On the base timing: I don't know much about the ED. But with the different belt setup, I would guess that the timing marks are lined up differently on the balancer (in relation to the keyway) compared to the EF.

Hello, I've got an EL Fairmont Ghia and I've done some mods to it:
- CMS stage 2a cam - CMS stage 3 head - AU Falcon head gasket - Pacemaker 4499s, high flow stainless magnaflow cat and 2.5" mandrel bent exhaust - Intake side is getting mods, bigger snorkel and territory pipe from airbox to throttle body - Running on Shell 98 I don't like is how unresponsive the auto is, you can floor it in D, and it takes about 2 seconds to think about it, before it kicks down a gear, than another gear and it takes off. I hear the J3 can control trans? Is there anything we can do to improve this other than a manual conversion? The throttle response is pretty laggy too. To me its like the auto box ruins this car, it feels slower than my diesel Focus even with all its mods (it probably isn't really, just feels like it). What can we do with the TI Performance J3 chip? Whats it worth for the chip and a tune? |

depends on what tuning you want. jase can do a custom tune and chip for around 200, but he'll need a dyno sheet showing AFR's. blank chips are $100. dyno tuning cost more. bpr advertise chip + dyno tune for $700

Just send Jason an email listing mods and any other requests like rev limit, shift mods, etc and he'll make up a tune to suit. I had huge cam, port job , hi stall and heaps more and he made up a chip which is nearly spot on. No dyno sheet required, you can have it dyno tuned later if you feel the need.

I have an EF XR6 running a 4TBD ECU (N4AG9 def). I have a question on the built-in cruise economy strategy (called MFASW).
When certain conditions are met, the MFA Fuel Multiplier Table is applied to the Fuel Stabilised Table (closed loop), leaning out the fuel by 5-10% in the low RPM and low Load areas. That works out to about 15.5-16.1 AFR. That's fine for fuel, but what about the spark? A leaner mixture burns slower, so running leaner normally requires more ignition advance to keep the peak pressure where it needs to be. So, there should be a separate spark table that kicks in at the same time as the MFA Fuel Multiplier. There is a Spark Table MBT MPG that would typically contain just a copy of the Spark Table MBT, so is effectively not used. Is this MPG table linked to the MFA Fuel Multiplier? Thanks for your help.

Yes it is. I have started using 5-10% more advance in this table after some good results on my own car (see the recently updated tuning guide section on fuel economy for info). Spark changes have a huge impact on economy.
PS: Thanks ranga83 & roughredXR6. Drop me an email Damoo and we should be able to get the details ready for when I return. Cheers, Jason

Cool! Thanks heaps. I must have missed that in the new tuning guide. Like my school report cards said: Must pay more attention
 What got me thinking about it was a test Roberto Arano did, published on http://www.efi101.com/forum/viewtopic.php?t=8139 The thread is worth reading. Like you, he found that timing has a huge impact on fuel economy: "timing seemed very critical 1 degree either way lost 3 lbs or so tractive force." That was on a base of 30 lbs tractive force (torque, basically) - so 1 degree either way made a difference of 10% torque at cruise conditions! Massive.

So jason are you continually trying things with your own car and when they work applying then to the chips you sell?

Yep, on both my EF and my brothers blown EB. The hard part is finding the time after the day job, plus I just got married and have been away the past few weeks!
Cheers, Jason

As some of you may have known, we recently got married, and have been away on our honeymoon. We're now back and are almost finished working through our back orders. If you have any questions about an order or were waiting for us to return please drop us a line!
 Cheers, Jason

Hi Jason
I have recently done more mods to my ED. It now has BBM and 5-speed manual, and have set it up temporarily with resistors for trans temp and inhibitor neutral. It now shunts under deceleration at lower revs, and the rev hang is giving me the s**ts. Both have gotten worse with the BBM conversion. Not sure if it's tune related but It has also developed a hunt (or surge) under light throttle at any speed which is now much more noticeable with the manual. Strangely enough it goes away if I disconnect the o2 sensor. Anyways, would like to get the j3 re tuned but afaik there is no one around my area that can do it. We do have a Repco service across the road from work with a Dyno Dinamics dyno, so if I was to get a few runs done and send you the results along with my chip for reprogramming what should I ask them for, ie. what info is best for you to tune from? BTW its still running the base tune you did for me, and she cracks. Idles perfect and pulls to limiter super smooth. Tried it without the chip today to see the difference. Idle flaired from 200-1400 and kept stalling, hesitation, big flat spot around 3000rpm, noticeable loss of bottom end power, it was a pig. Although the one time the idle did settle for about 10 seconds it sounded awesome. Really lumpy and high compression crackle. So glad I got it before I did the mods.

Howdy mate,
Glad to hear the chip has been working well! I think you may have introduced a vacuum leak with the BBM swap - if the idle is bad and rev hang has changed, it's possible you have too much airflow (either a leak or throttle stop too far open) or even the TPS isn't working. I'd check these things over before you do anything else. If you get some dyno runs, I can definitely update the tune to suit the mods and dyno sheet. Switching it to suit a manual will help a lot with rev hang. Cheers, Jason

It is hard to set base idle though as with the ISC unplugged it doesn't like to run below around 700, plugged in it sits on 550. I have set it by finding where it starts to upset idle, then backed the screw out 1/3 turn. Would base timing cause the hunting possibly? Had to set it by ear as timing light says its about 60º retarded. Was like that with stock ed drive and same after ef serpentine conversion so I got no idea what going on there..
