PROBLEMS AFTER ECU CHIP, whats wrong with my car??

hello guys! Sorry if my English is not the best.
I finally put the ECU CHIP in my car, which was bought from a user of this forum. But something is not right, has a bad idle, and small fails in the acceleration at first, then sometimes makes a "pull" and accelerates well. But the car would not be working and accelerating as it should.
When I started the car, it cost a lot, and being in idle the RPM goes down and up, and sometimes it goes down quite a bit. Then it seems to stabilize, but still has an abnormal idle.
When I accelerate the car, at first it accelerates well, then it fails a bit, it recovers, it hits a "pull", and finally it accelerates well

it is a b230ft, LH 2.2, ECU number 0 280 000 541, stock injectors 0280150357, IPD turbo camshaft, 10 psi of boost, accel super coil, IPD spark plug wires, new NGK sparkplug, new oem fuel pump, new oem fuel regulator, stock exhaust, new vacumm lines and hoses, new oem turbo, etc etc.
I followed the instructions to perfection, I do not know what could be wrong.

Could you please help me ?? Thank you

It needs to learn for a couple gas fill ups. Make sure to use the best octane you can get

Did you put a lh2.4 chip in lh2.2?

Lh 2.2 doesnt learn. It sounds like you have vac leaks.

I thought it learned a little from the O2 sensor, just not to the extent of lh2.4. TY for informing me

Stage 0 done first?

Thanks for the feedback.
I doubt there will be vac leaks, but I'll check everything out.

The chip I have is for LH2.2, not for LH2.4. But according to LH2.2, "it does not learn"

Find the following information in this forum:
"Q: Is there a run-in procedure for these chips?

A: Yes. For the chips to work, you need to let them run-in and adapt properly. I can understand that you want to go into boost ASAP after installing the chips and upping the boost. But please don't. Let the car adjust, re-adjust and "settle in" before you try to time your 0-60 or whatever.

I know it's hard, but please be patient.

It takes a while to get used to the changes.
It will run a little bit odd or even like crap at first.
The first 10 times under boost or so, the car will not show its full potential.

My recommendation is to:
* Install the chips.
* Start it and let it idle for a while.
* Drive around, let it warm up.
* Set the boost to its recommended setting of ~ 14psi.
(The boost can be set higher on the B204FT and B204GT engines, and even higher in some cases)
* Drive it harder and harder then "normal" drive for a while.
* Repeat a few times.
* A total of one hour or two of driving is often enough.
Now it will be showing ~ 90% of its potential.

It takes a day before it runs like it should.

After that you can raise your boost even more if you have the hardware to back it up. "

Do you think I should give you a little time?

Yes it is. I made sure to leave everything new before starting to give a little more power to the engine. The engine is rebuild, and has many new components. Before putting the chip in the ECU worked better than ever, like new.

From what I know it's used for fuel trim. Like a fine adjustment. But it doesn't "learn" so it's always adjusting and won't remember things the next time you turn on the car.

Ah, I've only ever worked on k-jet and lh2.4 240s

It should run just like before you modified your lh2.2 ECU motherboard to now have a chip socket to put in the new reprogrammed chip. The chip I sent you is same as stock just a bit more acceleration enrichment and higher rev limit. Everything else is the same so it should be exactly the same. I would say something went wrong in the adding of the resistors and capacitors and jumper wires and the switching chip and the socket and the chip. Did you notice the extra holes on the chip socket board spot? If you didn't put the socket in the correct holes on the motherboard and the chip in correct orientation it won't work right. Same with all the other added stuff. Also could be something wrong with one of the components you added. It's hard to figure out. Like I told you in a PM take a picture of the ECU motherboard where you added the chip and components so I can see how it all looks. Other then that I can modify a ECU I got here and put the chip in it and send it to you but might take me a while to get it done as it's that time of year for me to be doing other stuff that can't be pushed aside.

Dump a stock 541 back in there to see if it is the modded ecu.

The chip was placed perfectly, also placed by a friend of mine who is an electronic technician. I do not really know what can be wrong. Last Saturday I took the car to a motor booster specialist. We put a Wideband, check fuel pressure, injectors, and other things.
Actually the biggest problem was in the idle, and the mix was way too poor. As soon as you accelerated it was placed in 12.5, that is to say, the mixture was rich and it went very well.
the last thing we did was disconnect the MAF, and the idle was very good, but we plugged it in again and it worked badly.
Finally We removed the chip, the resistors and capacitors, and the car went back to perfect.
I really do not know why the chip did not work. I was really really excited and it was a real disappointment not to be able to drive the car well.
Can the MAF be replaced? What recommendations do you give me?

i don't know jack about your type of car, but have you looked at the waste gate?

yes, the waste gate is fine and working
