I've been saving up the last few months and I bit the bullet and got the ECU from KDMGuy at his site

www.kdmstuff.com or from his main site www.seoulfulracing.com

REVIEW:

Initial impressions without the dyno is that the car felt faster, smoother and more responsive. The revs went up faster, and the car felt stronger.
Overall I was pleased with the results. However, for the price, I didn't think it's worth it.

Impressions after my dyno and two days of driving:
DEFINITELY NOT WORTH THE MONEY. **The car was dynoed with a full tank of 94 octane gas**
Although the car feels stronger and smoother than before, I discovered that there is a flaw, Everytime you start the car you have to reset your ecu to get the 7500 rpm promised. NOt that I drive each gear to 7500rpm. Otherwise you be limited to 5400 rpm, seen on the Dyno sheet.

1st and 2nd pull shows engine cutting off at 5400 rpm and the 3rd was after an ecu reset and 7500rpm was hit. When I drove home after the 3rd run, the car was again cutting off at 5400rpm, until I reset it then it beyond it, so it's a pain having to reset you ecu before each start if you want to get a high RPM range.

I will dyno again in the fall to see if long run use will improve these numbers.

congrats!

I'm not sure how much you paid, but for that little performance increase, I wouldnt bother.

 

[FordFasteRR]

Wow !

Awesome # 's for just an ecu swap !!

I am a bit concerned with the glitch you discovered.... lets hop you can sort that out.

I hope your being sarcastic about the awesome numbers....

I have mods on my car too as listed on my sig.

but I also have:

SRI
JSpeed Pulleys, both accessory and underdrive
and REsonator back exhaust.

cypher dialed in at 141 with his car...well when he had an a$$ load of work done to it. search for it

You didnt do too bad. You dont have a multitude of things that jim had. Cam gear, quality headers, ported im and bbtb, and youd be near or at Jims numbers.

Unless Im reading this wrong, you say a 5hp/5tq from changing the ecu.

Just about that, but that also includes the Jspeed underdrive.

 

[ArunSenior04]

OOOOOO. Gotcha.

i had UDP

got a reply back from KdmGuy about my results, he say's to remove the speed sensor? Can someone let me know where that is and if it's safe to do this?

 

[SuperGLS]

That's interesting. Please keep us updated. I'm afraid I can't help out on the speed sensor thing. Doesn't seem like a safe thing to do though.

 

[ry4nolson]

and it doesn't make sense. you need to know how fast you're going.

 

[4mynikka]

and it doesn't make sense. you need to know how fast you're going.

Apparently the speed sensor is sending a signal that the ECU is not reading causing it to just drop.... we'll see what happens, I'll try it and go from there.

 

[g35doc]

What are your before numbers? It's hard to read them.

 

[ilanpro]

if you remove the speed sensor you will redline at 5.5K RPMs

 

[4mynikka]

Well, Good news, KDMGuy will be sending me another ECU.... to fix this problem.

I'm going to dyno it again so that I can give a feedback based on a properly functioning product

What are your before numbers? It's hard to read them.

127 whp and 129 tq

if you remove the speed sensor you will redline at 5.5K RPMs

And this was verified, I was still hitting the 5500rpm.

 

[Cypher]

sweet. can't wait to see what happens with the new ECU

 

[yamaha]

How much did you pay for the ECU swap?

 

[slow 2K2GT]

well at least he is willing to send you a replacement ECU to fix the little problem, I would imagine the reflashed unit wasnt cheap. Seems like good customer service from Korea, good luck!
