heat light problem (apexi PFC) 92 type x manaual

[Eddie]

had my car now for 6 years imported from japan myself, no proof of engine rebuild, upgrades are after import and done by me.

apexi filters, exhaust, wgt decat, trust fmic, uprated rad, fpr, apexi ecu with pfc.

my problem is

my heat light comes on after i have got the car onto boost, then the heat light stays on, i can still boost and have on the odd occasion booted it like mad and all seems fine.
My OMP is highlighted on the pfc when ever this happens and the heat light stays on for the remainder of the drive.

2 questions, should i just remove the omp and premix?

or

replace omp and see if problem is solved?


I got further mods planned soon, hks down pipe, new plenum with extra injectors, boost controller, new zaust and was hoping for input as to which way to go, i will do all the jobs at once then get it mapped again.

hoping to run 0.9 boost for the mapping.


thanks in advance for any input.

regards
