Newby tuner with 84 Vette XFI l83 engine (was 205 HP) against a th400. Original block and heads.
Using 5235206(61pph) injectors plumbed in parallel with external FPR and original TBs.
Old FPR and accumulator blocked with plates.
New cam is supposed to be a little hotter (asked for RV cam).
No EGR or CATs yet but expect to add later.
Cast iron exhaust manifold with 2.5 in. collector reducing to 2.25 in. pipes with X style x-over
Using tunerproRT v5 and 27FS512 chips and AKAH starting bin.
Need to know where to start timing. Have to advance over 45 deg just to get it to start.
Can,t keep it running long enough to get a timing light on it.
Runs way too rich, really rough and won't stay running.
How do you disable CL?
What BPW should I start with? Was 135 but set at 118 at present. FP is down to 9psi and still too rich.
Any XFI tuners want to jump in?
Don't force it, get a bigger hammer!
