I dynoed my car with my JWT ECU today. The result 7 hp.......loss.

The
only thing I can think of was the ECU had a sticker that said S3/S4 cam
program, but I have stock cams. I had the timing at 15 deg, ran it twice,
advanced it to 17 deg, no change. The car ran a little lean too. The runs
before this was a 141hp run, now my best was a 133hp with 15 deg and 134hp
with 17 deg. How much timing does the cam program take off? I didn't order
the ECU with the cam program, and my receipt from APEX doesn't mention it
either. Please help. Here are the runs:

the first 2 are 15deg and the second 2 are 17deg.

Hmmm I bet it would take off 7hp to guess

Well I would just call them up and see what they say. Cause I doubt the wrong cam program does much good... Probaly just a screw up, or you could since you have the ECU order the cams

LOL while you are in there.......

thats what I was going to say. Now you HAVE to get the cams!

if you don't want the ecu, I will trade you for my stock 98. I am looking for an older one anyway. (95-97 mt)

Dude..that sucks.

But here's my advice. Wait another couple weeks to dyno it. I bet you'll see some decent hp GAINS. Try it.

Do you have a stock ecu handy that you could put back in and dyno? Any 95-97 200SX SE-R going to be at the dyno day that you could borrow?

 

[NoVTECSER]

I still have the OE ECU so I'm going to try again tonight. Its not like I swapped the ECUs and dynoed the same day. I put the JWT in friday, and ran it last night. I bought a ECU from a junk yard for $75, and sent that one in as my core.

 

[Storm88000]

Seriously, wait about two weeks.

do you want to sell your oe one? I need a core, and am having a hard time finding one.

 

[NoVTECSER]

Nope, sorry Brian, I want to keep my OE one. I'll trade you your S3 cams for it though

 

[brian]

you don't have to tease me

hey noVTECSER, I thought we have a "learning" computer in our cars? I have read somewhere when you do mods, or other major changes to unplug the positive battery terminal for like 2 hours. This supposedly resets the computer memory for ignition timing, fuel curves, etc. Then it starts to relearn under the new circumstances when the battery is reconnected. Don't know if this is true, but when I bought my JWT computer for my 92 se-r and then later for my 96 se-r, this is what I did, seems to work though. Good luck.
