1995 GTI VR6 - N/A - Schrick 268's, Race Shop cyl head, ported manifolds, Mk4 gasket, 2.5" exhaust, all the bolt ons and little stuff. Dynoed 198whp with 262 cams on stock ECU.

MSV3.57
MS1 - MSnS-Extra 029y4
Tuned with TunerStudio!

Glen/Error Daughter Board:
Modified output circuit for tach by replacing diode with 4.7k resistor - to stock tach
Launch control
Table switching
2nd MAP circuit used for MAF conditioning
Output circuit to stock CEL on until 900rpm, off until 6500rpm (shift light)
Output circuit for shift light
Fan output

Stock 19lb/hr injectors @ 4bar (22lb for req_fuel)
Stock coilpack
Stock crank sensor
Open element 1.8T air temp sensor
Stock blue coolant temp sensor
MAF retained and wired in (haven't checked if it's working yet)
OBD2 throttle body
OBD1 idle valve
Innovate LC1

Mods/Setup:

VrOut Jumper (red VW sensor to VR+, green to VR-) this is backward of all the V3's I've done but could not get sync at all rpm the other way.
Jumpered LED Pad locations to SPR1-3 direct to stock coilpack

Just a rough tune to head to the dyno with. I built the harness PnP style to be able to back to back test it vs a GIAC chipped stock ECU. Back to backs tomorrow.

More details to follow. I finally got this running after working on everything for quite a while! Hard to get time to do it between everyone else's projects!

Switched to HR10g this morning and did some tuning. Fixed my req_fuel as well I have no idea how the calculator came up with 10.3 last time. I scaled the VE table by .72 when I started tuning the HR code.

Got about an hour of tuning in before doing a full throttle pull and hit a bump at about 7.8k.. did the clutch in. Whoops! No dyno results, unfortunately.

Worked out decently, I'll attach it once the laptop is charged up.

Next up after the repair, switch to HR11 and try tuning with the MAF.

Latest msq, still on HR10g, dyno tuned at full load. As good as it's going to get before I hit the track. Made an average of 4whp over the stock ECU with a GIAC chip which is pretty much the standard all go by.

Here's the graph vs a GIAC chip (same day, same dyno)

i'm in the prosses of building a ms1 v3 board for a stock coilpacked vr6...
could you possibly post more info and diagram on your modification for triguering?
help would be apriciated!
thanks

I used a 3.57 so I just went from the LED pad locations to the spare pins. For a V3 you'd need this circuit:

Use a 1k instead of 705R, and do that for each LED.
