Unichip Q - Check engine light popped up

[Tommisan]

Hi,

 

Does anyone have issue with check engine light after installing unichipQ version?

 

The workshop had tried to adjust the ignition timing mapping to a lower value (for low revs) but the engine light still persists.

 

What should the installer do to rectify the issue? Does it warrant for a second dyno to retune the ecu again? I am second guessing that the installer does not wish to go through that, but rather tried to play with the timing to get rid of the check engine light issue.

 

They have also tried to reset the factory ecu, but the check engine light still persisted.

 

My concern is I will not be able to know how much gain now after he started a second adjustment to the parameters. I mean in agreement, if such a situation occur, it would be fair to me to request for a second dyno. Do I have the right to request for a second dyno and retune? What I have paid for should be fuss free respectable gain from using unichip Q without compromising the engine relability.

 

I have also requested for on road tuning but the installer reaffirmed that dyno tune has a higher load rating than doing an on road tuning. On road tuning is not as critical.

 

I love the results from the first dyno, but sighs...

 

Any advices?

 

Cheers,

 

Tommy

[Tommisan]

I do not know what code, all I know is that the Check engine light popped up (when I was driving) after unichip Q was installed the day before.

frankly,unichip installer here is hopeless.not professional enuh.

[Tommisan]

Hi,

 

I would not comment on that as I am just a novice to the world of modding.

 

Not relating to this incident, there are definitely stall owners/ inventors who are selling snake products and are totally unprofessional.

 

Cheers,

hi dude,btw wat is ur gain in bhp aft e chip was planted n tuned.

[Try_conti]

any specific shops in amk to 'avoid' for unichip .....

[Versionv]

Ask yr installer to solve the CEL problem for you....it is under the trouble shooting part otherwise its cannot consider a proper installation liao.....

 

Alternatively get yrself a scan tool to clear the CEL whenever it lighted up....

[Try_conti]

CEL is there for a reason. Cannot anyhow ignore & clear one. Ignoring it now can lead to hefty repair bills later .....

[Hamburger]

pmed u.not so nice to write it out here.

[Tommisan]

About 12-15bhp, torque almost 20Nm gain

Hi,

 

They have tried to use a scan tool to clear the CEL, but was unsuccessful.

 

I am driving with more caution nowadays until I get the CEL cleared.

 

Cheers,
