Nistune Over Impul ?

[99RS4]

Hey guys brand new to the Stagea and Nissan and Boosted world lol, but I have a question hopefully someone can shed some light on. I recently purchased a 1999 Stagea RS4 S Manual. The guy I got it from said it had an IMPUL remapped ECU when it came over from Japan. The question is can I get it done with NisTune over the top or do I need a whole new ECU ? Any help greatly appreciated and Ill be sure to post some pics of the new toy up soon as I get some :-D

I expect that you will be able to install a Nistune chip in the ECU thereby losing the Impul tune. Anyone familiar with installing Nistune chips should be able to tell by looking inside your ecu.

Sounds right. Email Matt at nistune for a definitive answer.

How much is a replacement stock ecu anyway? If you are planning a tune it's the least of your costs.
