ECU for a KLZE....

[2.5mx3]

What's up everyone!<P>Hey, this is my first post on this board -- I've been a long-time member of the e-groups list. <P>Anyway, I've just swapped a KLZE into my MX, and I need suggestions on what ECU upgrade I should perform.<P>Right now I'm running the 1.8L ECU, and my idle is quite erratic. Also, I feel I could gain a little more power from a properly-tuned chip.<P>I guess my options are to either get a 2.5L chip, have Corksport tune my existing chip for the ZE, or have a company like SuperChips burn me a custom chip. The KLZE-tuned chip from Corksport would set me back $400...<P>Also, what kind of power increases can I expect from having the right ECU/chip? Is is possible that my current ECU is limiting the power from the KLZE?<P>Thanks for any sugggestions!<P>------------------<BR>Hank<BR>'92 GSR<BR>2.5L KL-ZE

Thanks man! Yeah, I figured CS just sent the ECU's away somewhere... just didn't know where. <P>I don't use ICQ at work anymore, because of the firewall , but you should be able to catch me at home. I can't recall my # off hand, but I'll get it to you sometime.<P>Later!<P><BR> <BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by David Coleman:<BR><B> Corksport just sends their chips to E.L.

dude dont do it<P>no chip will give you more than 5 HP unless you have a ZE VAF sensor.<P>if you dont have a ZE vaf get a 2.5 KL03 VAF and a 2.5 94 ECM.<P>I can send you a chip that has been dyno tested and it got 5hp at the wheels accross the entire RPM band.<BR>You just need to de solder the old one and solder a 28 pin socket. I will even send you a socket.<P>I will also test this chip out on the 29th at the drag way.<P>Dont spend hundreds of dollars on generic chips - just not worth it.<P>Steve<P>------------------<BR>All motor 176WHP Mx3 - Dyno test coming in April

Steve I have the KL03 does this chip work? 5whp would be great <P>------------------<BR>Clear White 2.5L GSR

Ahh, don't worry. I pretty much made the decision not to go with those companies. <BR>But I wonder if I could source a ZE VAF... Maybe the place I got my engine from would be able to get it. He said he could pretty much get any J-Spec part.<BR>I think I'll call my man up tomorrow. <P>I've already got a 2.5 KL03 VAF, remember? It's from a '94 Probe GT. <P>Steve, it would be great if you could send me a chip. I'd emailed you about that a couple days ago. I really appreciate the offer. I'll send you my shipping address, and any other info you might need via your email. <P>I'll probably also end up trying to find a '94 2.5 ECU so I can swap in and out, for testing when I hit the track.<P>Thanks again Steve. <P><BR> <BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by cybertekguy:<BR><B>dude dont do it<P>no chip will give you more than 5 HP unless you have a ZE VAF sensor.<P>if you dont have a ZE vaf get a 2.5 KL03 VAF and a 2.5 94 ECM.<P>I can send you a chip that has been dyno tested and it got 5hp at the wheels accross the entire RPM band.<BR>You just need to de solder the old one and solder a 28 pin socket.

Hey Hank I will email you off the list on Monday when I get back to my office<P>hey White Fish - yes this chip will work in your ECM<P>you have to de solder your old eprom and solder in a anew socket. Once thats done you can swap chips in a few minutes time.<P>The EPROMS are not in production yet but I have a few more to give away for around 25 dollars.<P>Steve<P>------------------<BR>All motor 176WHP Mx3 - Dyno test coming in April

wow 25 bucks cheapest 5hp I will ever buy<BR>Sign me up<P>If I put 2 chips in will I get 10hp hehe<P>------------------<BR>Clear White 2.5L GSR

Let me clear this up. If you get the Corksport/E.L. Prototypes ECU to ZE specs it will give you about 8 wheel horse power. I've seen dyno proof of this. 3 different ECU's were used to get that data (back to back). And 8whp was the conclusion. I posted this data on Probetalk once to end an argument. The dyno slips have been taken of the net since so I can't do it again.<P>More info on that ECU upgrade-<BR>Corksport obtained an actual computer from a KL_ZE powered car. Sent it to E.L. and had them make a program from that. I have figured it out mathmatically that buying that upgrade is actually a better $/hp ratio than buying the engine itself! Well, that was for a Probe anyway. You guys with MX-3's are gaining ALOT more with the ZE engine than a Probe.<P>------------------<BR>Mazda Powered 93SonicProbeGT<BR>AIM:Benkrys<p>[This message has been edited by Sonic (edited July 16, 2001).]

Mr Sonic.<P>I just put my hands on a Jspec VAF sensor so I can finaly test my ZE ECM on the dyno.<P>This will be compared to the custom EPROM I have using the KL03 ECM and it will show you how much power can be gained from the different tables without toying with the VRIS points. <P>The 8 WHP is under a very narrow RPM band width. Its mostly due to the VRIS settings. I dont think its worth a few hundred dollars. <P>The ZE has its timing advanced and there are differences in the fuel maps to match the Jspec VAF sensor.<P>There is no real magic behind all this. <P>Steve<P><BR>
