LS3 conversion 2000 C5 Corvette

[KK Autoteknik]

Hi

I have a Corvette C5 LS1 345ps.
I have swaped the engine for a 485ps. LS3 engine, mounted with trigger setup from Lingenfelter
( Lingenfelter TRG-002 58x-24x crank trigger conversion module )
and Lingenfelter high flow 90mm. throttlebody

I am getting error code P 1514 "throttle"

Is there anybody can help with a base map for this setup.

all the best karsten kjeldsen

Thanks.

P1514 is normally a Throttle blade position vs desired position mismatch. Check Throttle blade color.....should be silver, if gold, then you usually need an earlier TB (LS2 stock version). Gold blade opens in the opposite direction and throw TAC module off. Not familiar with the LPE TB, give them a call and see if compatible with LS1 PCM. Also will have to rescale the IAT.

Could you specify what exactly is this TB? Does it fit directly into the LS3 intake manifold without any adapters?

2006 GTO sliverblade 90mm. fits the LS3 intake.

Are you answering which throttle blade the OP is using or reiterating the above?

I just went back through some of my open threads and after rereading this one, realize I read it wrong the first time.....The 1514 is a mismatch of airflow vs TPS, Baro etc...there is a table in the Gen III Eng Diagnostics>Airflow where you can adjust these values.

What I do is set up a graph/histogram using the editor table axis and log MAF airflow. Verify the values at the specific breakpoints and add say 10% to the logged data and update the editor table.

Sorry for the confusion.....
