17 Civic SI US

[Repoejr]

I just purchased my flash pro and flashed the pre loaded +6, my car is stock.

First gear drops on its face at just about any rpm with wot, all other gears seem to drop on their face at 5500 rpm.

Anyone else have this issue or can help?

Can you post your datalog showing the problem?

[Repoejr]

This was 1,2,3 and into 4th and it fell on its face and all system lights came on. What normally happens is I take it up to 6k then shift and it bogs to about 4k but no lights come on. This is the second time all the system lights come on.

Pre loaded 9+ psi non fts tune.

looks like the ecu is seeing overboost and throwing it into limp mode. its peaking at 25ish psi

We normally see around 26 psi from the +9psi calibration, so the total boost of 25 psi is about right.
What I think is happening is that the ECU sees the BP is much higher than the BP.CMD when you shift (at 15 seconds in the datalog) and generates the error.
What you can do is to increase the boost limit tables TC Max Boost (IAT) and TC Max Boost (PC) by 0.1 bar at a time and check the error goes away.

run this at your own risk

I added .1 bar to Max Boost (IAT) and TC Max Boost (PA)

You may need to go up more than 0.1 bar, but the 0.1 increase in the calibration would be a good start.
