I am curious if anyone has put a j35 swap in there accord without doing any tune and using stock ecu. If you have did you run across any problems? Does it run lean? I have an 06 odyssey motor I am going to be dropping in but I have been waiting for funds to buy hondata before doing this. Would it be safe to drop it in and drive it until then? The engines are almost identical. They use a lot of the same parts and even the same injectors. I do have an 07 TLS ecu that I could use instead of the stock ecu. Using this would it cause more problems without using Hondata? Just trying to get some input.
