few problems just had my car itb'd

[Nick r26r]

Hey all , just picked up my car from a place called m tech automotive , they have fitted jenvey throttle bodies and there v4 ecu , the car has 428 cat cams , 182 manifold , de cat and janspeed exhaust , and few other bits and bobs , and it only made 182bhp, the problem is the car has no low down power any more :dapprove: , it seems like it only starts revving when it gets past 3.5k revs and is very lumpy when pulling of , the thrust bearing is also rattling its tits of , had a brand new clutch 200 miles prior to going there (sachs) , does this happen when they put it on the rollers to much and havent got a big enough fan to cool the engine , the guy there matt assured me the car would be running fine after the throttle bodies but it isnt , im going to ring them up tommorow and get it back into them just want to know if anyone has any ideas what ups with it , they also had the car nealry 2 months doing it so had it ages

what work have they done exactly.

itb's, ecu and map?

 

[172Ben]

Is this the place that stupidly cheap? 182bhp is very low for the mods, but it's only as good as the mapper really.

Sounds like a dud map maybe?

 

[Gray]

Sounds like the mapping is utter crap... most 1*2's make that power with breathing mods!

Do you have any RR print outs?

 

[Nick r26r]

yes , itb's ecu and map , they have taken the old ecu out though ?? the car also looks like the battery is not charging , i done some research and the guy is good at mapping cars (obviously not clio's though) , i know most clios make that with matched inlets and a remap so it is crap

 

[Gray]

These guys sound good! Why have they removed the standard ecu?

 

[Nick r26r]

the car also runs like a bag of sh11t down low , splutters and doesnt want to rev properly till it hits about 3.5k ,

 

[Nick r26r]

These guys sound good! Why have they removed the standard ecu?

god knows ,

 

[Russ_16v]

Id say crap map mate

 

[Greeny.]

Just take it back?!

 

[172Ben]

I always thought u left the ECU in place, I know mine is.

 

[drhowser]

Hmmm. I was going to suggest the classic timing, but shouldn't be that.

Did they give a reason for taking the old ecu?

 

[Nick r26r]

they said there ecu wasnt compatable with it , i will be taking it back just checking to see if anyone has a clue to why it is running s**t ??

 

[Nick r26r]

I always thought u left the ECU in place, I know mine is.

theres is a stand alone unit , not piggy back , may have to go omex though if it works out to be ecu

 

[drhowser]

Ditto.

 

[drhowser]

I think the renault ecu controls quite a bit more than just the engine though.

 

[Gray]

I wouldn't of accepted the car back..

how much did you pay for the work?

Any photos of your engine bay since the work was carried out?

 

[marinemackay2003]

2 months??? wtf iirc K-tec do a drive in -drive out on same day

sounds to me like they have fkd up some how and no offence but just tried to mug you off with a cover up

get it back to them pronto

 

[172Ben]

Yeh, mine is on standalone, but still has the standard ECU

 

[drhowser]

definately this!

I think you may be about to have a few problems!

I would put in writing everything I wasn't happy with and decide on a time scale for them to rectify matters.

They have had your car a long time already!

 

[Nick r26r]

£2100 , will be getting it back there in the next few days , will get photos up tommorw , the work they have done is quite messy mind , picked the car up at 8 o clock and didnt really get a good chance to give it the once over

 

[172Ben]

Maybe to cheap.

 

[Nick r26r]

they tried saying more but as they agreed a price before the car went there i wasnt paying it as i made sure a price was agreed , its not very good from a companie that specialise in throttle bodie conversions , regardless of the car , they even had a how to install throttle bodies to a clio print out on there desk ???

 

[Gray]

To be honest... If I had spent just over 2k on my car I would expect the work to be spot on! And not accept it back until all is correct.

If on decent engine management / map your set-up should be making just over 200bhp!

 

[Nick r26r]

my mate had a similar set up and his was making 210bhpon omex 600 with jenveys and 428's

 

[172Ben]

Take it back, explain what's wrong. Agree with them a date of when you want it sorted by, check where your O/E ECU has gone.

If it doesn't work out, I'd be asking for it to be put back to standard and go elsewhere.

Wouldn't trust them to get it right.

210 with cams? I make 204 standard engine and cams

If you need a second opinion on it, these guys are in Kemble.

Very good indeed!

adeyspec racing , 214bhp it made i think , 204bhp is good , regretting ever going to this companie now as they seem like they havent got a clue what they are doing , but assure me they have

 

[PaulyA610]

I drove the car home and it is deffo not right. There is no low down grunt and the power does not come till it comes on cam. It also stinks of fuel inside the car and from the exhaust you can smell un burnt fuel!! The wiring needs tidying up too. So I agree send it back, but I am still not convinced they know what they are doing with renaults!!! I hope it gets sorted as nick was very dissapointed which suck's after paying a fair sum of money!!!

 

[Russ_16v]

Talk to them mate, im sure if they are a good company then they will sort the problem out.

The V4 is a good ECU, i think there is a mapping problem with you saying there is no low down power

 

[Nick r26r]

they assured me it wasnt mapping though and when i said that is very low he told me it was not all about figures and about how it drove on the road (obviously not) and told me he maps 100's of cars from race cars to road cars , they can have the car back till it is sorted and making good power , cheers for all the replies guys

 

[172Ben]

He's right in terms of it's not all about the numbers, but most make around 198-20?bhp.

So it's defo abit down.

 

[sideways danny]

it's megasquirt :dead:

Definitely badly mapped. Probably guessed the low end map and just done the power mapping, which is totally arse about face

it doesnt even feel like 180bhp , my mates 172 cup was all over me down the bypass

 

[Nick r26r]

are megasquirts really that sh1t??

 

[sideways danny]

of course it bloody is!!!! it's a hobby build ECU. Professionals dont use megasquirt

 

[Nick r26r]

do you reckon it could be ecu related then , the ecu not liking the car ?? what about the vvt does that run of the ecu?? 1000+vat they charge for there ecu fitted , seems a bit of a rip of

Seriously, agree a time limit with them, and get it in writing!

It may sound ott now, but it could save you a LOT of pissing about later.
