Thread: built in 2step?

I think there its no 2 step for B14's but your problem its def. a limp mode problem.... When you get the check engine and fans on all the time there is limp mode...

ya and check engine wasnt on before the swap.. so im sure something has got to be up. i upgraded flywheel and clutch also so hopefully i didnt put the wrong one in there which is causing the cel on.

kaottekxe, i have chips from alfredo too..he did the 2 step on mine and worked great...

im sending my chips to squirlz to reburn them ,reaise tthe 2 step and remove the ghey 8k limiter.

oh really? well i could be having some sort of different issue. i wont know untill i try the other ecu on it.

Your radiator fans coming on as soon as you turn the key on is an instant give away that there is a problem with the ECU or the chips. Hopefully reburning the chips will fix the issue.

ya i thought that was wierd, its both fans to not just one.

By two-step are you meaning launch control?

Check the direction of the chips, its the easiest thing to get wrong, and easy to fix. They have a notch that should be same direction as the notch in the socket the chip goes into.

ok i will have to do that. my lil bro just swappd his ecu into it and the car runs fine so there has got to be something wrong with this alfsentra ecu. ill check on the chip direction when i crack it open.

how do i know if these chips are on backwards.

Look at the outline?
