Summary of change:
Audi RS2 Avant Engine: 2.2l Mahle pistons scat rods GT3071R turbo (0.63AR) OEM inlet/exhaust manifold custom intercooler/downpipe water-meth injection 70mm catback with x2 200cpi BN pipes catalysts Stock cyl head with stock ADU cams Spec 3+ clutch kit for dual mass flywheel running VEMS with megatune 1.1.27 for 9 months now!!! Results with Perfomance box: around 410hp with 1.85bar overb. and 1.7-1.8bar steady to redline on 4th gear pulls. Max torgue reached: 600Nm, but keep it around 580Nm now. ------- Next year: Holset super HX40 with 0.70AR reverse inlet manifold SQ exhaust manifold New downpipe ------- Issues: Idle control finally solved but always small modifications for fine tuning. I use diode for ISV valve and a combination of ignition based idle and IAC intervention to keep idle steady and allow minimal play when fan kicks in or A/C is working. So far im very pleased with the results Version 1.1.27 is very stable but would like to switch to 1.1.62 with vemstune.I managed to connect the laptop to ECU on 1.1.27 with vemstune. I will wait for the 1.1.63 version which has the boost control bug fixed, as i use vemstune to control boost with an industrial solenoid valve. Very accurate boost control!!! ------- 15/11/2009 Removing the MAF from the airfilter caused some overboost cut outs for some reason and i had to adjust the boost control figures. Noticed that the offset feature will not accept value 15 on 1.1.27. It will only go from 16 to 14, although when i did save and burn to ECU the value 15, i did notice a change in the highest boost reached. Vasilis
