What clients say about ECU Guys in Santa Ana (CA)
-
My Hyundai dealership determined that my 2015 Hyundai Genesis 3.8 needed a new ECU. The dealership quoted me approximately $2500 to replace it. I contacted the ECU guys after reading their stellar reviews and they quoted me just under $1000. The customer service I received from this company from start to finish was exemplary. I would highly recommend them to friends and family.

Originally thought it was going to be the module, but when I pointed out a few things, he recommended to have the electric look at it. Very honest.

Sina explained everything to me very well and price was fair and all of my issues were fixed on my footwell module of my mini Cooper. I would definitely recommend them!

ECU Guys are the best... Very knowledgable and responsive. Took care of me and even made a special trip to get the final touches done for me. Would definitely recommend for any ECU needs.

Sina is 5 star professional. Brought in Ram with electrical issues caused by water damage. Sina ordered ECU, wrong part was delivered. Because of time constraints I had, I brought my own part which was installed and Sina charged minimal possible amount. As the issue persisted, next step was to change TIPM. Refurbished TIPM was installed as per Sina’s suggestion, truck is as good as new. For the same job other place was asking almost 4 times the money. Thanks again Sina

This is a review on for a ECU replacement & programming for a Ford Mustang 2006. Owner operator shop (owner is an expert in his field with a supply chain that can find hard to source replacement parts). My ECU was replaced and reprogrammed based on my specific VIN (i.e., no need to replace my CHIPPED KEYS). Affordable - I was quoted twice or three times local shop. Conversations were straightforward and professionals. Please note: The shop is strictly focused on computers. Your car may have issues that are mechanical in nature and not within your scope. Please also note - the root cause of WHY you computer failed will not be repaired replacing a computer.

I was sceptical at first but ECU guys went beyond and above. ECU Guys helped me find a replacement ECU for my Mercedes benz CLA 250 2017 and went ahead to programme at an affordable price. They Great are what they do. Thank you ECU guys you saved me thousands of Dollars

I brought my Lexus to ECUGuys, and Sina was incredibly knowledgeable about car programming and electronics. He took the time to explain the possible fixes and recommended the most affordable solutions without ever pressuring me into anything. Excellent service—5 stars all the way!

Took my car in to check the airbag and parts needed to be ordered. I brought it back, and it was replaced. On the drive home, my traction light came on. I called Sina, and he said his repair had nothing to do with that light. I decided to take it to a different place, and the issue was in the steering column where ECU just had replaced the airbag part. I called Sina and told him I was disappointed with his repairs.

Extremely knowledgeable. Took an ECU here for cloning after trying everything mechanically on a 18 WRX with a stuck P0018 code. Car started up, no codes, no issues, passed smog. Would highly recommend going here.

Air Bag Module! My 05 Chevy Silverado had a the airbag light on, along with the security light and battery light and the gauges that would drop here and there. I diagnosed it myself but, Sina gave me a great deal on removal, refurbished Module and installing. This is the second vehicle he helps me with. Great service 👏🏼

Extremely unprofessional , very bad. Promised to code- reprogram my 2019 BMW power steering rack and pinion. Never did it. Guy named SINA charged me $250 for noting. I still have previously fault message on dash board. He doesn't have equipment , doesn't have knowledge . Just big crook.

Car been in ECU Shop for over month could not get fix after demandiing more money.... He have the nerve to tell me he best in business. Paid for unfinished job. Worst experience ever. Had it fixed elsewhere within 3 days. My experience was horrific, bad business practice to lure new clients. You better off elsewhere.

Beware: Run! super shady!! see ECU Guys yelp reviews!! I wish I had read the yelp first. the google reviews aren't bad. I requested assistance with my friend's 2007 Audi convertible computer control module and repairs. my son pulled the ECU because of errors/codes on the computer. I then found Cina on Google. He reprogrammed the computer for 431.00. It did not work when my son installed it. We towed it to Euro Coast (Sevon) on Jan 27th, 2021 in Costa Mesa. He got the old computer to work but it would not remain running. (the original problem) He said that the new one wasn't working at all.. Cina said that he could fix the car and that Sevon was wrong. We were hopeful so We towed it there on Jan 31st, 2021. He could not fix it because all the control modules did not match the vin#. He said that he felt bad that we paid for repairs and the computer and that he has a friend that could sell the parts and 100,000 mile engine and give us up to 1200.00. smooth and charming talker! He told us that he would put it in the back lot. He asked if I had a zell account on my phone to send the money to. we gave him the signed pink slip. On Feb 24th - I texted him about the money. he texted that he sent it to the recycler for 120.00 and then told my son that he sold it to a tow driver for 120.00. Cina texted me that he had put 120.00 in parts (the clock spring module and a couple of sensors) and that it didn't work so he had to recover his money. He denied that we ever had a conversation about parting the car out so that he could zell money to us. basically and outlandishly called my friend and I liars. My bad. I didn't know that such unethical people still existed. terrible way to run your business... in a world of social media. He is refusing to give any money back. He is on the same lot as John's AAA towing and recovery. He is an outright liar! His word is not his bond. Cina should be ashamed of his treatment of us. He works with Allan who told me that he and Cina do not provide receipts. that that is how they do business. I felt that since I had the texts and John's towing is a AAA sponsored business (trucks are on both sides of the fence on same lot and John uses the same address. ) that our business deal would be ok. but no: We have been had. We Will take him and John's Towing to small claims court. Super shady business. UPDATE: ECU guys are not affiliated with John's towing. rather they rent from him. John's towing is old school ethical and professional and is very kind family run business. Cina on the other hand is from a shady side of life and appears to be pleased if he can get one over on you! Beware. He did come through with 450.00 after much back and force with my son and my offer to sue for 10,000.00 - primarily in punitive damages.

Sina is an awesome guy. Really made me feel like family. I took my ECU and he programmed same day. Dealership was giving me an appointment a week out. Sina's price was also a fair one. Thank you for your help. Will definitely recommend to friends and family.

DISHONEST CROOK // STAY AWAY Just a read a recent review with a similar experience. I gave the guy my car with the security light and locked key/no start symptoms. I told him all of the issues I was having and that the ECU that was in the car probably wasn't programmed properly when replaced. He said he can fix it, he looked confident he could do so. He notifies me my car is fixed and ready. I travel an hour to get to his shop and he tells me "the check engine light is still on". I'm wildly confused because the check engine light wasn't on when I gave it to him. He proceeds to tell me that it was. I actually have a code reader myself and when trying to diagnose the initial problem checked for CEL codes. At this point he's still asking for payment. The car did start, but this was an intermittent problem, as told. He proceeds to tell me the reason my car is messed up is because of the engine light, not the ECM, and I shouldn't have changed that, EVEN THO MY ISSUE WAS THE ECM! I never had a Check Engine Light on in the first place. He also proceeds to tell me that the last ECM was fine but it just wasn't programmed (He had the ability to just program that one for less) Only to 5min later say he didn't check the old ECM at all. He was spinning all over the place to absolve any responsibility SINA, then offers a wager... IF he puts the old ECM back in and the check engine light is still on, I owe him an additional $150. If it doesn't come back on, then I guess "oh well, all is good now!" So to make his customers rest assured he says "you better be right or you're fee is out the wazoo" He typed a generic invoice up that also doesn't explicitly mention a check engine light, like any other shop would for liability reasons..and didn't even have my correct license plate on it. We both inspected the car at the time of delivery, and I verbally mentioned just the security light being on. HERE'S THE KICKER!! MY CAR RAN FOR 24HOURS AND THEN BACK TO IT'S ORIGINAL STATE Not to mention his POS machine doesn't work so I was forced to give him cash, so now no real financial record. HE BASICALLY ROBBED ME FOR $360

This place is awesome. Shout out to Sina, he is the guy you want to talk to about your ECU problem. I have a Volvo v50 and I had a P0600 code. I Spoke to Sina about tht, and it was not a problem for him. He is very knowledgeable in his profession, down to earth and an honest guy. He'll walk you through the problem and explain exactly what he will do to get the job done. Highly recommend. This is a one of a kind shop.

Great customer service! Tech was very helpful and thorough. I would recommend ECU Guys to anyone having electronic problems with their vehicle! ECU Guys fixed a problem created by another shop. Thanks ECU Guys!

Ford charged a huge "diagnostic" fee to give us a repair quote just a few dollars under two grand. When I reached out to ECU(due to a YouTube video), they quoted $850 but came in just a little over $500. There was a small addition adjustment they did and only charged for the part, not the labor. They were courteous, professional and left me wanting them to do additional repairs. I'm arranging a front-end/driving light repair and I'm looking forward to them doing it for a better price, done well and in short order. I can't thank them or recommend them enough.

my experience with ECU guys are based upon few times satisfaction diagnosis on my lap top computers. his excellent service with fair charges are recommended. mike H. Javon December 16, 2020

Sina is a great guy and is very honest and knowledgeable. Got the job done for less than half of dealer quote. Would use him for any electrical problems you have on a car as if he doesn't know how to fix it, no one does.

I have used ECU GUYS for computer reprogramming twice sofar. I have been very happy with their work, they know what they are doing. They are the dealers alternative, they are dependable, quick and prices are reasonable. I will definitely use them in the future and I highly recommend them to others too.

Sina was very professional and prompt on his replies, actually everyone in the shop was friendly and very professional. Sina understood my situation in needing a new ECM reprogrammed and he even went the extra mile to find pricing on a new and used ECMs. I ended up purchasing one from a salvage yard and Sina did an amazing job getting it reprogrammed. I just wish I knew of the ECU Guys as I originally purchased a pre-programmed ECM online which turned out to be a nightmare (Sina knew of the company in which I purchased the ECM from without even mentioning the company). Price in my opinion was good and If I ever need to have another ECM programmed in the future, I will definitely go back to the ECU Guys. Thank you Sina.

Sina is very professional and was able to update the ECU on my 2002 Chevy Silverado 1500. My truck was 2 updates behind and after the update the truck was able to hold each shift longer and made the vehicle more responsive. I don't have poor acceleration problems anymore and no more CEL issues under heavy acceleration. I also changed the fuel pump and the fuel injector. If you have added or changed parts on your engine, I recommend updating your ECU for better performance. Thank you, Sina!
