why is it with relative ease you can wack up the timing , fiddle with WUR & get 170BHP+ from a KR, but you cant mimic this electronicaly on a ABF?
I would of thought with an ABF and bit of mapping this would be easy..............................

you can fettel the ABF most of the chips are crappy and just offset maps. i put quite a lot of effort into the chip i have in my ecu. afr's are bang on where i think they should be and the advance is plentyfull and agressive. dosent like 95 fuel as it trys to ping sometimes running on that. no idea what its makeing i chouldn't be arsed to dyno it but notcably up on what it ran before

You can. Just use the same rollers as the standard KR + WUR mod shows 170+ and you'll have more with a re-mapped ABF.
Or, try seeing how many KRs make 160, never mind 170+ on dynos where ABFs make 165-170. I've not seen any.
You don't get 40 BHP out of a KR without head and cams...same with an ABF...it's just that the injection on a KR allows you to run wilder cams than the standard ABF ECU does...so in that case, maybe you get a few BHP more.
But a standard 1.8 KR making 170+ with only timing and WUR mods...not that I've ever seen. Certainly not on the same day as I've run my ABF.

i recon a stock ABF motor , running open TB ( save any induction kit or airbox arguments ) and a decent 4-1 manifold and a bit of fetteling and timed up cock on chould pull 180

Not a hope in hell.
Not genuine BHP.
I've tried dynoing with no filter/airbox...and it doesn't give you anything over a decent filter/Airbox set up...the TB is the restriction, not the filter (assuming the filter is clean etc).
A 4 branch manifold has never been proven to add anything substantial either...maybe up to 5 BHP on an already tuned engine, but for one making up to 190-200 BHP, standard seems fine.
Swinging the cams may change the power band about a bit...but you aren't going to find 30BHP...you'll be lucky to get that out of headwork/cams/re-mapping.
Phonebook figures may be easy to fake...but in reality, you don't go getting 30-40 BHP out of ANY VW 16v engine with a few basic tweeks. It just doesn't happen.

I love this thread simply because in 1 foul swoop you have proved 90% of people wrong about the sh!t they talk with regards 170 brake blah blah.. i do keep an eye on it to see how your getting on.. This is why i love Cgti.. because of the knowledge base out there.. i have nando currently making me up charger brackets for my eaton.. hoping it will be fairly nippy when done..

minor fetteling :- de bumping the TB and tidying round gaskets but nothing involveing head off. to be fair you have done more reserch into it than i chould be arsed to do. mines jumped towards the ITB route whitch i'll play with for a bit but some form of boost is calling again.
we both have dyno plots, there from diffrent dynos tho. i have dyno plots showing 170 up on this forum from what i would think is an unbiased rolling road as they din't do any work on it. but all roller are diffrent end off. thats one of the reasons i plan to get my own at some point, they arn't exactly that expensive for what they can do for you.
180 was based on what i have printouts of it doing and the form it was in at that point. any whats this about haveign to send off for remaping and stuff. digi 3 isn't exactly complicated, switch noggin on and do it yourself all you need is a computer some cracked software and eeprom burner a bit like this that you can buy off ebay for naff all

of course takeig the chip in and old gets a bit old after about an hours so built an emulator for the 27c256 chip so i chould do live mapping off the laptop without haveing to take anything apart. it is also possible to use digi 3.2 with long duration cams, just because it has a map sensor dosent mean it has to use it, you can tell it to go off TPS / RPM if you can be arsed but that needs a bit more kit and more thinking

Hi guys,
I have modded an ABF into a MK2 with the org set up- digifant 2 injection system.So far all I can say is that I am happy and its relaible unlike the issues you get with a MK3 system that I am having with my other MK3 ABF.Also I find the digi 2 is more respnsive than the simos siemens system
The car currently can beat a KR K -jet injection system which has a 9A engine.I havent dynoed yet.But it will be interesting to see how many ponnies are lurking.
And yes I am still sorting out the jerk ssue when the engine rev up to 2800 rpms -4000 rpms.Exhaust emmisions are nasty and no power.Any ideas?I tried to check and look at the wiring behing the manifold.Still the same issue.(MK3) that is.
Thank you for your kind assistance.
Regards
