Hi guys, like tittle say, when press the gas the ign. Advance in the datalog went to 6-9* and the engine bogs and not want rev. then slowly begin to rev. and the timing to increase. Is this this normal?

Also, The TPS log number need to increase immediately or a few and jump to 2-3 (this is pressing and let the pedal).

By the way, This is the second distributor and this is OEM TD-87U take of a perfect running B18C5.

Any info needed LMK.

Thanks

 

What tuning platform is this?
Are you running a basemap or is this calibration tuned?
Can you post the datalog file?

 

Thanks, for the response.

1-crome
2- Yes, car is tuned and this start suddenly.
3- I will try, never try to make a datalog file in my notebook and post it.

 

When you press the throttle does the datalog show a TPS increase? Did you calibrate the TPS sensor with Crome?
Which MAP sensor are you using with Crome?

 

MAP is Omni 3bar

TPS no, Never calibrated it in crome. And yes, I note a slight difference when press the gas till the tps log increase

 

Muckman, Datalog shows -28.0 MAP reading at idle, is this number fine or too low. The boost gauge shows 26vac. and the data login is in the -21.2 column in the table.

 

This for now maybe help.

if you look at your ignition maps, yes, this is normal.

I'm concerned that you're boosting a high compression engine on free software with no experience. Even with my experience and good software this is a challenge.

Anyway, if it started randomly after it was tuned, you need to check your compression. Typically a boosted C5 will end up with cracked ring lands or a blown head gasket if it doesn't bend the rods first.
