yep
set the base idle and adjusted the amm. Can't remember if I got the led working or I used a digital multimeter.

The issues are hard cold starts, poor idle on cold start, and light throttle response is poor, also very rich at WOT.
These these are not issues on the stock unit.
I have not yet de-chipped the unit to see if it is the culprit.
From my understanding the 2.2 cpu is the same worldwide I have 2 541s ?

Where did you get your chip from? Did you buy it from me or from someone else on the board?

It seems like only the Aussies have a problem with this.

Or do the Aussies have problems with setting the mixture right for some reason?

I have added/updated the LH2.2 ECU modification instructions.

Can someone please give me some feedback on that?

I am so use to electronics like circuit boards, soldering, programming etc. that it is possible that it might not be 100% understandable for the novices.

Great write-up but only one thing, think it's just a typing error. Are the numbering correct here?
Quote:
* Position B705 is a bridge between two solder islands. Remove that bridge.

* Position B702 should be open. Put a bridge between the two solder islands.

* Position B702 should be open. Put a bridge between the two solder islands.

* Position B1 should be open. Put a bridge between the two solder islands.

And the resistors and capacitors...

at the risk of sounding noobish, is there any way to get this stuff done on a 3.1 unit? i mean, no one has tried to crack it at all and it boggles my mind why it hasnt been.

First of all, it is NA. And second of all, they are very few compared to LH2.4 cars.

We could to NA chips for LH3.1 as well, but since we would sell so few it would not be worth it (unless you feel like paying close to 1000 USD for it).

no, no i wouldnt want to pay the extra money, hence the question. sad though, being such a refined system. well then, better get on with a 2.4 conversion :D

I get this question a lot. Read the sales thread please.

This time I will tell you what you will get and what it costs, but the next time anyone asks I will not be kind like this.

Taken from the sales thread:

Quote:
EZK + LH2.4 chip package, for NA B230F/FB/FD/FX. - NEW PRODUCT! -
Price: $285
Quote:
Price:

The shipping charges are included in the price.

Customers in the European Union (EU):
VAT (25% tax) is added to the price for residents in the EU.
To buy the chips excl. VAT you need to supply your valid VAT-number or get someone outside the EU to buy the goods for you.
Legal documentation/description here: Swedish tax agency SKV 552b, 8th edition
That means that the chip package will cost you 245 Euro. That includes shipping.

The performance gain for the B230 NA engines is not added to the first post in this thread, so I will cut you some slack there.

The B230F will gain around 10-15HP. The driveability will go up a fair bit and it will feel healthier. With other modifications you will gain some more power.

Read the entire FAQ thread and the sales thread for some more info. Also look at this thread: http://forums.turbobricks.com/showthread.php?t=143753

Okay I've read through all these pages and I'm not quite sure I have a definitive answer. I have not opened my EZK but I have a 87 745 TI so I don't think its chippable. I do, however, have access to a 94 940 t that is being parted out. Do you think I could pull the EZK from the 940t, chip it, and use it in my 740t with my ECU? Or where there changes from the 700's to 900's electronics I don't know about?

87 = LH2.2 and EZ117K
94 = LH2.4 and EZ116K

Exactly. They are not interchangeable.

You can however swap to LH2.4, but that involves a lot of re-wiring.

The LH2.2 is chippable too you know. The EZK of the LH2.2 system is not though, but most of it can be helped with some static ignition advance (like you might have read in the FAQ) where you just advance the distributor a little bit.

Hey I'm going to use your chips on my B234F+T engine and just going around 350hp for now on LH2.4.
The engine has 9:1 CR (ordered cp pistons for higher performance engine on e85, but i dont think i will run on e85 till i change the EFI) or what do you say? If I can run E85 fine on LH2.4 how big injectors and AMM? 350hp is fine for now

MAke a bigger AMM out of a 016 AMM (so that it gets up to ~3"), or make a slightly larger size out of a 012 (so that it gets to a little bit over 3"). It is a little bit of fiddling though, and you need to match the AMM and injectors properly.

Regarding injectors: At least 668cc/min. Preferrably 788cc/min.

668cc/min goes well together with a 3" 012 AMM. For 788cc/min you should make a custom AMM.

I have the stock 3" AMM from B204FT. so 788cc injectors and 012 amm enlarged to 76mm.
Does the stock fuel system pump enough for this? its a volvo 960

Well... 012 enlarged to 80-ish something mm. The 012 is close to 3" already.

And the single in-tank pump should in theory be able to supply the flow (I think), but it won't sustain it at a higher pressure. So it might not be able to handle high boost since the FPR will raise the pressure too much.

The dual pump system will definitely not be able to handle it.

Either way, replace the pump with a single Walbro, or even better, a Bosch 044.

I don't know if the 960 has one or two pumps. Check under the car. Under the front left door. You should find a fuel filter there. If there is a pump next to it, you have two.

The 940's from at least 1995 and up (may be earlier as well) have just one pump.

If you have two pumps, you replace both with just a single one. Remove both and install the new one in the tank.

The Walbro is virtually bolt in (a hose clamp or so is the only thing that is needed if you need anything extra at all).

I don't know about the Bosch 044, but it should be the same thing there. Just a hose clamp or two.
