I rigged up my LM-1 on a mates cossie the other night only to find it running very rich (8.5:1 afr mostly on boost).

He recently had it setup with an off the shelf chip from a fairly well known tuning company and hasn't changed anything since.

I understand that an off the shelf chip will be set on the safe side so as to cater for the slight variations in specification on different cars but would you expect them to set it soooo rich?

I haven't had much experience of off the shelf chips for cossies so i thought i had better ask?

Stu or Karl, if you knew the spec of a car, how close would you expect to get to optimum fuelling from a chip with out live mapping?

 

wouldn't that be down to whoever set the car up ??? ie the fuelling

 

Chip and setup was from the same company.

 

ahh ok ..

 

i had an off the shelf chip from Stu, and apart from the known problem i had past 5500rpm, the AFR was 11.5 on boost til then

Even with an off the shelf chip,the setup should have sorted the fuelling much better than that

 

8.5:1 is madness. I am surprised it burns it ok to be honest and would expect missfires galore.

 

The car was run on a rr and their wideband showed it running very rich. We double checked with my wideband in the evening and it showed the same results.

So two independant tests showed the same results.

When i went out in it the car didn't feel as urgent as i would have expected.

When the owner contacted the tuner he gave a speel about settining up on the rich side as expected, and that the only way he could really change it is with a live map at a cost of another Ł????.

Would you:

A: Go back and ask him to sort his chip out free of charge

B: Go for the live map and ask him to knock the cost of the chip and the setup of the price of it.

C: Just shell out for the live map.

D: Ask for you money back for the chip and setup and take your business elsewhere?


We could probably get an improvement on the fueling all the way across the range by knocing back the fuel pressure but the car owner is running stock pressure and a set of greys and i am reluctant to do this as i am un sure of the effects on atomisation/spray pattern??

 

E buy a chip from stu

 

They obviously don't know what they are doing, so take it back IMO....

 

Greys, say no more. 95% of off the shelf greys chips i see are like this, not to mention the 7.2:1 old Cosworth spark map that drives like crap at bottom end

 

Thats the problem, they are actually quite a well respected tuner with motorsport pedigree.

Thats why at first i thought the RRs wideband sensor may be telling porkies and double checked it with mine!

I was sure they wouldn't have let it go out the door running like that, but apparently they did??? The setup/chip was only done 3 days before the RR day.

 

or F for fuck all that and pay stu for a live map

 

It doesn't idle right either missing all over the shop.

 

Are you confident the rest of the system is ok though?

Cam timing, air and water sensors, etc etc...

 

It is not my car so i cannot guarentee these things, however surely the tuner should have noted any probs when working on the car and made the owner aware.

The owner has since contacted the tuner to find out why its is running mostly 8.5:afr on boost. The tuner did not dispute that it was running that rich but said that it was set up like that to be mega safe!!!

 

Oh well, not a lot more you can say to that really. If thats teh service they intended to offer and they are happy with it, then thats teh service he has bought. Job done.

 

I know. It seems strange. I expected more of this company

Stu, could you pm me a price of one of your chips if you have anything to suit greys, t34, 7.8cr, rs500 IC. Will get you are more detailed spec if needed.

 

Done.

 

8.5:1 is safe now is it?


borewashtastic, not safe at all.


Name and shame the company IMHO

 

...well my karl off the shelp map wernt too shabby with a little tinkering i am running around 11.5 to 11.9 on boost...and around 13.5 cruising

8.5-1 is mad...bet the fuel consumption aint too special ...be interesting to put my lm1 on the EA off the shelf mapped escos thats on greys.

 

Dissapointing service, but not really my place to name them on a public forum.

 

but youre dying to...............if thats what they offer then maybe people should be forewarned.

are they based in congleton by any chance..?

 

got my chip from stu ..set up by MAD .. drives lovely

 

Where? i dont think so.

 

it snot who i think it is then...

 

8.5?!

MY car coughs at 9:1!

 

Is this Matts Car ?

Steve.

 

It certainly sounds like it

 

But is it ??????

Steve.

 

i didnt think the LM-1 would measure a/f that rich

 

 

Gareth, you are right. It just about managed to measure 8.5:1 and then went into sensor error mode "too rich".


And yes it is Matts car.
