Hey guys, How r yas?
TOP job with the forums, couldn't believe when Autronics took the website down and replaced it with nothingl. They've certainly lost sales with not much support out there. I've had the SMC in the Lancer for the past 8 years or so, but have sinced moved onto other computers, where theres more support. Problem is, the SMC has been BULLETPROOF for me, and has saved the motor from much abuse. Before the SMC, I went through 3 motors, and have only just had to rebuild it recently.

The problem I ALWAYS have, is that I'm located 400kms away from Perth. And even then , if I wanna take it to Perth, the decent tuners are understandably busy and only got time for their core rally/race/drift cars. Booking in 2 months down the track is not good for me, cause I don't know what's going on tomorrow, and I only get interested in the Lancer when my other cars fuck up.

ANYWAY, enough of the other stuff...


The Lancer has been worn in and had MANY oil changes. It has a set of RPW's killer cams, ceramic coated pistons, etc, etc. Compression ratio is at 7.8. I have just put on a TD05 on it but it still has the base running in tune from where RPW in Perth got it done. Once upon a time in the lancers hayday, it was making over 300 at the wheels with a Turbonetics Turbo on it. The problem was, in my town we have lots of roundabouts and I like the boost to be more usable down low. The turbonetics was coming in at over 4000, whereas the TD04 was spooling up fast under 3000. Hopefully the TD05 with the right tune can crank in early...

Me and my mate have bought a 4wd dyno, so getting it logged isn't a problem, but don't laugh at the mapping, cause I can't remember what i've changed from a few months ago :)

Here's a map, and a log in the zip file, any suggestions (or a better CAL file :) ) on anything major before I TRY tuning the base fuel and ignition maps?

Any help would be extremely grateful !

Well, I'm not a moderator here but perhaps the swearing could be left at performanceforums.com to start with.

From looking at your log file you need to fix whatever the problem is that is causing the Sync/Cyl % to vary from 75 to 108 before you start to do any tuning. As the Cylinder position is derived from the same drive as the Sync signal it appears that you may have timing scatter to deal with also. And if you don't fix that you will probably be doing another rebuild soon.

As to the cal I think you should post up what you had before you started changing things in it. That calibration needs a lot of work. The Base fuel multiplier is obviously incorrect (what injectors are fitted? part # and flow rate), the Acceleration tables are doing nothing, the Open Loop Fuel table isn't enabled and all the Warm-up related tables look like they need attention.

Mode 4 has a value of 40, probably do not do any harm but best to set to 0 since it has no assigned function. You have also + Ve Ignition O/P so you use a MSD or other positive triggered ignition. Also set Mode 7 for Anti-lag by switch and 75 degrees cylinder pulse.
Would prefer to have open loop enabled to take advantage of the Autronic superior fuel strategy. If not enabled the AF table is not in use.
Also the Basic acc settings and more seems "different", I have done some changes in the file you can use when going for fine tune at the dyno. You have base ignition table at idle and it ramps between 500 to 1000 rpm so I would go for idle table or changing in the base ignition table.
Attached is the corrected file except for idle ignition.

Ian was quicker than me and he is right the file need some jobs.......

Firstly, I apologise for the uneccessary vocabulary, I've edited them out.

I understand it's a mess, and I'll get to work right away sorting it out hopefully. I'm new to tuning, but have read everything I can find, so with any luck (or lots of it), I can get it straightened...

Thanks for the help !
I understand time can be valuable, and if you're short of it, maybe we can sort something out to cover it. It would be a hell of alot easier if there was a course available of some sort even if it was in the eastern states. Cause the problem with flying someone here to tune it, is they probably wouldn't want to pass on their knowledge while tuning on our dyno...

Cheers again !!!

You need to talk to Buzzard. His field extended to Kalgoolie and Perth just last week.

The first thing we need to start fixing your cal is the injector information. Are they still standard (390cc white colour I think) or something else. List all the numbers you can find on them. Any more information about the RPW killer cams would also help. Did this engine start life with a distributor or coil packs (did it have one tooth on the Sync sensor or has it been modifed to one).

Have you had a timing light on the engine to see how much timing scatter there is. When you rebuilt the engine did you replace the cam belt tensioner with a new one or did the old one get compressed back in with a vice?

Did you recently purchase a Mainline dyno ?

It makes no sense for most tuners to teach you, as you will then start cutting into their market. My main market is in Newcastle (Australia). I would be pleased to show you what I can in the time available.

This is a forum for professional and amateur tuners. Please remove all profanity from your post.

Send me a private message if you are interested.

I checked out the cal file that was stored when I got the car back and it's the one I uploaded. I mustve restored it into the ECU after the changes I had made a few months ago while just playing around/learning.

The first thing we need to start fixing your cal is the injector information.

I found the injector number, 0280150363, and after searching the net, flow rate is found to be 638 cc/min@3bar and the resistance is 0.7 ohm.
That was found here: http://www.injectorcleaning.co.uk/flow.htm
They r still the injectors from when I originally had the big turbo, unsure why the tuner didn't change them...

Any more information about the RPW killer cams would also help.

Adv Intake 266. Adv Exhaust 256.Valve Lift Intake and Exhaust both 0.375.

To the other questions, I've just finished work, but later on when I wake up I'll check the timing, and also find out whether it wouldve started with a dizzy or not. I'm pretty sure it did...
The cam belt tensioner was replaced with a new one, aswell as putting in vernier cam gears.

I hate to say this... but the ECU came up with error CMOS RAM Memory Loss. So that means it needs a checkup, even if it still seems to work??

You need to check and see if the injector resistor block is still fitted and wired into the system
