Ray Hall retired? ahahahhaah

Just ordered and received a Vi-pec ecu from him yesterday. :P

Out of curiosity, where did you get this information from? Let me guess you googled and went to boostcrusing.com.

LOL!!!

If going aftermarket I think the Vipec is the way to go if you want a lot of good features for the money. I have only been reading through the manual for the Vipec, but from what I've seen the closed loop fueling is really good, you can set up delays against RPM to account for the time the exhaust gas reaches the sensor.

The closed loop boost control looks pretty cool also, you can stage it so you run 100% WGDC up to say 80% of your target, then you switch to PD control until you get to say 95% of your target and then from there use PI control. I have been trying to replicate something like this in the stock ECU, but I don't have the PD stage, just PI and it means I have to set the turbo dynamics a bit more conservatively to prevent spiking on gear changes.

It's just a pity the man behind Vipec Ray Hall has retired. But it looks like he has set up a good team to take his place.

OK he is semi-retired. I got this information from the Vipec forum here.

ECUTek and verso, practically the same, one licensed, one not. should check out the new ECUTek race rom, more things unlocked for 06-on

This... thats why I suggested what i did, 99-00 AFM's are poo. I know a guy with a PFC, his AFM started playing up. When he got it replaced, the car had had to be tuned again just to compensate.

So thats the AFM fault, not the ECU's.

BALISTC · #76 20-07-2011, 08:11 AM

MoTeC or GTFO

Kato · #77 20-07-2011, 08:18 AM

So considering this thread is for GC8...

PowerFC - $1000-$1500
Vipec - $2000-2500
ECUtek - $2000 (assuming similar cost to a stage 3 for GD)
Autronics - $?
Motec - $? (PNP board for a 99/00 is $2800ish + features + tuning time)

All are far superior to the stock ecu.

All information talking about GD/GR ECU's in here is just a waste of time as it is a completely different kettle of fish.

If I had a 99, it would have a motec pnp in there right now.

Thanks for that.

Industry getting a bit lonely with a lot of good guys leaving the last few years and least we need now is for Ray to leave entirely.

So run a z32 maf and lose subarus hamstrung maf choice for 99-00.

Or run a Vipec or a Link or a Autronic and run whatever size intake you want, rotated mount turbo, etc, etc. the mind boggles.
I did not say that the PFC was dumb, inept, or basic, just old. Time marches on, and technology does too.

IMO, we should be pushing forward at every opportunity, I heard about this ECUtek raceROM thing. People have been OS tuning it in the US for at least 2 years. It just based on a Group N ROM from Subaru.
Thats how far behind we are.
