Hey guys, am i still good to pick my car up tomorrow?
Was hoping to find out by today as it's a good 3 hour drive for me so i'll be leaving early!

Hello

Yes fine to come and collect the car mate.

Shame AGU to 7.5 conversion is not straight forward, but some of the European tuners seem to do kits to make it as smooth as possible to change to the 7.5

Do provide more information!  But the thought of additional sensors to install etc is only more money. lol

Bloody hell....that IS smooth!
 

Thats what the me7.5 ecu is like with the Forge actuators, using the mapping to its best to get the load smooth...  Just shame the AGU ecu aint as dynamic.

Its amazing.  Probably one of the best graphs ive seen! 

Got my 3" maf today, save some pennies up and booked back in to see what we can do

On my car took around me around 12months to write the base N75 map, boost PID maps, and the linearization map to work this good with the Forge actuator with the yellow spring,  The normal N75 map will cause a huge spike and midrange dip where the PID over compensate the boost control

takes a while.  With any luck, we will be able to get the current mid range power a bit more and hold a bit longer towards the redline.  With the extra torque low down aswell will be nice.  Cars a animal between 3000 and 5000 rpm at the minute.  Cant imagine how good it will be with a extra 15-20 bhp mid range to play with and a nice peak at redline/high revs

Your next step is 2.75" maf calibra yellows at 3bar and EBC or MBC, then I will write the part load fuel map for the yellows in to your current map via you posting me your ecu or me sending a my lone ecu,  then you borrow a wideband lambda logger and do some logging and report back, it make take a few map tweaks to get it right, but by using two ecus you not going to be without a car.

Not easier just to pop down for a day/session and let you work on it in the garage? Lol

If you dont mind the trip I will be willing to set it up and finish it off on the dyno for you.  When you fitting it then?

Just a note!

 Once the 2.75" ID maf and injectors get fitted the map will be SCALED DOWN by the MAF increase %  which means all the ignition map will be offset my around +5 /+7deg and the open loop load will be around 28% greater which means more boost demand.
 As the car will be running a little richer, the extra timing should not be any cause for major pull (just do some logs to check)  As for the the extra load/boost demand I am 99.9% sure on your car the yellow spring in the forge actuator should cap the peak to around 21-22psi but will hold it a lot stronger in the mid range.  If the extra load demand cause a spike then you will need to run an MBC line line with the n75 to just cap the peak boost unti you get the car to me for mapping.

[Chris.]

Can fit it whenever.  Not the hardest of things to do stocking a set of injectors in and a maf to make fit.

So with the 2.75" ID maf and calibra yellows on at 3 bar won't need a different map on it until I can get to you for tweaks or get my ecu to you?   It will just run a bit rich?

You need to log and check the timing and boost... but from experience of the AGU ecu I am 99.9% sure it will be fine once fitted the yellow/2.75" just fine tuning nee on a few fuel maps and some of the load axis on the timing maps at a leter date when your ready.

[Chris.]

Spot on!  Ill chuck them in today and do a few logs of the timing (which block is needed for that?)  And i presume its a 3rd gear full load pull from start to redline?  Which boost blocks need logging?

PS - mate was talking to a guy in a garage and the yellow tops aint all what they are cracked up to be and can sometimes cause misfires.  He said they werent the best in the vauxhall lumps either.

Now on my way to you guys. See you in about two and a half hours!
