I swaped from a stock Eaton to a GEN1 2.3L Whipple and installed a Return Style Fuel System during winter and a 200A Alternator with Big 3 wire upgrade.
I´m doing a remote tune with a very well known men
My tuner send me a idle tune according to my modifications. It starts normally but after ~30 sec it idles bad.
93 Octane Tune should be good, so it must be some mechanical /physical issue
Here a short idle video (at the beginning and end I manually hold the RPM to around 1k RPM)
What I have done so far:
- checked all vacuum lines, used leak detection spray around the blower --> no leaks
- Fuel Pressure is set to 40 PSI (according to gauge on fuel regulator and FRPS(read out via SCTX4))
- No fuel in vacuum lines from FRPS and vacuum line from regulator)
- Unplugged FRPS --> no change
- I pulled the spark plugs, three of them looked little wet
- filled the fuel tank with fresh 93 octane fuel (no boosters used)
It showed me 4 codes
P 0406 and 0403 --> both EGR related codes, I forgot to tell my tuner that I removed it
P2195 and P 2197 after the engine died by itself --> O2 sensors showed engine was to rich but why?
My mod list (engine wise):
- GEN1 2.3L Whipple with 3" pulley
- Return style fuel setup with ON3 Hat, 2x 320lph pumps, Fore Fuel Regulator, Dash8 feed, Dash6 return, Stock Rails, 60lbs Bosch Injectors (flow tested and cleaned before install)
- New NGK spark plugs gapped .028
- JBA Shortys, Magnaflow X-Pipe with 200 Cats, SLP Loudmouth II
- EGR Delete
- Cooling Mods (170° Reische thermostat, LFP Heat exchanger, head cooling mod)
- 200A KMJ Alternator with Big 3 Wire upgrade
- Upgraded double bearing Idlers, Roush Tensioner, Snub Idler
All the help is appreciated
