Any thoughs on a plug-and-play tuning module for the Z Nismo?

ECUTEK - i‘m pretty sure re-flashing the ecu back to stock will clear the boost history. Would be a good question for race box to verify.

This is where rapport and due-diligence comes into play. If you need convincing, simply drive to Nissan and ask a service manager in person. Your direct questioning in person will be met with transparency and appreciation for taking the time to show up and ask 99% of the time, and no, they aren’t going to ask what you drive or who you are to answer that question. @Racebox would be great to ask but only because of their reputation, despite offering tunes, they would not evade or be misleading about it.

Lastly, if you search the internet in a way that will yield unbiased (subconsciously or not) results, it will spew definitive results. I.E.


“- ECU Data Logging: Modern ECUs, including those in the GT-R, store a lot of data about how the car has been driven and any changes that have been made to the system. This data includes information about peak boost pressure, which can indicate if the car has been run with increased boost levels beyond the factory setting.

- Flash Counters: Some tuners might claim that flashing the ECU back to stock will erase any trace of tuning. However, the ECU keeps track of the number of times it has been flashed. This "flash counter" can show that the ECU has been rewritten, even if the current tune is the stock one.

- Nissan Diagnostic Tools: Nissan has sophisticated diagnostic tools that can delve deep into the ECU's data and logs. These tools can potentially detect signs of tuning, even if the tune has been removed and the flash counter reset (though resetting the counter might be seen as further tampering).”

Don’t forget that non carb approved ecu flash will not pass California smog.

if you re-flash back to stock, will it pass the carb approval? Z1 offers a carb legal ecutek tune.

Of course the ecu stores history and nissan can dig into the ecu’s history. nothing new/ modern - that has been the for decades.

question is what variables are cleared when reflashing the ECUTEK tune back to stock? there is not a lot of ecutek tuning info on the net. An ecutek master tuner can better answer the question. a stealership would be the last place i would look for service out side of warranty and certainly not for tuning info.

What’s the probability a service tech will dig into the ecu for tampering answer: it depends….

for normal service / repairs a service tech is not going to call in a master ecu tech to check for tampering. But if they do and see the ecu has stock program & current rev, then he will be less concerned with flags & the flash counters.

We have a member that washed his engine had a sensor failure and was having boost spikes of 20+psi when shifting. the early autos were reflashed for tranny issues.

there risk of warranty coverage with any form of tuning - if you roll up with a blown engine its a safe bet that you are screwed.

I don’t understand how a dealer can’t see that stock boost was exceeded.

They certainly can - question is what was the cause - there are lots of possibilities

the question i have - can tuning software like ecutek clear the boost history?
