    GTX 185 to a gtx limited 215 WHT TO DOO what ecu

    i have a 2003 gtx 185 just did a motor build with a 2005 rxp motor now the fun part. What ecu should i put in place of the stock 7600rpm to get my higher revs. i have the rxp charger with the 16 tooth gear and the matching crank gear, also the rxp intake/intercooler. I have already swapped out the fpr to the rxp regulator on top of the tank so, i have the correct fuel pressure. What ecu what else will i run into in this swap the exhaust is getting changed as well

    you need the rxp ecu 04-05 and most likely the knock sensor update sounds like you have everything else right. your going to love the performance gain. your going to need a bigger prop as well
