fitting saab injectors to mk4

[RTechUK]

No much appreicated now know a bit about injectors and maping for the AGU now ! 

What spec is your car and what are you planning to do? let me know and I will point you in the correct direction of doing it right, safe and cheap.

Think you did my mate Steve Tates Golf.... : Blue, AGU 1.8T GTI couple of months back down here in West Sussex? He reconmended you. Just getting it ready for it be maped at the moment with a forge RCV, and doing the oil pick up too..

Spec is 2000 GTI ,1.8T 150HP AGU

Current mods are: Air Filter and Custom / Powerflow Turbo back exhaust.


I'm aiming to have get it into the mid 200s...Been told with injectors that the 380cc are the ones to go for? What maf would I have to get?

And plan is to have it cammed and have the K04 turbo, aftermarket intercooler, 380cc injectors so wondered if it would be best to just have it maped after this?

Although I've been told that after the R-tech map just from Steve's AGU Golf with just a 007 RC DP, and decat that it felt like a different car and as quick as a 32, so wondered whether to just get it maped in the next month or two with just the dump valve upgrade, air filter and turbo back exhaust for instant power gains for the dollar as opposed to doing all the above....then getting maped and spending thousands..

so saab red injectors arent any good for AGU spec  with LCR maf?

An LCR maf wont fit an AGU.   There are campanies who will make you custom maf tubes.  The maf that fits the AGU will the the one of an old mk3 VR6.

ok cheers, and a VR6 maf will be big enough to suit the red injectors?

What about the housing from a PD 130 passat, same fitment for sensor itself?

Geting it cammed will be a waste of time and money down the pan imho.  If you going K04-023 setup then you will need 225lph fuel pump, THS FMIC, VR6 MAF,  saab red 340cc @4bar  or Genesis 380cc remap and then you looking at a max of 270bhp 280lbft

hello, I have the same question,
  because I have a VR6 maf and injectors saab red but I'm reading that the injectors to be put together with the vr6 maf are the yellow saab injectors

As long at the injectors are a close match % to the maf % then less work is needed in the map. 

The AGU has a setpoint map for relative fuel mass v Air mass (Grundanpassungskonstante) the idea is not to change this map/or change it very little. When the Grundanpassungskonstante map gets changed is offsets all the load axis on the lambda and ignition maps which mean a hell of a lot of time rescaling the whole map so the ms% load axis reading match what the car is doing.   The best way to do it is get the maf size and injector size about before mapping.  Reds with VR6 maf is not going to take too much work so setup, maybe a day of logging fuel and load to get it 100%.

It took me a week to scale a set of 630cc injecotrs on an AGU with vr6 maf.

[RTechUK]

Stock is 2.44" inner diameter good for 240cc

Vr6 maf is 2.75" inner diameter good for 310cc yellows

3" inner diameter  good for 360cc

3.25" inner diameter good for 440cc

Nick you got some part numbers for the various maf's you mentioned above, also I do have a second query.

I want the double blip on my AGU for pops, bangs and flames, I'm in kent and I've had stage 1 done by you guys, what would be the easiest way to achieve this?

Also is there an easy way to increase limiter a tad, I read I can only lower the rev limter via vag com but not increase it which makes no sense.
