analyser, so I suspect it's probably a boost controller or add on for one. I very much doubt it would affect a link ECU.

 

The big question is whether the link is running closed loop, and whether that is from wideband or standard O2 sensor. If it is closed loop then the sensor is probably duff. If not, then it may need a tweak.

 

If you can post up all the figures it will give more clue as to what is wrong. It may not be mixture out at all but a duff cat, exhaust air leak or some other problem.

 

Is it a G3 or G4 link ? The G3 is very difficult to get the idle right.

 

The good news for link is that the tuning software is free to download and easy to use if you know what you're doing. The latter part is the downside.

 

The Co2 zipped up to 9.59 in a flash and all other readings were on the up - the MOT chap couldn't get the probe out quick enough, something about tripping the machine out and having to call an engineer.

Hi,

 

I'm close to pulling my hair out following my MOT Failure due to excessive emissions. Seems i may need a remap and/or a replacement fuel regulator. 

 

However in the meantime the attached photos show a Blitz unit that was supplied with the car. I have no idea what it is or where it goes but i'm hoping that it's a plug in fix that reverts the map to a MOT friendly setting. Can anyone advise what this black box is used for and if this could be the case? I'm currently running a Link ECU with MOT emission at 8.2+ 

 

Thanks in advance

[ST205 GT4 Shock and Spring Replacement]

Thanks for all the pointers here guys. Much appreciated. 

Over the weekend my steering pump started to whine so I'm going to doing a fluid replacement before a pump replacement, before a shock and spring replacement :-)

[ST205 GT4 Shock and Spring Replacement]

Thanks Chris, a great help. 

I've looked on TCB and find the genuine shocks more expensive than the KYB, which is to be expected, however reading your message i concluded the KYB was a "mild upgrade" and as such, expected a higher price than the originals. There isn't any "shock" rating shown in their description so i'll drop them a mail.

 

One other thing. I notice they have;

 Set of Tein S-Tech Lowering Springs (approx 37mm lowering) - Spring Rates FR 241 lb, RR 207 lb.

37mm seems like a lot to drop the car (see image in original post) so perhaps i should stick to a set of originals?

 

Thanks again.

[ST205 GT4 Shock and Spring Replacement]

Hello!,

 

My 95 GT4 is due it's MOT in a few weeks. A preview of the shocks revealed missing bump stops, leaks and missing dust gators. 

At the moment the car is my daily :-) so i dont have the luxury of a full or even partial running gear revamp so my question is do i use the potential / obvious MOT failure to upgrade the shocks and springs or will standard supply suffice? 

In addition, i notice that some of the brake back plates have eroded or are missing. Not sure if this is a failure or not but it makes a right mess of my Enkie's. Can these be sourced easily?

Finally, if i could get away with doing one side at a time (in a day) so i can keep the car mobile more than not, are there any other suggestions as to what i should be doing while undertaking the spring and shock work?

 

Thanks in advance.
