dude Posted May 6, 2005 Share Posted May 6, 2005 After slagging them off a while back i now have to admit that the AEM has completley taken me aback with the ease in which the mapper tuned it tonight , the freaky thing was alltering the transmission characteristics as we were driving and the fact that it drives (gearbox wise) completley different on the engine load , we have tuned it to change gear so much better on very light throttle than the stock eCU , mis throttle different again and it now changes at full throttle at 7500 rpm not before or after !!!, we have a tiny bit of fine tuning on the cold start tommorrow but the car starts and idles hot or cold with no throttle at all , idles at 1000 rpm with 1200 cc inj (we could lower it even more if i wanted ) revs cleaner than ever and drives in stop start traffic like a bog stock car , it feels less laggy than with the 67 i started with and is significantly quicker at 1.5 bar on optimax than it was at 2.2 bar and 118 , we have a rough idea of the HP from the duty cycle of the injectors and the car pulls right thru to 8000rpm so fast its unbelievable , Race fuel mapping tommorrow then Im now convinced that a lot of the probs in the past with AEM were old software and tuning related . You would not believe how quickly the guy has mapped it and it is the most economical at light throttle cruising speeds its ever been , if i was offered any ECU FOC tommorrow id leave it in thats for sure Dude Link to comment Share on other sites More sharing options...
JustGav Posted May 6, 2005 Share Posted May 6, 2005 Yup... I've stood by the AEM before, plus I like the fact that it is open unlike the HKS units... Now if only they could sort out the VVTi properly, I would have one in mine tomorrow... Gav Link to comment Share on other sites More sharing options...
Markie Posted May 6, 2005 Share Posted May 6, 2005 Problem with idling speed if engine has big injectors then? This normal? Link to comment Share on other sites More sharing options...

JustGav Posted May 6, 2005 Share Posted May 6, 2005 Hmmm, did not realize they had a drop in replacement, I know a few guys have rewired the VVTi harness to plug into the standard AEM supra Ecu.. I just like the flexibility it gives with the additional controls which can be wired into things such as aquamist and the like. Gav Link to comment Share on other sites More sharing options...

Gav Dude i cant belive what this guy was doing to my car it changed character more times than Mike Yarwood , at just 1.55 bar on optimax it is proper silly quick , feels quicker than 2.2 on race fuel last year and the afr doesnt even flicker at WOT Dude Link to comment Share on other sites More sharing options...

Guest Usmann A Posted May 7, 2005 Share Posted May 7, 2005 haha, it took me quite a while to understand some of the accel fueling stuff. but it does alot for the money ... bet it goes like stink now.... hows the bitch of a 74 spooling? any logs? id like to compare,roughly .. thanks.

U i dont seem to have any lag , ill get a copy of the logs and you can have a look , i will not be swapping on the small turbo for street use as i planned , no need TBh the car is now a bit dangerous for the road unless driven very sensibly Dude Link to comment Share on other sites More sharing options...

TLicense Posted May 7, 2005 Share Posted May 7, 2005 I take it it's been mapped using boost comp to be done so fast? As Us said it's a wicked bit of kit for the money. Now's the time to start as you'll love some of the features it has. Link to comment Share on other sites More sharing options...
Guest Terry S Posted May 7, 2005 Share Posted May 7, 2005 went in Dudes car today and it does seem to drive well:thumbs: Had a long chat with the mapper and it would appear that other make a few fundemental mistakes with the set up. We had a little play up against my car and it does go well, my brakes are better tho Link to comment Share on other sites More sharing options...

Now's the time to start as you'll love some of the features it has. 1.6 bar , pump fuel , perfect AFR's on WOT , starts with no throttle from hot or cold , idles like stock , drives in traffic , hauls ass , enough said IMO my mapper is God , ask Terry S if it drives ok in traffic , now mapped to over 2bar on race fuel (poor guy riding a ZX9R picked the wrong sup to race !!!! ) , BTW Terrys car is devastatingly fast and prob a better road car !!!!

TLicense Posted May 7, 2005 Share Posted May 7, 2005 it would appear that other make a few fundemental mistakes with the set up. Is this anything general or more specific to high hp cars like Dudes?

terawua Posted May 8, 2005 Share Posted May 8, 2005 what difference can it make to a BPU car? oh and also is AEM the best way to get 8000 rpm reb limit (along with all the other benefits?) Link to comment Share on other sites More sharing options...
TLicense Posted May 8, 2005 Share Posted May 8, 2005 To a BPU car it can do anything any other fuelling/timing computer do, plus a bunch of other things that only stand alone ecu's can do such as increase rev limits. However, it will take longer to set-up fresh out of the box than your usual piggy back type ecu's. However as more and more people get the AEM, there are more and more people with basemap's closer to your set-up that you can load as a starting point. If you mean will it give you HP gains, yes, but only in the same way as any piggy back computer will (ie you can lean out the overfuel and gain HP that way) The REAL added bonus is it's flexibility as a stand alone in that you can add more and more to it (which to be fair you can pretty much do to any end user programmable stand alone ecu) BUT, and this is the BIG BUT, as it's been mentioned on here many times, a programmable ecu is only ever as good as it's programmer. (Hence why good engine mappers get to fly around the world mapping peoples cars) If you want more information try here:- http://www.aempower.com with their dedicated forum here :- http://forum.aempower.com/bbs/index.php I think you'll need to register to use the forum.
