View Full Version : AFR Tuning pre-christmas special - Link Engine Management
The doors open to AFR Tuning Ltd on 2nd Jan, but I've been getting a lot of enquiries for the Link ECUs so paid for trader status early in order to run this group buy.
I need to order 10 units to achieve these prices, but I can mix and match the various options. These prices are an introductory price and will be slightly higher normally.
All prices include unterminated loom, map sensor, vat and import duty. Prices are :
Link G3 with 2.5bar MAP sensor £470
Link G3 with 5.0bar MAP sensor £500
Link Plus with 2.5bar MAP sensor £785
Link Plus with 5.0bar MAP sensor £800
This does not include delivery in the UK.
If you want a plug and play loom, then Ryan will happily sell you one for £130 :)
If you have a TT then you need a Link Plus because of the number of inputs required.
If you have a manual single, then you can get away with a G3 but you will have limitations.
For a comparison of the two units look here http://www.linkecu.com/products/engine-management/feature-comp
For the autos, Ryan and I will do our best but the Links have NO auto transmission control. For full auto control, I would have to recommend the MoTeC or an AEM.
Don't forget that the MAP sensors are absolute psi, so with a 2.5bar sensor, you can 'only' run upto 1.5bar of positive boost.
Finally, I am currently working out package prices for fitting and mapping and I will update the thread once I have worked these out :)
So, get your names down ;) ECUs will be secured with a 20% deposit and the balance when they arrive.

2. magictorch - LinkPlus 5bar
3. Lebsteif - Link G3 with 2.5bar MAP sensor + Boost solenoid

Holy crap that is cheap matt. Saves me getting customers to import them now. :)
Just to add the Link G3 LEM which is the cheaper one is no good really for a TT or a Single due to problems with acceleration enrichement due to having to run grouped injection as the link g3 LEM only has 2 injector outputs.
Get a Plus though and you have 8 Inj and 8 IGN outputs plus another 8+ spare outputs for boost solenoids, water injections, VVTI, shiftlights, ICV Stepper control and much more.
With the N/A and N/A-T i have not encounted this problem so the Cheaper G3 LEM can be used.

Yea i was telling Matt a few minutes ago about how crazy those prices are!!
Great deal!!!
Also FYI: I think you can download the interface on the support site and familiarize yourself with the unit before buying it. My understand is fairly easy to tune with.
ryan!
i want link plus now:)
nice prices,
good luck matt

.
The User Interface is very similar to the New generation Motecs and has been designed well so owners can make small tweaks and adjustments if they need too with help of mapper.
But the ECU's do not come with any base maps like powerfc's etc so everything will need to be configured to get it up and running, so i highly recommend you get it tuned by someone who is familar with the ecu. :)

Ideally i would of done my manual conversion before fitting my single but i havent so....if i fit a Link on my auto and then convert to a manual what would i need?
Jamie
What are the timescales like on this?
As soon as we've got 10 mate, you need one urgently ?
Matt some VERY good prices there! I dont need one at the stage my car is but would definately have signed up if I needed one well done!
Just the opposite; I'm not in urgent need at all, but always like to take advantage of a bargain... ;)
I'll need to have another chat with Ryan first too :)

I can confirm how good these ecu's (and the mapper) are...
I've learnt such a hell of allot of the interface and how it works.. I can even partial map it myself now... Well at least the top half of it on the fueling side..
Excellent peace of kit..

Cool, no probs :)
And if anyone is wanting customer feedback on how brilliant these ecu's are.. Feel free to PM me.. I will give my honest and frank views.. (in case of this piece of case) brilliant :)
They are some good prices there Matt. I will be getting a Link Plus 5.0bar from you. Just need to sort some other bits out first, so will not put my name down yet.
But please keep me posted :)
Ryan: Will also need a Plug and Play loom, will let you know ;)

Both G3's can be used on an auto by either piggy backed or with a Supra Stick Auto Controller ECU and use an G3 output to modulate the line pressure control solenoid (if you are clever you can use a change over relay and a third output to switch between two line pressures modulation frequencies like the stock ECU does in manual mode).
The Supra stick, as well as two auto shift maps, also gives you a REAL paddle shift manual mode and trick lock up controls like paddle after touch to control wheel spin on big power motors and lockup in all gears (and it's sub £300 landed so STILL cheaper than a MoTec or AEM).
http://www.latentsolutions.com/index.html
I know they don't list the MK4 Auto but that's because of the the line pressure solenoid which it doesn't control. The G3 should be able to do that bit on it's behalf.
Ignition retard on shift is all off, but then it doesn't appear to make the shifts on the MK3 box any harsher than normal.
I reckon you could do a stock TT on a LEM spec if you were clever. Just set the Idle on the stop screw hot and use a A/C idle bypass off a MR2 or similar for your cold idle up and you free enough outputs to drive the seqential turbo VSV's. I've done this one a couple of MK3 Supras and it seems to work fine.
Oh! AVOID second hand Link G1's as on option on a MK4 Supra TT. The internal subboard had big issues decoding high freqencies that appeared as a misfire between 5800 and 6600. This was only with engines running 4+ignition outputs on Subboards called "SUB24NEW". The MR2 subboard had the same problem as we found when going with Caldina COP coil packs.
I doubt you will ever find a G1 configured for a Mk4 Supra but if one pops up on ebay run away.
I hope this info proves useful to someone planning a Link G3 install.

Hi Lyndon
Thanks for some of the info above mate espically about the SupraStick never seen that before. :cool:
Having looked into this question a fair bit recently i agree with you that the linkg3 plus ecu can be piggybacked onto the stock auto ecu, letting the auto ecu just control the box.
But the Shift Retard function is vital. Many people in the states were not very happy with AEM in 2002 as they released their ecu stating its fine for a Auto mkiv but did not add the shift retard setup in the system. Without this the Box's were being killed off in no time. Now i am not willing to let any customers car go away from me knowing that in a couple of month's time they will be having to look for a new tranmission.
The factory ecu goes to great lengths to reduce the power/torque on the shifts by pulling the igniton timing and if this is not setup on a Standalone then it will only be a matter of time before it breaks the sprague.
Link are aware of this and ive been told that they will look at adding this feature. I did think of using the flat shift function but have not tested yet to see if it pulls the power enough and shifts nicely.
Also the Link G3 LEM on some TT supra's is not great at controlling the acceleration enrichment. Link know about this and have experienced it as well on other 6cyl+ cars running batched injection. Hopefully they will be releasing a update soon as Ashley@link has told me its not finished but in testing. With this resolved the link g3 lem would be a great upgrade for even BPU owners with its price tag.
Ryan
Good info guys :thumbs: And will definitely be doing some homework on the SupraStick !
See if you can source a nice paddle set to go with it too Matt :)

Very interested in a Link if you get it to run on my auto!!!
Thank you for PM's Matt and Ryan;)

so can use auto boys run link now Matt with this new find? Or should i still track down a Aem ?
Sorry mate, from looking at it briefly it seems that the Suprastick is a programmable control over the shifting points. The AEM has a shiftpoints map built in because it has full auto control. The important part for the auto is the ignition retard just prior to the gear shift, and the Suprastick doesn't appear to give you that.

1. JustGav - LinkPlus 5bar
2. magictorch - LinkPlus 5bar
Can you get the boostcontroller module as well and what price?
Do you mean just the boost solenoid and wire this into the Link to allow the Link to control boost ?
1. JustGav - LinkPlus 5bar
2. magictorch - LinkPlus 5bar
3. Lebsteif - Link G3 with 2.5bar MAP sensor + Boost solenoid
trying to justify, getting one to replace the aem:rolleyes:
Who would map the AEM though Gaz?
:innocent:

Matt, got a couple of mates interested in these, is the gb still going ahead, if not could you pm me prices on buying these outside of the group buy, cheers bud
Hello mate. Well still going ahead if we can get 10. I'll push this and see if we can get it up and running. Problem is I had a lot of interest but when I explained about the way the Link cannot fully control an auto, some dropped out - which is understandable :)
OK bud, will keep my mate informed :)

As Yoda said, "There is another" auto controller that can do everything a Supra needs ;)
Unlike the Suprastick I haven't had a chance to play with one so I can't comment on it's real world ability. But it has all the same sort of feature set, Paddle shift , dual shift maps, but with PWM line and accumulator pressure control maps, fluid temp safety correction maps, user selectable digital outputs (Pre shift retard warn for the G3 maybe) and shit load of other clever stuff.
It costs about £150 more that a Supra stick but does have nice a Windows GUI. Shame their other products look a bit toilet.
I would post a link up but their web site seems down at the moment. When it comes back up I'll edit this post.
Edit: Seems to work now : http://www.powertraincontrolsolutions.com/content-4.html
Should give RyanG some bed time reading :D

Thanks Lyndon, be very interested to see it :)

Updated.

Okay, I have to place an order with Link tonight. Doesn't look like we will make the 10 units this time but we could make 5 or so and this would mean the following prices.
Link G3 with 2.5bar MAP sensor £530
Link G3 with 5.0bar MAP sensor £565
Link Plus with 2.5bar MAP sensor £850
Link Plus with 5.0bar MAP sensor £870
If you are still interested, please PM me asap. Shame we couldn't make 10 as the prices really are good, but I'm sure I'll run another EMS GB later in the year.
I will PM all those interested too.
Thanks
Matt
Edit: I have to add that the Links do not control the auto gearbox and are therefore unsuitable for an auto at the moment.
