Guest DATTO Posted March 23, 2003 Share Posted March 23, 2003 ok how much is this system worth..running a 300z ecu, 300z MAF and the harness all crossfired ready to run with a 280zxt harness. he also told me if you want to run the stock 280zxt flapper door and ecu...just plug it in and it works as well. he didnt say what he'd charge for the system but i think its the same style that jim wolf does minus the bigger injectors. hes going to show me the setup tomorrow on his turbo 240z. said installs in 5 mins. only thing he said you gotta adjust is the idle because with the MAF it breathes more air, it also has the 240sx TB. what yah guys think? he said he can make more systems ready to be plugged in your turbo 240z.

bumble zee Posted March 23, 2003 Share Posted March 23, 2003 your saying a maf hooked up to a 280zxt harness??? if so, i want details!! Quote Link to comment Share on other sites More sharing options...
Guest DATTO Posted March 23, 2003 Share Posted March 23, 2003 hey bumble...YUP the 300z ecu and MAF hooked on a 280zxt harness ready to rumble! ill try to take pictures tomorrow Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted March 23, 2003 Share Posted March 23, 2003 Yes, it can be and is done. You must beware of hooking up the MAF connector backwards! The keying is defeated, and the ECU will go south on you if you connect it backwards. Also, it's NOT the same as a JWT without bigger injectors. The JWT has code inside modified to operate bigger injectors, as well as rev limits and ignition curves modified for more power. Don't fool yourself - it is a stock ECU, and it will work just like one - I know, I run one. Quote Link to comment Share on other sites More sharing options...
Guest DATTO Posted March 23, 2003 Share Posted March 23, 2003 oh yea my fren remapped the ecu to run like the JWT ones,he figured out what JWT was running and improved it a bit. JWT ecus liked high boost so he changed the deg per boost and got the same HP with 15 psi rather than 21 psi. he did this stuff at his work.

I hope I don't sound too doubtful, but the Z31 ECU doesn't sense boost, so how can you say you changed the "deg per boost"? What is that? IMHO, the only way you will get more power at a lower boost level is to upgrade the turbo or intercooler, or port the head and use a hotter cam, increasing flow and/or redline. The ECU should not be adjustable that way. If what you are saying is true, then you may have leaned out the fuel to a dangerous level, or increased the ignition timing to a (again) dangerous level. From what I've heard, the JWT stuff is tuned pretty well, and it would be hard to improve it. Quote Link to comment Share on other sites More sharing options...
bumble zee Posted March 24, 2003 Share Posted March 24, 2003 so how is this done??? how much does it cost?!?!? i have a 300zxt ecu and maf avail... this would be nice for my turbo Quote Link to comment Share on other sites More sharing options...
